Pinpoint Test Av: Abs (Anti-Lock Brake System) Module Communication Concern With GSM (Gear Shift Module): Notes
Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the GSM sends messages to the GWM over the HS-CAN2, the GWM relays these messages to the ABS module over the FD-CAN. If the ABS module does not receive these messages within the specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be due to a GSM failure, a circuit failure on the CAN or an excessive load on the network. For information on the messages sent to the ABS module by the GSM, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
