Introduction

Congratulations for choosing the Modular Advanced Remote Starter and Security System. The MARS offers the security of an antitheft alarm, the convenience of keyless entry,
and the luxury of starting your vehicle's engine from the comfort of your home or office.
The MARS-33 includes a 2-way controller to operate the system, and receive pages from
it, and the MARS-32 includes 1-way transmitters, which can operate both models. The
MARS-32 may be upgraded to 2-way operation by adding an optional kit, the MARS-03.
Otherwise the two systems are identical, and instructions for operation are the same.
It is highly recommended that this system be professionally installed, as the sophistication of the modern automobile and the complexity of this type of product installation is
often beyond the abilities of most do-it-yourselfers.
Safety Considerations
✓ This unit is for vehicles with an automatic transmission only. Installation in a vehicle
equipped with a manual transmission can result in property damage or personal injury.
✓ This unit is for fuel injected gasoline or diesel engines.
✓ Children should not be left unattended in, or be allowed to play with the activating Trans-
mitter or Controller of any remote starter equipped vehicle.
✓ Do not use the remote starter feature in an enclosed garage or other structure.
The MARS is a very flexible system. It has capabilities and features which may or may not
be utilized in your installation. It also has many programmable features which can affect its
operation. While these are explained as thoroughly as possible in this guide, your Omega
dealer or installer is the best source for information about your system.

The Transmitter operates the system only, whereas the Controller both operates the
system, and also responds to signals from the system which alert the user to events
which are occurring with the system. In this respect, the Controller serves as a “pager”,
from the system to the user.
The MARS can be operated by two types of devices-
the 1-Way Transmitter and the 2-Way Controller.

a fresh 12 volt “23A” battery.
The “A/B” slide switch on the side of the
Transmitter may be used to independently
operate a second MARS system.
Pressing and holding the Lock
or Unlock buttons will activate
the system’s remote panic
feature. Another press stops it.

This power doorlock system differs from the negative and positive pulse systems in that there
is no doorlock control unit or relays. In this type of system, the switches themselves supply the
positive voltage directly to the doorlock actuators, and, more importantly, provide the return
ground path. It is important to note that the lock and unlock wires in this system
at chassis ground.

Examine the wires on the back of the switch. (Normally 5 wires will be found
1) One wire will show +12 Volts, regardless of the switch's position.
2) Two wires will be grounded regardless of the switch's position.
3) One wire will show +12 Volts only when the switch is pushed to "Lock".
4) One wire will show +12 Volts only when the switch is pushed to "Unlock".
- When the lock /unlock wires are found, they must be cut one at a time. If the correct wires
are cut the door locking system should not operate from the primary switch.
- Notice that in the diagram the driver's switch is the primary or “Master” switch (in some
vehicles, the primary switch is on the passenger's side). The half of the cut wires which come
from this primary switch are referred to as the "Switch" side. The half of the cut wires which
go to the secondary switch are referred to as the "Motor" side even though the cut is made
between the switches.

2-Way Controller Functions
The 2-Way Controller has
the same four system-operating push buttons as the
Transmitter. Their use is
also identical, as shown.
While the Controller’s Blue
“transmit” light is the same
as the Transmitter’s, the
Controller adds more indicator lights, and a beeper.
These items inform the user,
by sight and sound, of operation confirmations and
notifications of events from
the system.
The Controller also has the A/B
switch, for operating a second
MARS system. Its battery is a
“AAA” penlight battery, and is accessed by sliding the lock tab,
then battery door, from the rear
of the Controller. When the

