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 ignition switch is in the RUN position and the REVERSE (R) gear is selected. The parking aid module (PAM) receives reverse gear input from the instrument cluster (IC) through the medium speed controller area network (MS-CAN). Voltage is supplied to the parking aid sensors from the PAM on circuit LMP07 (BU/WH). The PAM supplies ground to the parking aid sensors on circuit RMP07 (GN/WH). The parking aid module (PAM) receives a signal from the parking aid sensors on circuits VMP14 (WH/OG), VMP15 (YE/GN), VMP16 (YE/GY) and VMP17 (YE/OG). The system can be disabled through the message center which is part of the IC.

This pinpoint test is intended to diagnose the following:
- Rear bumper cover
- Parking aid sensors alignment
- PAM
