When VRS is enabled and the vehicle is stolen or carjacked, VRS sounds the siren and flashes the parking
lights to persuade the thief to abandon the vehicle, and when the ignition is turned off, activates the starter
disable to prevent the engine from restarting.
To arm VRS:
• Perform the silent mode arm command while driving, or while the ignition is turned ON. The siren
chirps and parking lights flash once to confirm arming. The arm LED and beeps play to confirm
arming.
Note: If Valet mode is ON, the LED and fault tone plays, exit Valet mode before arming VRS.
• Once armed, VRS triggers if any door is opened then closed while the ignition is ON, and if the
vehicle is parked while armed, VRS triggers when driving resumes. See trigger description below.
• When triggered, the Control Center LED begins flashing after fifteen seconds. Within 45 seconds
perform the silent mode arm command to disarm VRS.
Note: If not disarmed, the siren begins chirping for 60 seconds and then becomes a constant siren blast
with flashing parking lights for several minutes. This output will continue and be repeated each time the
ignition is turned ON until VRS is disarmed.
To disarm VRS:
• Perform the silent mode disarm command on the remote anytime before VRS has been triggered, or
within one minute after it has triggered and before the siren begins to chirp.
Note: If not disarmed before the siren begins to chirp, the emergency override procedure must be used
to disarm VRS. (see owners guide for override procedure).

Reset and Deletion
If a feature needs to be reset or the remote controls need to be deleted, use the following procedure:
1. Open a door.
2. Turn the ignition to the ON position.
3. Within 10 seconds, press and release the Control Center button 2 times if you want to delete remote
controls or 3 times to reset features. These function steps are described next.
• Delete remote controls: This feature erases all remote controls from the memory of the security system.
This is useful in cases when a customer’s remote is lost or stolen.
Note: This does not reset the programmed features of the security system.
• Reset Features: This resets all features of the security system to the factory default settings.
Note: This feature does not delete the remote controls from the security system.
4. Once you have selected the function step, press the Control Center button once more and hold it. The
LED flashes and the siren chirps to confirm the selected functional step. Do not release the Control
Center button
5. While holding the Control Center button, press the button on a programmed remote control. The siren
chirps to confirm that the remote controls have successfully been deleted or the features have been reset.
6. Once the feature is reset, the Control Center button can be released.
The system stores the last six full triggers in memory. These are not erasable. To access long term event history:
1. With the ignition OFF, press and hold the Control Center button.
2. Turn the ignition ON.
3. Release the Control Center button.
4. Within 5 seconds, press and release the Control Center button. The status LED flashes in groups
indicating the last six zones that triggered the unit for 1 minute or until the ignition is turned OFF (indicated
in the order of most recent first to oldest last). Refer to Table of Zones for trigger information.
Note: The Warn Away triggers are not stored to memory and is not reported.
Table of Zones
A zone is represented by the number of status LED flashes used by the system to identify a particular type of
input.

Troubleshooting: Alarm
Shock sensor doesn’t trigger the alarm:
1. Was the onboard shock sensor adjusted before the brain was mounted? If so re-adjust the sensor.
2. Has the onboard shock sensor been turned OFF? The sensor has the ability to be turned OFF when
adjusting.
3. Has the NPC system been triggered? If so, you hear 5 chirps when disarming. To check this, turn the
ignition key ON and OFF to clear the NPC memory, and then retest the shock sensor. For a detailsed
description of NPC, see Nuisance Prevention Circuitry section of the owners guide.
Door input does not immediately trigger full alarm. Instead, chirps are heard for the first 3 seconds:
• That’s how the progressive two-stage door input works! This is a feature of this system even if the door
is instantly closed again, the progression from chirps to constant siren continues.
Closing the door triggers the system, but opening the door does not:
• Have you correctly identified the type of door switch system? This happens often when the wrong
door input has been used.
System does not passively arm until it is remotely armed and then disarmed:
1. Is passive arming programmed ON?
2. Are the door inputs connected? Is the 12-pin Blue wire connected to the door trigger wire in the
vehicle? Either the 12-pin Green wire or Violet wire should be used instead.
Door input does not respond with the progressive trigger, but with immediate full alarm:
• Does the Status LED indicate that the trigger was caused by the shock sensor? (see Table of Zones
section of this guide.) The shock sensor, if set to extreme sensitivity, may be detecting the door
unlatching before the door switch sends its signal. Reducing the sensitivity can solve this problem.
There are eight major types of door lock circuits not including door lock systems that are centrally controlled
through the vehicles data bus system.
Note: In most data bus systems door locks can be controlled with a Directed interface module.
• Type A: Three wire (+) 12V pulse controlling factory relays/module.
• Type B: Three wire (-) ground pulse controlling factory relays/module.
• Type C: Directly wired to the switch (5-wire reversing polarity switches) with no external relays/
modules.
• Type D: Aftermarket actuator driven systems. These include central locking systems that don’t have an
actuator in the drivers’ door but has actuators in the remaining doors of the vehicle.
• Type E: One wire electronically activated vacuum system (typically found in older Mercedes Benz
vehicles). This typically requires the door lock pulse output duration to be changed on the system.
• Type F: One wire door lock system that requires the wire to become an open circuit (break the wire)
to lock the vehicle doors and requires a (-) pulse to unlock the vehicle doors.
• Type G: (+) one wire multiplex door locks. The vehicle requires a (+) 12V pulse through resistors to
control the locks in the vehicle.
• Type H: (-) one wire multiplex door locks. The vehicle requires a (-) ground pulse through resistors to
control the locks in the vehicle.
The following diagrams will show how to connect this system to the different types of door lock types.
Type A: (+) 12v controlling factory relays/modules:
With this type of circuit the door lock wires will test (+) 12v respectively when pressing Lock or Unlock from
the switch.

