Normal Operation and Fault Conditions
The TCCM expects to receive network data from other modules on HS-CAN2. The TCCM will set a DTC when it receives invalid or incomplete messages from a module. A suspect module may send an invalid messages is there is a fault with one or more input sensors. Incomplete or corrupted messages typically result from high network traffic preventing the complete message from being received within the calibrated time limit.
