Test A: The Parking Aid Is Inoperative/Does Not Operate Correctly

PINPOINT TEST A: THE PARKING AID IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
The parking aid system is enabled when the vehicle ignition is in RUN and REVERSE (R) is selected. The parking aid module supplies voltage to the parking aid sensors on circuit LMP07 (BU/WH). The parking aid module supplies ground to the parking aid sensors on circuit RMP07 (GN/WH). The parking aid module receives a signal from the parking aid sensors on circuits VMP17 (YE/OG), VMP16 (YE/GY), VMP14 (WH/OG) and VMP15 (YE/GN). The system can be disabled through the disable switch. A 750 Hz variable warning tone is generated from a parking aid speaker which increases the warning tone rate as the vehicle gets closer to an obstacle.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Rear bumper cover
- Parking aid sensor alignment
- Parking aid disable switch
- Parking aid module
