Normal Operation and Fault Conditions
With the ignition ON, the IPMB sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within the allotted time frame, the module sets a DTC. This can be due to an IPMB 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 IPMB, refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article.