and orange immediately after the blue “transmit” LED lights.
The 2-Way Controller uses lights and audible chirps to indicate system events. If desired
the chirps may turned off, so that the Controller operates silently. Press the Lock and
Trunk buttons together to toggle the chirps on and off. When the Lock and Trunk buttons
are pressed, the blue light will light followed immediately by either the red light or the green
light. If the red light flashes the chirps are off; if the green light flashes the chirps are on.
Even if the MARS system confirmation chirps are turned off, the controller still has its
chirps, unless they, too, are turned off as described here.
The Receiver Unit
An important part of the MARS system is its Receiver Unit. As its name implies,
the Receiver Unit contains the radio receiver needed for the system to operate
from the hand-held Transmitter or Controller. The Receiver Unit also contains
the Valet / Override Switch and the Status Light. The switch is used to place the
system into Valet Mode (page 12) or to override the alarm if needed (page 14).
The Status Light (actually two) reflects system operations and conditions.
The Receiver Unit is designed for mounting directly on the vehicles’ window glass, which also
gives the system its best operating range. Should
this not be possible or desired, the Receiver Unit
may be mounted in a hidden location, and provisions are made for optional separately-mountable
Valet / Override Switch and Status Light.

Warning: The Positive pulse system can be confused with the 5-wire Reversing Polarity system. This
is because both systems show +12 Volt pulses on the “Lock” and “Unlock” wires when the vehicle’s
switch is pressed respectively. It is critical to identify which system is present, since if +12 Volts is pulsed
into a Reversing Polarity system, which rests at ground, a direct short circuit will occur.
3 main differences between a Positive pulse and a Reversing Polarity system:
1) In a Reversing system the Lock/Unlock wires
rest at ground,
while in a Positive system
operate the vehicle’s on-board doorlocking relays. If the vehicle’s Negative pulse

Operating the MARS system is easy, and basically the same processes when using the
1-way transmitter or the 2-Way Controller. When the Controller is used, the system will
respond back to the user confirming the operation. The Transmitter and Controller both

3 Wire Positive Pulse Systems
This doorlock system is similar to the 3 wire negative pulse system except the doorlock
switches send +12 Volt pulses to operate the doorlock relays/control unit.
Examine the wires on the back of the doorlock switch:
1) One wire will show +12 Volts, regardless of the switch's position.
2) One wire will show +12 Volts only when the switch is pushed to "lock".

Locking the doors with either Transmitter and Controller secures the vehicle, AND arms
the MARS alarm unless the system is in Valet Mode (page 12). Whenever the alarm is
armed, the Status Light in the Receiver Unit will flash, as an indicator and a deterrent.
Should the system detect any violation of a protected zone it will trigger an alarm condition,
which sounds the siren and flashes the parking lights. If the Controller was used to arm the
MARS, the system will also send a signal to the Controller to notify the user.

interrupt can prevent the vehicle’s engine from being started. If the alarm is triggered,
and the user does not disarm it, it will stay triggered for 60 seconds and then automatically
reset back to the armed state, provided that none of the protected zones are violated at that
time. Should there still be a violated zone, the MARS will re-trigger an alarm, and resend
the notification to the pager. This can occur for up to 5 alarm cycles.

