Troubleshooting Tools
TROUBLESHOOTING TOOLS

When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below.

- - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit.Jumper Wire

WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERYFEED AND GROUND.

- Voltmeter

- This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead tothe positive side of the circuit.

CAUTION:

Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a or greater impedance.10 megohm

- Ohmmeter

- This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean goodcontinuity or a shorted circuit.

CAUTION:

10 megohm

Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter witha or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicleelectrical system can cause damage to the equipment and provide false readings.

Probing Tool

- Probing Tools 6807

- These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package and insert itinto the terminal being tested. Use the other end of the tool to insert the meter probe.

Troubleshooting Wiring Problems

When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check fornon-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-onitems are not the cause of the problem.

1. Verify the problem.

2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams.

3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the
diagnosis will continue.

4. Isolate the problem area.

5. Repair the problem.

6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Keyless Entry Module: Description and Operation
ENTRY MODULE

The Viper Coupe and Roadster utilize an Entry Module (EM). In 1996 this system replaced the prior years Vehicle Theft Alarm and Remotekeyless Entry modules. The module is located on the left side of the transmission tunnel, above the knee bolster. It is secured with a rubber strap. Itcontains a 32-way and two 6-way connectors. There is a green six way connector and a black six way connector. The module is connected to theCCD bus and transmits the "OK to run" message to the PCM when the theft alarm function is not tripped. It also receives the vehicle speedmessage from the bus and through a hardwired backup circuit.

The Coupe and Roadster will use electric door latches to accomplish opening and closing of the vehicle doors and electronics to accomplish thelock function that was typically performed with linkage inside the door. The system utilizes electric latches inside the door and micro switchesboth inside and outside the vehicle. These switches are inputs to the EM and if the conditions are correct, the EM will unlatch the doors. The lockfunction is simply the ignoring of the switch inputs that would normally cause the EM to open the doors. There is no mechanical lock linkageinside the door. This results in fewer moving parts and problems associated with packaging the linkage mechanisms.

The Entry Module provides remote keyless entry functions as well as vehicle theft alarm functions, electric locking/unlocking and the opening orpower unlatching of the doors. The Coupe and Roadster will power unlatch the doors based only on inputs from the switches on the inside or theoutside of the vehicle. The unlock button on the fob will not power unlatch the door. It also allows for the rolling lock feature, the only differencefrom other rolling lock systems is that specific throttle angle is not required for the locks to actuate. It is strictly a speed based system.

8 mph (1.3)

The inside and outside door handles control micro switches that are the inputs to the EM. Located below the inside door switches are the lockrocker switches with LED indicators. The LED lock indicator informs the driver and passenger of the lock status of the doors. If the light is ON,the doors are unlocked. Once the vehicle is started and driven approximately the doors will automatically lock and the LED will beextinguished at this time. The rolling lock feature cannot be disabled. If there is no activity for approximately one minute (input to the EM) and thekey is in the "ON" or "OFF" position, the LED will be turned oft to reduce battery draw.

5 mph

The driver and passenger lock switches are wired in parallel and form one input to the EM. When the EM receives a lock input, both doors arelocked. When an unlock signal is input to the EM, both doors are unlocked. If the key is ON, and an inside door handle input is seen and vehiclespeed is below , both doors will be unlocked (and the door's handle that was actuated will be power unlatched). The lock switches are amomentary contact rocker type switch and either switch will lock or unlock both doors. In case of an electrical failure that would render the EMsystem inoperable, there is an emergency mechanical release for the door located in the "B" pillar area of the door. This can be accessed throughthe liftglass area from outside the vehicle.

5-10 seconds

The key fobs are unique to Viper and utilize a rolling code system. The rolling code feature changes a portion of the key fob message each time itis used. The key fob message and the receiver message change together. Under certain conditions with a rolling code system, the receiver andtransmitter can fall out of synchronization. By pressing the lock and unlock buttons together, and holding until the horn chirps, the system willre-synchronize. The system will take to respond with a horn chirp and normal operation resumes. This is not the same asprogramming a key fob.

60seconds

The system will accept up to four fob codes and the system can be programmed with either the DRB III or by connecting a programming wire toground and placing the module in programming mode. If the system is set up for programming, all key fobs for this vehicle must be programmedat the same time. When the module is placed in the program mode, all previous information from the transmitters is erased and no information iswritten there until the system recognizes a valid key fob. Pressing both lock and unlock buttons on the key fob at the same time will cause thesystem to respond with a horn chirp after approximately ten seconds. Then any other transmitters may be programmed. There is a time out after of inactivity (no further transmitters recognized). If the system times out, it will have to be returned to the programming mode with theDRB III or by disconnecting and re-connecting the green programming wire located near the module connectors. The DRB "Theft Alarm MonitorScreen" contains information about how many fobs have been programmed and if a valid fob message has been received. The horn chirp featurecan not be disabled.

