Pinpoint Test AU: Abs Module Communication Concern With AWD Module
Normal Operation and Fault Conditions
The AWD module may also be known as the TCCM.
With the ignition ON, the AWD module sends messages to the ABS module over the FD-CAN. If the ABS module does not receive these messages within the allotted time frame or if the messages contain invalid data, the module sets a DTC. This can be due to a AWD module 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 AWD module, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
