Normal Operation and Fault Conditions
On vehicles equipped with a 3.2L engine, the TCM is a separate module from the PCM. With the ignition ON, the TCM sends messages to the ABS module over the HS-CAN. If the ABS module does not receive these messages within the specified time frame, the ABS module sets DTCs. This can be due to a TCM failure, a circuit failure on the HS-CAN or an excessive load on the network. For information on the messages sent to the ABS module by the TCM, refer to the Description and Operation in ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL .
