With the ignition ON, the PSCM sends messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the PSCM, refer to the Network Message Chart in Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
