Electronically Controlled Clutch (ECC)

U0141 LOST COMMUNICATION WITH FCM (TIPM)

For a complete wiring diagram Refer to Diagrams/Electrical. Electrical Diagrams


Theory of Operation


Some NGC controllers communicate with other controllers over the CAN C bus. The AWD Control Module continuously monitors the bus activity and receives the messages it needs. The CAN C bus is also used to communicate PCM 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:

Every 7 msec. Conditions: Battery voltage greater than 10v but less than 16v.

- Set Condition:

CAN C bus messages not received for 10 seconds.