This harness, which plugs into the White 3-pin port on the control module, is the power
doorlock outputs by which the MARS operates the vehicle’s power doorlock system (the
vehicle must have existing power doorlocks). The doorlock interface needed to allow the
system to operate the doorlocks will depend upon the type of power doorlocking system
the vehicle is equipped with. The following sections describe typical power doorlocking
systems, which are categorized as “3 Wire Negative Pulse”; “3 Wire Positive Pulse”, and “5
Wire Reversing Polarity” systems.
3 Wire Negative Pulse Systems
This power doorlock system is simplest of all doorlocking systems. A Negative pulse
system will have only three wires at the doorlock switch.
Examine the wires on the back of the doorlock switch:
1) One wire will show Ground, regardless of the switch's position.
2) One wire will show Ground only when the switch is pushed to "Lock".
3) One wire will show Ground only when the switch is pushed to "Unlock".
The lock & unlock wires coming out of the switch operate the vehicle’s doorlock relays or a
control unit with on-board relays, therefore the lock & unlock wires will read Positive voltage,
up to +12 Volts, when the switch is at rest. The correct connection point is between the
switches and the relays. The Red connector's Green and Blue wires can be connected
directly to the vehicle’s Negative pulse system since only a Negative pulse is required to
illuminates the interior light when any of the vehicle’s doors is opened. As a general
40
rule, “Negative” dome lights (Green wire) will have no voltage present and will also
show chassis ground when the doors are opened, and up to 12 volts when the doors are
closed. “Positive” dome lights (Violet wire) have 12 volts present when the doors are opened,
and chassis ground when the doors are closed.
Unlocking the doors with either Transmitter and Controller disarms the MARS
alarm, in addition to allowing access to the vehicle. If the alarm is disarmed
9
while it is triggered, the alarm will have the extra 4 chirps and parking light flashes, but the
Controller will not change to having the 3 chirp and red flashing LED confirmation until
after the alarm resets itself.
Regardless of type, the correct target wire will show this polarity change when any door is
are opened. If the vehicle has delay dome lights, remember to take this into account when
testing the wire. If the pin switch is mounted in the metal structure of the vehicle, and the
dome light goes out when the switch is removed, suspect a grounding-type dome light
system. While the traditional pin switch is mounted in the front door jamb area, also be aware
that many vehicles utilize other types of switch devices to operate the interior lights. Some
have a sliding type of switch and many have the pin or sliding switches in the rear door jamb
area. In addition, some vehicles utilize switches in the doors, either connected to the exterior
door handles or to the latching mechanism. A vehicle which has the dome lights illuminating
when the exterior door handle is lifted is an example of this type of switching system. Also
be aware of vehicles which diode-isolate each door. Typically, this is usually encountered
with dash displays that indicate individual doors being ajar. The proper wire to connect to in
this type of system is the common wire which is routed to the dome light itself.

White wire to the vehicle's 12 Volt parking light circuit as shown in the accompanying
diagrams. The correct wire will show 12 Volts only when the headlight switch is in the
"Parking Light" and "Head Light" positions. This wire can usually be found at the headlight switch, and various other locations within the vehicle, such as the rear body harness
or firewall connector.

The Valet Switch: Valet Mode and Alarm Override
The MARS system has a “Valet Switch”, built into the window-mounted receiver unit, which
serves two important functions:
• To place the system into a “Valet Mode” whereby the alarm cannot be armed, nor can the
remote start function operate. Door lock, unlock and trunk release will still operate.
• To “Override” the alarm function, in conjunction with the ignition key, should the Transmit-
ter or Controller be lost or have a low battery.

This output may be used to arm a factory-installed alarm, or,
( - ) OEM Arm Output
if the vehicle is equipped with a Retained Accessory Power circuit, this output can be used
to “spike” the door pin switch wire, which will turn off the Retained Accessory Power circuit.
To arm a factory alarm after remote start engine run stops, connect the Yellow/Red wire
to the vehicle's factory arm wire. This wire will show Negative polarity when a key is held in
the "lock" position in the door key cylinder. This wire can usually be located in either kick
panel, in the wiring harness from the door, as it is routed between the door key cylinder and
the factory alarm.
To use this wire to turn off Retained Accessory Power, locate a vehicle wire within the
door or doorjamb which shows Negative when the door is open. Should such a wire be
found which is positive, a relay is needed to reverse the Yellow/Red wire’s Negative output
to Positive. The Yellow/Red wire produces a Negative pulse output whenever the system
turns off the engine after it has been remotely started.

