Circuit/System Verification
1. Verify that DTC B0967 02 is not present.
瀚慖f DTC is present, refer to Parking Assist Switch Malfunction.
2. Verify that B0968 01 or B0968 06 is not present.
瀚慖f 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 S48E multi-function switch module - center console.
2. Test for less than 10 ohm between the ground circuit terminal 2 and ground.
瀚慖f greater than the specified value, test the ground circuit for an open/high resistance.
3. Connect the harness connector at the S48E multi-function switch module - center console.
4. Disconnect the X1 harness connector at the K41 parking assist control module.
5. Ignition ON, test for less than 0.3 V between the signal circuit terminal 8 X1 and ground.
瀚慖f greater than the specified value, test the signal circuit for a short to voltage.
6. Ignition ON, verify that a test lamp does not illuminate between the B+ circuit terminal 1 X1 and signal circuit terminal 8 X1.
瀚慖f the test lamp illuminates, test signal circuit for a short to ground. If the circuit tests normal, replace the S48E multi-function switch
module - center 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.
瀚慖f the test lamp does not illuminate, test the signal circuit for an open/high resistance. If all circuits test normal, replace the S48E
multi-function switch module - center console.
8. If all circuits test normal, replace the K41 parking assist control module.
Parking Assist Switch Indicator Circuit Malfunction
1. Ignition OFF, disconnect the harness connector at the S48E multi-function switch module - center console.
2. Ignition ON, test for B+ between the ignition circuit terminal 3 and ground.
瀚慖f 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.
瀚慖f less than the specified value, test the signal circuit for an open/high resistance. If all circuits test normal, replace the K41 parking assist
