C2315-00-ACC DISABLE DUE TO PCM FAULT

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuously monitored with the engine running and the Adaptive Cruise Control (ACC) Module in normal mode.

- Set Condition:
Normally when an active Diagnostic Trouble Code (DTC) is set in the Powertrain Control Module (PCM). May also set if engine is operated at RPM limit (e.g. driver performing wide open throttle [WOT] maneuvers). The ACC module will disable the ACC system and the ACC UNAVAILABLE message will display in the Electronic Vehicle Information Center (EVIC). Once the DTC changes from active to stored, the ACC system will return to normal operation. This DTC will clear after the ACC Module sees 100 consecutive key cycles with the DTC stored.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.
CHECK FOR DTCs IN PCM
1. Turn the ignition on.
2. Using a scan tool, read PCM DTCs.

Are any DTCs present?

Yes

- Diagnose and repair the DTC(s). Testing and Inspection.

No

- DTC set due to engine operated at RPM limit. Using the scan tool, clear ACC module DTCs.
- Perform the ACC MODULE VERIFICATION TEST. Adaptive Cruise Control (ACC) Verification Test.