To Override the armed alarm: Use the key to turn the vehicle ignition switch “on”, and
within 5 seconds press the Valet Switch 1 time (the default setting), or press it the number
of time that the Coded Override has been programmed for.
Be prepared, as upon entering the vehicle, or upon turning on the ignition, the armed alarm
will trigger, sounding the siren and flashing the parking lights.
After pressing the Valet Switch, the alarm will disarm several seconds later if the entry was
correct. It will not disarm if the Valet Switch was pressed an incorrect number of times.
The factory-set default setting is 1 press to obtain the alarm override, but this is a programmable feature in which can the user can customize a number of 1 to 9 presses of Valet
Switch to achieve the override.
The Override procedure is also with the two forms of Anti-Carjacking protection. How to
custom-program the Coded Override is on page 18, and see page 20 for the description of
the Anti-Carjacking features.
Programming Features
The MARS has a total of 14 “programmable features”; most of these are “operational”
features, some are “installation”-related, and one returns all features to the factory setting.
These features can be changed by very easily by placing the MARS into a “Features Programming Mode” and selecting features with the Valet Switch, and then using the Transmitter/Controller buttons to set the feature as desired. The following chart shows the
Programmable Features, after which are detailed step-by-step programming instructions.
read 1 to 6 volts AC with the engine idling, and will increase with engine speed.
2) Switch the selector slide switch on the MARS control module to the right toward
the 12-pin secondary harness (see pages 46-47 & the markings on the control module).
3) Adjust the tach signal by starting the engine and turning the right adjustment screw on
the control module slowly clockwise until the indicator LED lights solid.
4) Test the operation by remote starting and checking that the indicator LED slights solid.
The starter engagement is long enough for the engine to start, but without grinding. If
needed adjust the crank time by turning the adjustment screw clockwise for more signal
sensitivity and counterclockwise for less.

engines, operates only if programmed (feature #13) and is also polarity-programmable.
Connect the Green/Red wire to the wire in the vehicle which powers the glow plugs, or the
wire which illuminates the “Wait To Start” light on the instrument panel. When connected,
the unit will not engage the starter if the Green/Red wire has +12 Volts; in other words,
using this wire simply delays the unit’s engagement of the starter. If the “Wait To Start”
light in the vehicle has a Negative switching circuit, change the position of the White “Glow
Plug +/- Select” Jumper on the module to reverse the Green/Red wire’s polarity input.

cess. Consider both methods before selecting one to use, and then connect the
Black/Yellow wire accordingly. Either connection method must be performed at
the completion of the installation, after all other wiring connections are made.
Smart Start sensing is more commonly used, for its ease of installation. The unit as
received has Smart Start selected. Smart Start “reads” the vehicle’s battery voltage level
via the Black/Yellow wire to determine engine running status. To use Smart Start:
1) Connect the Black/Yellow wire to constant “Battery” 12 volts. This may done at the
ignition switch harness, or at the battery itself for better sensitivity.
2) Switch the selector slide switch on the MARS control module to the left toward the
module corner (see pages 46-47 and the markings on the control module).
3) Adjust Smart Start by starting the engine and turning the left adjustment screw on the
control module slowly clockwise until the indicator LED starts flashing. Turn the adjustment until the LED is flashing in a consistent and regular manner.
4) Test the operation by remote starting and checking that the indicator LED shows the
same consistent flashing (good voltage signal learned), and that the starter engagement is long enough for the engine to start, but without grinding. Turn clockwise for
more crank time and counterclockwise for less crank time.
Tach Wire sensing is generally more reliable, and preferable in cases were the engine
normally starts inconsistently, or is hard to start . With this method the Black/Yellow wire
reads the engine speed (tach) information directly from a wire in the vehicle. To use the
Tach Wire method:
1) Connect the Black/Yellow wire to the vehicle's tach wire, which is found in the engine
compartment, although in many cases it may also be located inside the vehicle. To use
a multimeter to verify the correct tach wire, set it for AC Volts scale. The correct wire will

How to program the features:16
1) Turn the ignition key “On”, then “Off”.
2) Within 7 seconds press the Valet Switch 5 times.
The Status Lights will flash twice, and if the siren chirps twice.
The parking lights turn on, and stay on while in programming mode.
3) Select the feature to be changed by pressing the Valet Switch the same number of times
as the feature number (example: feature #3 = 3 presses).
The Status Lights will flash the same number as the Valet Switch presses just
entered. The siren also chirps the same number.
Count the number of flashes or chirps to confirm that the desired feature has been
chosen (if needed, reenter the Valet Switch presses).
4) Once the feature number has been confirmed, press the Transmitter/Controller buttons
as follows:
“LOCK” = Feature’s Default 1st setting (
“UNLOCK” = Feature’s optional 2nd setting (

