Pinpoint Test AE: Abs Module Communication Concern With PSCM
Normal Operation and Fault Conditions
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 the allotted time frame or if the messages contain invalid data, the module sets a DTC. This can be due to a PSCM 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 PSCM, refer to the Network Message Chart .
