| Circuit/System Verification |
| 1. |
Verify that DTC B0967 02 is not present.
|
|
| 2. |
If DTC is present, refer to Parking Assist Switch Malfunction.
|
|
| 3. |
Verify that B0968 01 or B0968 06 is not present.
|
|
| 4. |
If DTC is present, refer to Parking Assist Switch Indicator Malfunction.
|
|
| 5. |
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 S48D multi-function switch module - dashboard.
|
|
| 2. |
Test for less than 10 Ω between the ground circuit terminal 2 and ground.
|
|
| 3. |
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
| 4. |
Connect the harness connector at the S48D multi-function switch module - dashboard.
|
|
| 5. |
Disconnect the cable harness switch X1 at the front and rear control modules for Saab Park Assistance, K41.
|
|
| 6. |
Ignition ON, test for less than 0.3 V between the signal circuit terminal 8 X1 and ground.
|
|
| 7. |
If greater than the specified value, test the signal circuit for a short to voltage.
|
|
| 8. |
Ignition ON, verify that a test lamp does not illuminate between the B+ circuit terminal 1 X1 and signal circuit terminal 8 X1.
|
|
| 9. |
If the test lamp illuminates, test signal circuit for a short to ground. If the circuit tests normal, replace the S48D multi-function switch module - dashboard.
|
|
| 10. |
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.
|
|
| 11. |
If the test lamp does not illuminate, test the signal circuit for an open/high resistance. If all circuits test normal, replace the S48D multi-function switch module - center console.
|
|
| 12. |
If all circuits test normal, replace the Front and Rear Parking Assist Control Modules, K41.
|
|
Parking Assist Switch Indicator Circuit Malfunction
| 1. |
Ignition OFF, disconnect the harness connector at the S48D multi-function switch module - dashboard.
|
|
| 2. |
Ignition ON, test for B+ between the ignition circuit terminal 3 and ground.
|
|
| 3. |
If less than the specified value, test the ignition circuit for a short to ground or an open/high resistance.
|
|
| 4. |
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.
|
|
| 5. |
If less than the specified value, test the signal circuit for an open/high resistance. If all circuits test normal, replace the K41 parking assist control module.
|
|
| 6. |
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.
|
|
| 7. |
If greater than the specified value, test the signal circuit for a short to ground. If all circuits test normal, replace the K41 parking assist control module.
|
|
| 8. |
If all circuits test normal, replace the S48D multi-function switch module - dashboard.
