DTC Descriptor
DTC B0967 02
- Parking Aid Switch Circuit Short to Ground




Diagnostic Fault Information






Circuit/System Description

The parking assist system can be disabled by pressing the parking assist disable switch. When pressed, the parking assist disable signal circuit is pulled to ground. When parking assist is disabled, the object alarm module also ground the parking assist disable indicator control circuit, illuminating the indicator.


Conditions for Running the DTC

* DTC B1325 is not set
* Ignition voltage is between 9-16 volts.



Conditions for Setting the DTC

The object alarm module has detected that the parking assist disable switch signal circuit is shorted to ground.


Action Taken When the DTC Sets

* The parking assist system defaults to the enabled state.
* The parking assist disable indicator is not illuminated.



Conditions for Clearing

* The DTC will transition to history when the fault is no longer present.
* A history DTC will clear after 100 malfunction-free ignition cycles.

Circuit/System Verification

Ignition ON, observe the scan tool Park Assist Switch parameter while cycling the parking assist disable switch. They should change between Active and Inactive.


Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the I/P multifunction switch assembly.
2. Test for less than 1.0 ohm between the ground circuit terminal 3 and ground.

• If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that the scan tool Park Assist Switch parameter is Inactive.

• If not the specified value, test the signal circuit terminal 2 for a short to ground. If the circuit tests normal, replace the object alarm module.

4. Ignition OFF, connect a 3A fused jumper wire between signal circuit terminal 2 and ground.
5. Ignition ON, verify that the scan tool Park Assist Switch parameter is Active.

• If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the object alarm module.

6. If all circuits test normal, test or replace the I/P accessory switch assembly.