5) Select another feature by again making a new entry of Valet Switch presses
(repeating step 3) and again setting the newly chosen feature with the transmitter (as in
step 4).
Exiting Programming Mode:
Simply allow the MARS to time out of Features Programming Mode by not performing
any programming actions for 15 seconds; or, turn the ignition “On” to exit immediately.
The MARS indicates its exit from Features Programming Mode with 2 short and 1
long Status Lights flashes and the parking lights turning off. If the horn is connected it will have 2 short and 1 long chirps.
About the Programmable Features
The MARS Programmable Features are arranged so that the “operational” features, which
are of user interest, come before the “installation”-related features. The purpose of installation-related features is to adapt the MARS to certain vehicle situations; these are to utilized at the time of the installation only.
• Features #1 through #10 have “daily use” benefits, and may be programmed by the user,
if so desired, to suite their preference or needs.
#
• Features
• Feature #14, “Reset All Features To Default”, quickly and conveniently returns all fea-
tures to their factory settings. This is extremely helpful if there has been a mistake in
programming, or if there is any doubt or confusion of settings, to return them to default.
11 through #13 should be programmed by the installer, not the user!
18
Explanations of the User’s “daily use” Programmable Features:
• Feature #1, “Coded Override”, is used to override a triggered alarm without a Transmit-
ter or Controller, and it also may be used another pair of programmable feature, “Ignition
Activated Anti-Carjacking” and “Door Activated Anti-Carjacking”.
How to program Coded Override:
Place the MARS into Features Programming Mode (page 16) and access Feature #1.
After the Status Light flashes once and the horn chirps once to confirm that Feature #1 is
ready for programming, press the Controller “LOCK” button for each digit of the desired
customized Coded Override, but wait after each single “LOCK” button press for a single
Status Light flash and horn chirp before pressing the button again for the next digit.
When all of the digits have been entered in this fashion, wait for the Status Light and horn
to flash and chirp the complete total number.
Example: for a Coded Override of “3 presses”, programming would be: enter Features
Programming Mode, select “feature 1” (
for
1 flash / 1 chirp

• Feature #2 is “Engine Running Time”. When MARS remotely starts the engine, the
run time before automatic shut-off is adjustable. A 10 minute run time is the factory
setting, with options of 20, 30 or 40 minutes. When programming (see page 16) press
“UNLOCK” for 20 minutes; press “START” for 30 minutes; press “TRUNK” for 40 minutes;
or press “LOCK” for 10 minute setting.

