- 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 Initial Inspection and Diagnostic Overview.


Diagnostic Test


1. CAN SUPPLIED MESSAGES

NOTE: To help in the service of the Adaptive Cruise Control (ACC) System, it is recommended speaking to the customer to find out what type of environment they were driving in when the cruise concern took place. Heavy rain, snow, ice and fog can cause the ACC system to become unavailable. This should be considered normal operation and no repair is necessary.


NOTE: Repair all ABS and/or ESP DTC(S). There was a conflicting message between the ESP system the ACC module. The DTC can be clear, no repair is necessary.
