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 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 Circuit Malfunction
1. Ignition OFF, disconnect the harness connector at the S107 parking assist disable switch.
2. Test for less than 10 ohms between the S107 parking assist disable switch ground circuit terminal 2 and ground.
• If greater than the specified value, test the ground circuit for an open/high resistance.
3. Ignition ON, test for 11-13 V between the reference circuit terminal 5 at the S107 parking assist disable switch harness connector and ground.
• If less than the specified range, test the reference circuit for a short to ground or an open/high resistance. If circuit tests normal, replace the K41 front and rear parking assist control module.
4. If all circuits test normal, replace the S107 parking assist disable switch.
Parking Assist Switch Indicator Circuit Malfunction
1. Ignition OFF, disconnect the harness connector at the S107 parking assist disable switch.
2. Ignition ON, transmission in REVERSE, test for 0.05-0.15 V between the signal terminal 6 at the S107 parking assist disable switch harness connector and ground.
• If less than the specified range, test signal circuit for a short to ground or an open/high resistance. If circuit tests normal, replace K41 front and rear parking assist control module.
• If greater than the specified range, test signal circuit for short to voltage. If circuit tests normal, replace K41 front and rear parking assist control module.
3. If all circuits test normal, replace the S107 parking assist disable switch.