The security portion of the module performs typical security functions. The system can be actively armed by pressing the lock button on the keyfob. The system responds with a single horn chirp, if the message is from a valid (programmed) key fob. This information can also be accessed onthe VTSS monitor screen with the DRB III. The system will passively arm if the ignition is turned OFF and the key is removed, the hood and liftglass (coupe) are closed, and a door is open. Pressing the lock button on the door and closing the door will start a arming period. Thesecurity LED will turn ON during the arming process and the horn will chirp on completion of the arming process. The security LED will thenflash at a 10% duty cycle. The system can only be disarmed with a programmed key fob.

2.5 minutes

18 minutes 18 minutes

When the alarm is tripped, the park lamps and the horn will flash indicating that the vehicle has been tampered with. The alarm can be tripped byopening doors, hood, liftglass (coupe) or turning the ignition ON. Once tripped, the alarm will sound for . The park and tail lamps willflash for approximately . The PCM will not allow the engine to start. If the EM has been tripped and have passed, the hornwill chirp 3 times upon unlocking with the key fob to alert the driver that a theft condition may have taken place. Normal disarming with the keyfob will result in two sort horn chirps.

Coupe

The only way to access the driver compartment of the vehicle once it is locked, (without setting OFF the alarm) is with the key fob. There is anexterior lock cylinder for the lift glass, that allows opening with the key. This cylinder is not equipped with a disarm function. If the liftglass isopened with the key when the alarm is armed, it will set OFF the alarm. There is a liftglass ajar switch that mounts on the left gas prop (on the

coupe). When the liftglass is opened, the outer shell of the gas prop allows a micro switch to close and the liftglass ajar circuit is grounded. TheEM monitors this circuit and knows the glass is open. If the liftglass is broken, the prop will extend and trip the alarm. By utilizing a prop switch inthis manner, the vehicle is protected against opening or breakage of the liftglass. The roadster trunk latch and key cylinder are not protected by thetheft system. Opening of the trunk when the theft alarm is armed will not cause it to be tripped.

5-10 seconds

The key fobs are unique to Viper and utilize a rolling code system. The rolling code feature changes a portion of the key fob message each time itis used. The key fob message and the receiver message change together. Under certain conditions with a rolling code system, the receiver andtransmitter can fall out of synchronization. By pressing the lock and unlock buttons together, and holding until the horn chirps, the system willre-synchronize. The system will take to respond with a horn chirp and normal operation resumes. This is not the same asprogramming a key fob.

The system will accept up to four fob codes and the system can be programmed with either the DRB III or by connecting a programming wire toground and placing the module in programming mode. If the system is set up for programming, all key fobs for this vehicle must be programmedat the same time. When the module is placed in the program mode, all previous information from the transmitters is erased and no information iswritten there until the system recognizes a valid key fob.

The DRB "Theft Alarm MonitorScreen" contains information about how many fobs have been programmed and if a valid fob message has been received. The horn chirp featurecan not be disabled.

Diagnostics

The EM system is fully addressable with DRB III and it is the recommended method for diagnosis. The EM system does not display anyDiagnostic Trouble Codes. All of the input switches to the EM can be read with DRB under the I/O screen. The doors can be unlatched with theDRB under actuator tests. If the inputs are OK and the outputs can be cycled with the DRB, the problem is usually the Entry Module.

Connector and Splice Identification

The connector and Splice numbering used in the vehicle has a letter prefix to identity what harness the connector/splice is located in. A list of these letterdesignations follows:

- B - Body or EDW harness

- C - Dome harness

- D - Door harness

- E - Engine harness

- F - Fuel rail harness

- J - Jumper harness

- L - Liftgate harness

- P - Instrument panel harness

- S - Seat harness

- T - Trailer tow harness

When looking at a splice reference the alpha code for what harness the splice is located in will come first, then an S to indicate a splice, and finally thesplice number. An example of this would be ESO2.

- E - Indicates splice is in the engine harness

- S - Indicates a splice

- 02 - Indicates what splice it is in harness

Wire Color Code Chart

Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire and color. The color is shownas a two-letter code, which can be identified by referring to the Wire Color Code chart. If the wire has a tracer and it is a standard color, an asterisk willfollow the main wire color. If the tracer is non-standard, the main wire color will have a slash after it, followed by the tracer color.(/)

Keyless Entry Module: Diagnostic Aids

Intermittent and Poor Connections

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a sticking component or relay to cause aproblem. Before condemning a component or wiring assembly check the following items.

- Connectors are fully seated

- Spread terminals, or terminal push out

- Terminals in the wiring assembly are fully seated into the connector/component and locked in position

- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem

- Damaged connector/component casing exposing the item to dirt and moisture

- Wire insulation that has rubbed through causing a short to ground

- Some or all of the wiring strands broken inside of the insulation covering.

- Wiring broken inside of the insulation

Troubleshooting Tests

Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problemssection.