• Feature #3, “Doors Lock/Unlock Upon Ignition On/Off”, has the MARS
automatically lock the doors when the ignition key is turned on, and unlock them
when it is turned off.
19
• Feature #4, “Chirp Confirmation With Arming/Disarming”, offers several forms
of audible confirmation when the MARS is armed or disarming, which also locks and
unlocks the doors. Audible confirmations are made by the electronic siren, or the MARS
may be connected to the vehicle’s horn.
Confirmation with remote doorlocking has the siren chirp once after locking, and twice
after unlocking. Two volume levels are selectable and an “On Demand” operation whereby
the first press of the “LOCK” or “UNLOCK” button is silent, and a second press will produce the confirmation chirp or chirps.
When programming (see page 16) press “UNLOCK” for the On Demand operation;
press “START” to turn off the confirmation chirps; press “TRUNK” for the Quiet chirp; or
press “LOCK” for louder chirp (the factory “Medium” setting).
• Feature #5, “Chirp Confirmation With Starting”, is similar to the previous feature-
when the MARS remote starts the engine it will chirp the siren 3 times; this feature allows
the choice of 3 chirp volume levels (instead of two- “On Demand” chirps can’t be used as
the “START” button operation toggles between “start” and “stop”), or completely turning
off the starting chirps.
The factory chirp setting is “Medium”; when programming (see page 16) press “UNLOCK” to turn the starting chirps off; press “START” for the loud chirps; or press “TRUNK”
for the quiet starting chirps. Press “LOCK” for the factory setting “Medium” starting chirps.
• Feature #6, “Last Door Arming” has the system automatically arm itself every
20
time the ignition is turned off, a door opened, and then closed. With this feature
turned on, upon exiting the vehicle the MARS system will chirp the siren and flash the
parking lights when the door is closed. The Status Lights will start flashing fast, and 390
seconds later the system will arm the alarm and lock the doors, which is indicated by
another chirp, another parking light flash, and the Status Lights slowing to a steady “armed”
flash state. If the 2-way controller was last used to operate the system, it will also chirp
once and flash the red LED when the MARS system does become fully armed.
Anti-Carjacking Features
• Feature #7, “Ignition Activated Anti-Carjacking” is one of two programmable fea-
tures which can assist recovering the vehicle should this type of attack occur. In this
form, the Anti-Carjacking operation automatically starts every time the ignition key is
turned on.
• Feature #8, “Door Activated Anti-Carjacking” is the second Anti-Carjacking pro-
grammable feature. In this form, Anti-Carjacking automatically starts operating if a door
is opened while the ignition key is turned on.
How Anti-Carjacking works: In both forms, Anti-Carjacking is silent for 53 seconds, and
then has a pre-warning stage, randomly sounding the siren, for another 7 seconds. During this 60 second period the driver must press the Valet Switch once to cancel AntiCarjacking.
If not cancelled, at 60 seconds after Anti-Carjacking is activated the siren changes to a
steady output and the parking lights start flashing, and from this point pressing the Valet
Switch will not turn it off. Instead, the ignition must be turned off, turned back on and
and affix the Receiver Module. Carefully route the module’s 5-wire ribbon cable to
thecontrol module; plug the cable into the Black 3-pin port on the rear of the module,
and plug the remaining two connectors into their respective 2-pin ports.
Optional: Should it be desired, an optional separately-mountable Valet Switch and
Status Light are available. The Receiver Module must still be used for its receiver section,
but the Valet Switch and/or Status Light may be placed as desired.

must supply adequate amperage. The most common sources are the battery (+) terminal
or the ignition switch wiring harness. Good reliable connections and use of the included
fuses are a must. Note that some ignition switches have the electrical switch as part of the
mechanical switch; others have the electrical switch lower on the steering column and
connected to the mechanical switch by a linkage. The ignition switch wiring harness is the
best source for these wires, and the Starter, Ignition #1 and Accessory wiring connections.

will show +12 Volts only when the ignition key is in the "Start" position. This wire is also
found in the ignition switch wiring harness (see diagram on previous page). Some vehicles
have a second Starter wire known as a "Cold Start" wire. When this is encountered, two
options are available: program the Yellow/Green wire as a second starter output, or use an
optional relay configured to the 3-pin Red port to energize the second Starter wire (see

wires, then "map out" the installation by locating and noting the target wires in the
vehicle. This will also determine the best location for the MARS control module, which is
mounted upon completion of the installation.
The MARS remote starting unit duplicates the actions that occur within the ignition
switch when you use your key to start the engine. Because of this, most of the main wiring
harness connections will be made at the ignition switch harness. The ignition switch wires
usually are high amperage circuits, which means that high reliability connections must be
made- soldering of all connections is recommended.

Main Module:
The MARS Main Module should be mounted in a location close to the ignition switch
(where many of the wiring connections are made); typically, hidden behind the driver’s
side dash.
Receiver Module:
An essential part of the MARS is the plug-in window mount Receiver Module, which also
contains the Valet Switch and Status Lights. The unit will not operate unless this Receiver
Module is plugged-in. Select a desired mounting location for the Receiver Module; optimum
performance is obtained by mounting this module high and unobstructed on the vehicle’s
glass, such as the windshield behind the rearview mirror. Make sure the glass surface is
clean and free of dust, grease, or debris. Peel the backing off of the adhesive tape
within 5 seconds the Valet Switch may be pressed to in order to stop the Anti-Carjacking operation (it will stop a few seconds after the Valet Switch press). If the
ignition key is turned off, the siren will stop sounding as long as the ignition is off, although the parking lights continue to flash. Turning the ignition key back on, which will be
necessary to stop the Anti-Carjacking by pressing the Valet Switch, will cause the siren to
resume sounding.
Anti-Carjacking cannot be turned by the Controller or Transmitter, and once fully activated, if the Anti-Carjacking is not properly turned off, it will continue to sound the siren
and/or flash the parking lights until the vehicle’s battery is exhausted.
At 90 seconds after activation, the MARS will engage it’s starter interrupt output, so
adding an optional starter interrupt relay to the system will greatly enhance the AntiCarjacking feature, and the chances of recovering the vehicle should it be taken.
Anti-Carjacking can be made even more difficult to defeat with the use of “Coded Override”
(Feature #1). Instead of 1 Valet Switch press to turn it off after fully engaging, multiple
presses must be made. The number of presses, 1 through 9, are chosen and programmed
by the user Even if a customized Coded Override is used, only one Valet Switch press is
needed to cancel Anti-Carjacking before it fully engages at 60 seconds; after that point that
the correct custom Coded Override must be entered to turn off Anti-Carjacking.

