Normal Operation And Fault Conditions

With the ignition ON, the TBM sends messages to the ABS module over the MSCAN through the GWM. If the ABS module does not receive these messages within the specified time frame, the module sets a DTC. This can be due to a TBM failure, a circuit failure on the GWM or an excessive load on the network. For information on the messages sent to the ABS module by the TBM, refer to the Description and Operation in the  Anti-Lock Brake System (ABS) and Stability Control  article.
