Pinpoint Test BQ: Abs Module Communication Concern With The IPMA
Normal Operation and Fault Conditions
With the ignition ON, the IPMA 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 circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the IPMA, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
