Pinpoint Test BP: Abs Module Communication Concern With GWM
Normal Operation and Fault Conditions
With the ignition ON, the GWM 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 GWM 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 GWM, refer to the Network Message Chart .
