All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition.

Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a componentindicates that the component being shown is not complete. Incomplete components have a reference number to indicate the sheet where the component isshown complete.

It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a shortpiece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only.

Circuit Function

Circuit Identification Code Chart

All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to theCircuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models.

Fasteners

Shock Tower To Spring Minimum Clearance Area

CAUTION:

NO

At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place ofan original plastic clip. Also, holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into thestrut tower.

Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of thespring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog.

Fuses

CAUTION:

When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a ratingother than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.

Notes, Cautions and Warnings

Additional important information is presented in three ways: Notes, Cautions, and Warnings.

NOTES

are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate differentconditions that may appear on the vehicle. For example, an up-to and after condition.

Positive Temperature Coefficient

Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids.

Positive Temperature Coefficient Symbol

A special symbol is used to identify these in the wiring diagrams.

Section Identification

Wiring Diagram Section Identification

The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires,connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. Itcan, however, be shown partially in another group if it contains some associated wiring.

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

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.

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 thecoupe). 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.

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.

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.

Fasteners

Shock Tower To Spring Minimum Clearance Area

CAUTION:

NO

At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place ofan original plastic clip. Also, holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into thestrut tower.

Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of thespring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog.

Fuses

CAUTION:

When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a ratingother than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected.

Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the

junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids.

Positive Temperature Coefficient Symbol

A special symbol is used to identify these in the wiring diagrams.

Section Identification

Wiring Diagram Section Identification

The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires,connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. Itcan, however, be shown partially in another group if it contains some associated wiring.

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 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

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.

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 thecoupe). 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.

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.
