Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnosis And Testing - Blind Spot Display
The hardwired 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, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, Refer to WIRE SPLICING and connector repair procedures. Refer to REMOVAL and Refer to INSTALLATION .
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.
