DTC B0967 or B0968

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.

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.

The condition for setting the DTC is no longer present.

Control Module References for scan tool information

1. Verify that DTC B0967 02 is not present.

⇒	If DTC is present, refer to Parking Assist Switch Circuit Malfunction.

2. Verify that B0968 01 or B0968 06 is not present.

⇒	If DTC is present, refer to Parking Assist Switch Indicator Circuit Malfunction.

3. Activate and deactivate the parking assist switch and verify the scan tool Park Assist Switch parameter changes between Active and Inactive.

Parking Assist Switch Circuit Malfunction

1. Vehicle OFF, disconnect the harness connector at the S48B Multifunction Switch - Overhead Console.
2. Test for less than 10 Ω between the ground circuit terminal 2 and ground.

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

3. Connect the harness connector at the S48B Multifunction Switch - Overhead Console.
4. Disconnect the X1 harness connector at the K41 Front and Rear Parking Assist Control Module.
5. Vehicle in Service Mode, test for less than 0.3 V between the signal circuit terminal 8 X1 and ground.

⇒	If greater than the specified value, test the signal circuit for a short to voltage.

6. Vehicle in Service Mode, verify that a test lamp does not illuminate between the B+ circuit terminal 1 X1 and signal circuit terminal 8 X1.

⇒	If the test lamp illuminates, test signal circuit for a short to ground. If the circuit tests normal, replace the S48B Multifunction Switch - Overhead Console.

7. Verify that the test lamp illuminates between the B+ circuit terminal 1 X1 and signal circuit terminal 8 X1 while pressing the parking assist switch.

⇒	If the test lamp does not illuminate, test the signal circuit for an open/high resistance. If all circuits test normal, replace the S48B Multifunction Switch - Overhead Console.

8. If all circuits test normal, replace the K41 Front and Rear Parking Assist Control Module.

Parking Assist Switch Indicator Circuit Malfunction

1. Vehicle OFF, disconnect the harness connector at the S48B Multifunction Switch - Overhead Console.
2. Vehicle in Service Mode, test for B+ between the ignition circuit terminal 3 and ground.

⇒	If less than the specified value, test the ignition circuit for a short to ground or an open/high resistance.

3. Command the Park Assist Switch LED output control ON with the scan tool. Test for B+ between the ignition circuit terminal 3 and the signal circuit terminal 6.

⇒	If less than the specified value, test the signal circuit for an open/high resistance. If all circuits test normal, replace the K41 Front and Rear Parking Assist Control Module.

4. Command the Park Assist Switch LED output control OFF with the scan tool. Test for less than 0.3 V between the ignition circuit terminal 3 and the signal circuit terminal 6.

⇒	If greater than the specified value, test the signal circuit for a short to ground. If all circuits test normal, replace the K41 Front and Rear Parking Assist Control Module.

5. If all circuits test normal, replace the S48B Multifunction Switch - Overhead Console.

Perform the Diagnostic Repair Verification after completing the repair.
