Diagnostic Test
NOTE:
- To help in the service of the 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.
- Repair all ABS and ESP DTCs. There was a conflicting message between the ESP system the ACC module. The DTC can be cleared. No repair is necessary.
