Normal Operation and Fault Conditions
With the ignition ON, the TCCM sends messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within the specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be due to a TCCM failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the TCCM, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
