Diagnosis And Testing
The hardwired circuits between the Ultrasonic and Anti-tilt Module (UAM) and the Body Control Module (BCM) 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 UAM or the electronic controls and communication between other modules and devices that provide some features of the Vehicle Theft Alarm (VTA) system. The most reliable, efficient and accurate means to diagnose the UAM or the electronic controls and communication related to VTA system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
