Electronically Controlled Clutch (ECC)

U0001-CAN C BUS

For a complete wiring diagram Consult Diagrams/Electrical.

Theory of Operation

The ABS communicates with other controllers over the CAN C bus. The AWD Module continuously monitors the bus activity and receives the messages it needs. The CAN C bus is also used to communicate AWD Control Module MIL status to the Engine Controller, therefor if the Engine Controller is unable to communicate with the AWD Control Module, the Engine Controller will light the MIL.

- When Monitored: Ignition run time is greater than 1 second. Battery voltage between 10 and 16 volts. Engine run time greater than 3 seconds.
- Set Condition:
The PCM loses communication over the CAN C Bus circuit. The circuit is continuously monitored. One Trip fault.
