Power Distribution: Overview Chrysler Crossfire I

DESCRIPTION

This article covers the various standard and optional Power Distribution components used on this model. Refer to SYSTEM WIRING DIAGRAMS . The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

OPERATION

The power distribution system for this vehicle is designed to provide safe, reliable, centralized and convenient to access distribution of the electrical current required to operate all of the many standard and optional factory-installed electrical and electronic powertrain, chassis, safety, comfort and convenience systems. At the same time, these systems were designed to provide centralized locations for conducting diagnosis of faulty circuits, and for sourcing the additional current requirements of many aftermarket vehicle accessory and convenience items.

These power distribution systems also incorporate various types of circuit control and protection features, including

1. Fuses
2. Fuse cartridges
3. Fusible links
4. Automatic resetting circuit breakers
5. Relays
6. Flashers
7. Timers
8. Circuit splice blocks

The power distribution system for this vehicle consists of the following components

1. Engine Fuse Block
2. Underhood Accessory Fuse Block
3. Illumination Control Module
4. Relay Control Module

Following are general descriptions of the major components in the power distribution system. Refer to the owner's manual for more information on the features, use and operation of all of the power distribution system components.

All of the electrical current distributed throughout the vehicle is directed through the Engine Fuse Block. The Engine Fuse Block houses three maxi-type bolt in fuses. The Engine Fuse Block is located in front of the control module box, next to the windshield wiper solvent fill tube.

All of the current from the battery and the generator output enters the Engine Fuse Block through the cable and eyelet that are secured with a nut to the Engine Fuse Block B(+) terminal stud located on one end of the Engine Fuse Block housing. The Engine Fuse Block terminal stud cover is unlatched and opened or removed to access the Fuses.

3. Remove the nuts and the electrical leads to the engine fuse block.
4. Close the lid to the engine fuse block.
5. Push the tab at the front of the engine fuse block box and remove it from the vehicle.

The Relay Control Module controls many of the vehicle relays. The Relay Control Module is located inside the control module box. The Relay Control Module can not be serviced and it must be replaced as a unit.

The Relay Control Module is a solid state device containing the following internal relays.

1. Air Pump Relay
2. Engine Control Relay
3. Traction System Relay
4. Horn Relay
5. Fuel Pump Relay

Scheme 104

1. Disconnect and isolate the negative battery cable.
2. Open the lid to the control module box.
3. Move the wires away to the side of the box to access the clip (1) that holds the relay control module in the control module box.
4. Push the clip (1) back away from the relay control module and lift the relay control module out of the control module box.
5. Remove all of the relay harness connectors from the relay control module.

The Underhood Accessory Fuse Block houses many of the fuses for the vehicles electrical system. The Underhood Accessory Fuse Block is located on the left side of the engine compartment just in front of the brake booster. The Underhood Accessory Fuse Block can not be serviced it must be replaced as a unit.

All of the circuits entering and leaving the Underhood Accessory Fuse Block do so through separate wires. There are NO separate wiring harness connectors that connect to the Underhood Accessary Fuse Block. Each circuit is connected individually to the Underhood Accesssory Fuse Block, and held in place by the use of retention combs.

Scheme 105

1. Disconnect and isolate the negative battery cable.
2. Remove the lid to the underhood accessory fuse block.
3. Push the front of the underhood accessory fuse box forward releasing the tabs (1) on the underhood fuse block.
4. Pull the underhood accessory fuse block out of the box and remove all of the underhood accessory fuse block harness connectors.

The Fuse Block is part of the Illumination Control Module. A knob on the face of the module controls the exterior lighting functions. The exterior lighting and headlamp switch portions of the Illumination Control Module cannot be adjusted or repaired. If faulty or damaged, the entire module assembly must be replaced as a unit. (Refer to ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/HEADLAMP SWITCH - REMOVAL) .

The Fuse Block on the side of the Illumination Control Module houses the Fuses for the following

1. Fuse 2. Brake Lamp
2. Fuse 3. Right High Beam/High Beam Indicator Lamp
3. Fuse 4. Reverse Lamp/Turn Signal Lamp/Rear View Mirror
4. Fuse 5. Left High Beam
5. Fuse 6. Right Low Beam
6. Fuse 7. Right Parking/Tail Lamp Side Marker
7. Fuse 8. Left Low Beam
8. Fuse 9. Fog Lamp
9. Fuse 10. Left Parking/Tail Lamp Side Marker
10. Fuse 11. License Plate/Instrument Cluster Lighting/Symbol Lighting
11. Fuse 12. Rear Fog Lamp (Export Only)