• Feature #9, “Unlock Doors With Trunk Release” has the doors unlock automati-
cally whenever the remote trunk release is used. If this feature is turned off (press “UNLOCK” when programming, page 16), the trunk release will still operate when used, but
the doors will not unlock. When this feature is on, the MARS flashes the parking lights
twice, and the siren chirps twice when trunk release is used; if this feature is turned off,
the trunk release operates with 2 Status Light flashes only.
• Feature #10 is “Pulsed or Steady Horn / Siren Output”. This feature’s first

“START” for medium horn pulses; or “LOCK” for default medium horn pulse setting. For
using the electronic siren, program steady output by pressing “UNLOCK” when programming. Do not use the steady output setting for the horn- continuous use will damage it.

The “installation-related” Programmable Features:
Programmable Features #11 through #13 should only be used by the installer. All of these
features program certain aspects of the MARS to match the vehicle into which it is installed. Do not change any of these features once the MARS is installed and properly
configured. The exception would be, if the programmable features are reset by using
feature #14, features #11, #12, and #13 will be returned to the default positions, and if a
different setting than default is required they will have to be reprogrammed to be as the
installer set them.
• Feature #11 is “Starter Cranking Time”, which sets the base starter cranking time
for the Smart Start voltage sensing engine detection method (page 34). When using
Smart Start, a longer starter cranking time may be used for engines which do not start on
the first remote start attempt. Programming choices are: .5 second (“LOCK”, the default
setting); .75 second (“UNLOCK”); 1.25 second (“START”); and 1.5 second (“TRUNK”).
Installation Instructions
27
After reading this manual, start the installation by affixing the WARNING
DECAL to a visible area in the engine compartment!
Do not attempt to install this Remote Car Starter into a manual transmission
vehicle! Doing so could cause serious property damage, personal injury,
and will void all warranties!
Be aware of, and avoid, any airbag circuitry! Due to the fact that an installer
will not be in a normal, upright seated position, severe injury may occur in an
accidental airbag deployment!
The use of a Digital Multimeter (DMM) or Volt-Ohm Meter (VOM) instead of a
standard testlight is required. This can greatly reduce the risk of an accidental airbag deployment or on-board computer damage.
Battery gases are explosive! Avoid sparks and do not smoke while working
near the vehicle's battery!
Always protect wires routed through the firewall from sharp metal edges and
hot parts of the engine! Always fuse positive wires at their source!
Installation Considerations: This entire booklet should be read before starting the
installation. An understanding of which control module wires are to be used and their
functions is essential. Installations will vary from car to car, as some control module wires
are required, while others are optional. Before starting the installation, it should be deter-

