2. Ignition OFF for 30 seconds, test for less than 20 Ohms between the low reference circuit terminal 2 and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the object

alarm module.

3. Ignition ON, transmission in REVERSE, test for 8.0-9.0 V between the voltage reference circuit terminal 1 and ground.

瀚慖f greater than the specified range, test the voltage reference circuit for a short to voltage. If the circuit tests normal, replace the object

alarm module.

瀚慖f less than the specified range, test the voltage reference circuit for a short to ground or an open/high resistance. If the circuit tests

normal, replace the object alarm module.

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 the parking assist system is disabled, the object alarm module will 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 is disabled.

* The parking assist disable indicator is not illuminated.

* The object alarm module sends a serial data message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message in

the driver information center (DIC).
