U0002 CAN C BUS OFF PERFORMANCE

For a complete wiring diagram, refer to the Wiring Information. Electrical Diagrams

Theory of Operation

The NGC controller communicates over the CAN C bus and continuously monitors bus activity. If the NGC is unable to communicate with the CAN Bus, a DTC will set and the NGC will illuminate the MIL.

- When Monitored:
Every 7 msec with:

1) Engine speed greater than 500 rpm.

2) Battery voltage between 10 and 16 volts.

- Set Condition:
CAN C bus messages are not received for 10 seconds.

Diagnose the U0002 CAN C BUS OFF PERFORMANCE as the U0001 CAN C BUS CIRCUIT.

For communication diagnostic procedures and other possible causes refer to DTC Based Diagnostics and Non DTC Based Diagnostics.
