|
Yes |
Go to step 13. |
| No |
Repair the circuit. Test the system for normal operation. |
| 8 |
CHECK CIRCUITS V/W AND LG/R FOR AN OPEN
- Disconnect: Instrument Cluster 0922-101.
- Measure the resistance between the instrument cluster 0922-101 pin 20, circuit V/W, harness side and the parking brake switch 0918-105 pin 1, circuit R/Y, harness side.
- Is the resistance less than 5 ohms?
|
Yes |
Go to step 11. |
| No |
Go to step 9. |
| 9 |
CHECK CIRCUIT LG/R FOR AN OPEN
- Disconnect: Smart Junction Box (SJB) J-2280C.
- Measure the resistance between the parking brake switch 0918-105 pin 1, circuit R/Y, harness side and the SJB J-2280c pin 17, circuit R/Y, harness side.
- Is the resistance less than 5 ohms?
|
Yes |
Go to step 10. |
| No |
Repair the circuit. Test the system for normal operation. |
| 10 |
CHECK CIRCUIT V/W FOR AN OPEN
- Measure the resistance between the instrument cluster 0922-101 pin 20, circuit V/W, harness side and the SJB J-2280c pin 18, circuit V/W, harness side.
- Is the resistance less than 5 ohms?
|
Yes |
Go to step 12. |
| No |
Repair the circuit. Test the system for normal operation. |
| 11 |
CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect all instrument cluster connectors.
- Check for:
- corrosion
- pushed-out pins
- Connect all instrument cluster connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
|
Yes |
Install a new instrument cluster. See INSTRUMENT CLUSTER REMOVAL/INSTALLATION
. Clear the DTCs. REPEAT the instrument cluster self-test. |
| No |
