Diagnostic Fault Information
Circuit/System Description
The parking assist can be activated/deactivated by pressing the parking assist switch. By engaging the reverse gear the parking assist can also be activated. By subsequently pressing the parking assist switch the parking assist can be disabled again.
The indicator in the parking assist switch shows the status of the parking assist. If the lamp is ON, the parking assist is activated.
Conditions for Running the DTC
* Ignition ON
* The parking assist is activated. The activation takes place by putting in the reverse gear or by pressing the parking assist switch.
Conditions for Setting the DTC
B0967 02
The parking assist control module has detected a short to ground.
B0968 01
The parking assist control module has detected a short to battery.
B0968 06
The parking assist control module has detected a short to ground or open.
Action Taken When the DTC Sets
* The parking assist is disabled.
* The driver information center displays SERVICE PARK ASSIST.
Conditions for Clearing the DTC
The condition for setting the DTC is no longer present.

Circuit/System Verification
1. Verify that DTC B0967 02 is not present.
• If DTC is present, refer to Parking Assist Switch Malfunction.
2. Verify that B0968 01 or B0968 06 is not present.
• If DTC is present, refer to Parking Assist Switch Indicator Malfunction.
3. Activate and deactivate the parking assist switch and verify the scan tool Park Assist Switch parameter changes between Active and Inactive.
Circuit/System Testing
Parking Assist Switch Malfunction
1. Ignition OFF, disconnect the X3 harness connector at the K41R Rear Parking Assist Control Module.
2. Test for infinite resistance between the input signal circuit terminal 8 X3 at the K41R Rear Parking Assist Control Module harness connector and ground.
• If less than the specified value, test input signal circuit for a short to ground. If the circuit tests normal, replace the S48D Multi-Function Switch 2 - Instrument Panel.
3. If all circuits test normal, replace the K41R Rear Parking Assist Control Module.
Parking Assist Switch Indicator Malfunction
1. Ignition OFF, disconnect the X3 harness connector at the K41R Rear Parking Assist Control Module and the X1 harness connector at the S48D Multi-Function Switch 2 - Instrument Panel.
2. Ignition ON, test for greater than 11 V between the ignition circuit terminal 3 X1 and ground.
• If less than the specified value, test the ignition circuit for a short to ground or an open/high resistance.
3. Test for less than 0.3 V between the control circuit terminal 3 X3 at the K41R Rear Parking Assist Control Module harness connector and ground.
• If greater than the specified value, test the control circuit for a short to voltage.
4. Ignition OFF, test for infinite resistance between the control circuit terminal 3 X3 at the K41R Rear Parking Assist Control Module harness connector and ground.
• If less than the specified value, test control circuit for a short to ground.
5. Test for less than 5 ohms between the S48D MultiFunction Switch 2 - Instrument Panel control circuit terminal 6 X1 and the control circuit terminal 3 X3 at the K41R Rear Parking Assist Control Module harness connector
• If greater than the specified value, test the control circuit for an open/high resistance.
6. If all circuits test normal, connect the X3 harness connector to the K41R Rear Parking Assist Control Module, replace the S48D MultiFunction Switch 2 - Instrument Panel and verify the DTC does not reset.
• If the DTC resets, replace the K41R Rear Parking Assist Control Module.