• A final point to remember is that neither the MARS-03 controller nor the MARS system in
itself from “receive” to “standby” mode.
the vehicle can receive signals while they are transmitting- allow a couple of seconds for
each controller or system operation to be completed before attempting or expecting
another operation.
• Feature #12 is “Single or Double Unlock Pulse”. The double unlock pulse
is only needed in certain vehicles. Programming settings are single unlock pulse
(“LOCK”) and double unlock pulse (“UNLOCK”).
23
• Feature #13 is “Gasoline or Diesel Engine”. When programming, press “LOCK” for
the “Gasoline” setting. Diesel engines have three options: pressing “UNLOCK” selects
“Monitor Glow Plug Wire”, by which the MARS delays engaging the starter until its glow
plug input wire detects the glow plugs turning off; and two preset delay periods before
starter engagement: 10 seconds (“START”) and 20 seconds (“TRUNK”).
Resetting all of the Programmable Features:
• Feature #14 is “Reset”, and returns all Programmable Features to their factory default
settings. Enter programming mode (page 16), select Feature #14, and press the Controller or Transmitter “LOCK” button. The MARS will acknowledge the “LOCK” input with a
single Status Light flash and siren chirp, and then immediately exit programming mode
with the normal confirmation of 2 short and 1 long Status Light flashes and siren chirps.
Note: When a Programmable Features Reset is used, any feature which needs to be in
a setting different from the default setting will have to be reprogrammed.
Programming Controllers and Transmitters
The MARS can be operated by up to four Controller and/or Transmitters. Replacement or
additional Controllers and Transmitters must be programmed to operate the MARS. The
MARS multi-car operation capability also requires that Controllers and Transmitters be
programmed into the second vehicle’s MARS system with the transmitter’s multi-car switch
in “B” position. Coding Controllers and Transmitters is the same for both types, and
24
is a very easy process.
Any time that Transmitters/Controllers are programmed to operate the MARS, for 48
hours afterward every time that the ignition key is turned “on” the siren will briefly
chirp and the Status Light will flash the number of operating Transmitters/Controllers.
This is the “Unauthorized Transmitter Alert” protection feature.
• Have present all of the which are to operate the MARS. When a Controller or Transmitter
is programmed to the system, any existing ones are erased. Therefore all Controllers and
Transmitters which are to operate the system must be programmed at the same time.
1) Turn the ignition key “On” (and leave it “on”).
2) Within 7 seconds press the Valet Switch 5 times.
The receiver unit’s Status Lights turn on, and the siren chirps once (if connected).
3) Within 15 seconds press the first Transmitter/Controller’s “LOCK” and “UNLOCK”
buttons together.
The MARS will acknowledge the transmission by momentarily turning off the
Status Lights and chirping the siren 1 time.
4) Within 15 seconds press the next transmitter’s “LOCK” and “UNLOCK” together.
The Status Lights turn off and the siren chirps once.
Repeat this action for each remaining transmitter.
Exiting Programming Mode: Simply allow the MARS to time out of the programming
mode, by not transmitting for 15 seconds; or, turn the ignition “Off” to exit immediately.
The MARS indicates its exit from programming mode by turning off the
Status Lights and sounding a series of siren chirps.
• When programming Controllers/Transmitters for two vehicles, program one system with
the A/B switch set for “A”, and program the second vehicle with the switch set to “B”.

Other MARS Operational Notes
• The MARS system in the vehicle will not transmit a signal to operate the Controller unless a Controller was last used to operate the system. Example: if the 1-way Transmitter
is used to arm and lock the doors, the system will not transmit a signal which will cause
the controller to chirp and flash its indicator LED. Also, should multiple Controllers be
programmed to operate the system, the system will send its confirmation signal to only
one Controller- the last one used.
• When the MARS system does send a signal to the Controller, a few seconds is needed
for this “handshake” to occur. If the system is operated in a rapid fashion, as in quickly
repeating lock and unlock cycles, the Controller will not have time to receive the signal
from the system, and therefore stop responding and reporting the system’s status. Normally operating the system corrects this symptom.
• When the Controller receives a signal, it will stay in receive mode to keep “listening” for
a signal for a few seconds, even while it is performing the confirmation action (i.e.- chirping and lighting its LEDs). If the user tries to immediately use the Controller, the first
button press will only switch off the “receive” mode (the blue LED will not light). To send
a transmission, the button must be released and then it can be pressed again. Or, wait
a few seconds after the Controller starts the confirmation action to allow it to switch
