AC9 CHECK FOR CORRECT GWM (GATEWAY MODULE A) OPERATION
Ignition OFF. Disconnect and inspect all GWM connectors and related in-line connectors. Repair:
corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary
Reconnect the GWM connector and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new GWM. REFER to: Gateway Module A (GWM) (418-00 Module Communications Network, Removal and Installation). |
|---|---|
No | The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. |
No High Speed Controller Area Network 1 (HS-CAN1) Communication, All Modules Are Not Responding
Refer to Wiring Diagrams Cell 14 for schematic and connector information.
Normal Operation and Fault Conditions
The HS-CAN1 modules communicate with the diagnostic scan tool directly through the DLC circuits. REFER to: Communications Network (418-00 Module Communications Network) .
