| Diagnosis and Testing Refer to Wiring Diagrams Section 413-13, for schematic and connector information. Worldwide Diagnostic System (WDS) Principles of Operation NOTE:The liftgate or rear doors must be closed for correct operation of the parking aid system. The parking aid system detects objects behind the vehicle when the vehicle reverse gear select input to the control module is enabled. The parking aid module does this by calculating the distance to an object by the use of four ultrasonic sensors mounted in the rear bumper. The sensors can detect objects approximately 1.8 meters to the rear of the vehicle, 50 centimeters to the rear-side of the vehicle, and 16 centimeters above the ground. An intermittent warning tone is generated from a speaker located behind the instrument panel. The interval between the tones decreases as the vehicle gets closer to an obstacle. When an object is detected within 25 centimeters of the sensors, the warning tone becomes continuous. The parking aid system will be disabled if a fault is detected in one of the four sensors, the parking aid speaker or the parking aid module. Inspection and Verification - Verify the customer concern.
- Visually inspect for obvious signs of electrical damage.
