Parking Aid

Pinpoint Test G: DTC B1B58:11

Refer to Wiring Diagram Set 131, Parking Aid for schematic and connector information. Diagrams By Number

Normal Operation

For rear parking aid system, the Parking Aid Module (PAM) supplies a reference voltage and signal return to the parking aid sensors. A fault condition occurs when the PAM detects a short to ground or short to signal return circuit on the parking aid sensor voltage supply circuit for the front or the rear parking aid sensors.

- DTC B1B58:11 (Rear Sensors Power Circuit: Circuit Short To Ground) - sets when the sensor voltage supply circuit is shorted to ground or to the signal return circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Parking aid sensor(s)
- Parking aid bumper harness
- PAM
