When Monitored:
Every 7 msec. Conditions: 1) Engine speed greater than 500 RPM. 2) Battery voltage greater than 10v but
less than 16v.
Set Condition:
CAN C bus messages not received for 10 seconds.
Theory of Operation
Some NGC controllers communicate with other controllers over the CAN C bus. The transmission controller contin-
uously monitors the bus activity and receives the messages it needs. The CAN C bus is also used to communicate
transmission MIL status to the Engine Controller, therefor if the Engine Controller is unable to communicate with the
Transmission Controller, the Engine Controller will light the MIL.
Diagnose the U0002 CAN C BUS OFF PERFORMANCE as the U0001 CAN C BUS CIRCUIT test in 8-ELEC-
TRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING for diagnostic procedures and for
further possible causes.