With this type of circuit the door lock wires will test (-) ground respectively when pressing Lock or Unlock from
the switch or for factory alarm arm/lock and disarm/unlock, you will test the wires while turning the key in
the driver door key cylinder.
Note: For factory alarm disarm/unlock the system may need to be programmed to have a double pulse
output when unlocking (see Door Lock Pulses in Feature Programming).

Type C: Direct wired reversing polarity
With this type of circuit, there are typically 4 or 5 heavy gauges wires that go to the switch. One wire feeds
(+) 12v to the switch, the other feeds a (-) ground to the switch while the remaining wires will go directly out
to the actuators. The actuator wires will rest at ground, therefore you must ensure that the White/Black and
Brown/Black wires are connected to the switch side of the cut wire, if this is not done you will send (+) 12v
to ground possibly damaging the module or the switch.
With this setup you are either adding actuators to a vehicle without a keyless entry or power door lock option
or you may have a Type D Vehicle with a central locking system (all doors are controlled when manually
locking the driver front door) this will only require the installation of one actuator in the driver door.
Note: If installing more than two actuators it is recommended to use external relays to support the current
demands of three or more actuators.

Door Lock Switch
In most cases the door lock output duration will need to be extended to a 3.5 second pulse (see Door Lock
Output Duration in Feature Programming). This wire will test (-) ground when the doors are locked and (+)
12v when the doors are unlocked.
Note: The Violet jumper wire at the fuse holder between the Pin 1-Violet wire and the Pin 4-Violet/Black wire
of the door lock harness must be cut!
Type F: One wire door lock system
This type of system requires an open circuit to lock the doors and a (-) pulse to unlock the doors. The wire will
test as an open circuit when locking the vehicle doors and will test as a (-) ground when unlocking the vehicle
doors (these can be reversed in some vehicles).
Note: The Violet jumper wire at the fuse holder between the Pin 1-Violet wire and the Pin-4 Violet/Black wire
of the door lock harness must be cut!
This type of system handles the door lock control on one wire utilizing different (+) 12v voltages to handle the
lock and unlock function or factory alarm arm/lock and factory disarm/unlock function in the vehicle. The
door lock switch, driver door key cylinder or BCM may contain one or two resisters to achieve the required
voltage to control the vehicle door lock system.
Single resistor type:
If one resistor is used in the door lock switch/key cylinder, the wire will show (+) 12v in one direction and less
than (+) 12v when operated in the opposite direction.
Dual resistor type:
If two resistors are used in the door lock switch/key cylinder, the wire will show less than (+) 12v in either
direction.
This type of system handles the door lock control on one wire utilizing different (-) ground voltages to handle
the lock and unlock function or factory alarm arm/lock and factory disarm/unlock function in the vehicle. The
door lock switch, driver door key cylinder or BCM may contain one or two resisters to achieve the required
voltage to control the vehicle door lock system.
Single resistor type:
If one resistor is used in the door lock switch/key cylinder, the wire will show (-) ground in one direction and
resistance to ground when operated in the opposite direction.
Dual resistor type:
If two resistors are used in the door lock switch/key cylinder, the wire will show resistance to ground when
operated in either direction.

Determining the Proper Resistance Values:
Most vehicle information documents will offer the resistance values required to operate the factory door locks
in the vehicle, however there are times when the information is not available or a different resistance value
is required. To determine the resistance values that are required to control the lock/arm and unlock/disarm
functions in the vehicle you will need to use a digital multimeter. Set for measuring resistance (ohms)
1. Locate the lock/arm or unlock/disarm wire in the vehicle.
2. Once the correct wire is located, cut it in half and set your digital multimeter to ohms.
3. Place one lead of the meter to (+) 12v or a reliable (-) ground (depending on (+) or (-) multiplex door lock
system) and the other lead of the meter to the switch side of the cut wire in the vehicle. Press and hold the
switch or turn the key in the door to the lock position. Your meter will display the proper resistance for that
function. Repeat the process, however you will be pressing the unlock side of the switch or turning the
key in the door to the unlock position and your meter will display the proper resistance for that function.
4. Once the proper resistance(s) have been found use the applicable Type G or Type H diagrams for wiring
information.
Note: Not all multiplex door lock circuits for both lock/arm and unlock/disarm will need resistors for both
operations. If your meter shows 0 resistance in either direction, then a resistor is not required for that operation.
