Diagnosis And Testing - Blind Spot Display

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 the Blind Spot Monitor (BSM) displays and the Driver Door Module (DDM) or Passenger Door Module (PDM) 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 BSM displays or the electronic controls and communication between other modules and devices that provide some features of the BSM displays. The most reliable, efficient and accurate means to diagnose the BSM displays or the electronic controls and communication related to BSM display operation requires the use of a diagnostic scan tool.
