- When Monitored:
Continuously monitored with the engine running, and the ACC Module in normal mode.
- Set Condition:
A ready conflict between the ACC module and ESP system has occurred. The ACC module will disable the Adaptive Cruise Control (ACC) system and the ACC OFF message will display in the CCN. Once the DTC goes to stored, the ACC system will return to normal operation. The DTC will be cleared after the ACC Module sees 100 consecutive key cycles of the STORED DTC.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
