DTC Descriptor

DTC B0967 02
- Parking Aid Switch Circuit

Circuit/System Description

The object alarm detection system senses how close the vehicle is to an object. The distance is determined by the 4 ultrasonic sensors located in the rear bumper. The object detection system will notify the driver when backing up or moving forward while parking at speeds less than 8 km/h (5 mph). The object detection system will use rear display indicators and the radio speakers for notification. The system can be disabled by pressing the ON/OFF button. The ON/OFF indicator will be ON when the system is OFF. The driver information center (DIC) will also display PARK ASSIST OFF.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

The object alarm module has detected that the switch circuit is determined to be shorted to ground and must exist for 300 milliseconds.

Action Taken When the DTC Sets

* The object alarm module commands ON the telltale assembly information center red indicator and disables the object detection system.
* The object alarm module will send a serial data message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message in the driver information center (DIC) and a chime will sound from the radio speakers.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the I/P multifunction assembly switch.
2. Ignition ON, verify the scan tool Park Assist Switch parameter is Inactive.

• If not Inactive, test the rear park disable signal circuit for a short to ground. If the circuit tests normal, replace the object alarm module

3. Ignition OFF, test for greater than 1.0 ohm of resistance between the rear park assist disable signal of the I/P multifunction assembly switch and ground.

• If less than 1.0 ohm, test the rear park assist disable signal circuit at the I/P multifunction assembly switch for a short to ground.
• If all circuits test normal, replace the I/P multifunction assembly switch.
