Diagnosis And Testing - Acc System

WARNING: This page is about a different car, the 2014 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

The hard wired circuits to the adaptive speed control sensor (also known as the Adaptive Cruise Control/ACC sensor or module, or the radar sensor or module) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the ACC sensor or the electronic controls and communication between modules and other devices that provide some features of the adaptive speed control and Forward Collision Warning (FCW) systems. The most reliable, efficient, and accurate means to diagnose the ACC sensor or the electronic controls and communication related to adaptive speed control or FCW system operation requires the use of a diagnostic scan tool.
