Diagnosis And Testing - Lane Departure Warning

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

The hard wired circuits between components related to the Lane Departure Warning (LDW) system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, 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 LDW system or the electronic controls and communication between modules and other devices that provide some features of the LDW system. The most reliable, efficient and accurate means to diagnose the LDW system or the electronic controls and communication related to LDW system operation requires the use of a diagnostic scan tool.
