Normal Operation

When the parking aid sensors detect obstructions in the path behind the vehicle, a variable rate warning tone is generated from the parking aid speaker. The parking aid speaker increases the warning tone rate as the vehicle gets closer to an obstacle. A fault condition occurs when the Parking Aid Module (PAM) detects an open, short to ground or short to voltage on the parking aid speaker circuits.

- DTC B1B52:12 (Rear Sounder-Park Aid: Circuit Short To Battery) - sets when the sounder circuit is shorted to voltage.

- DTC B1B52:14 (Rear Sounder-Park Aid: Circuit Short To Ground Or Open) - sets when the sounder circuit is open or shorted to ground.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- PAM (Parking Aid Module)

- Parking aid speaker
