Diagnostic Procedure
DIAGNOSTIC INFORMATION AND PROCEDURES CHART (CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN)
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition on. Open the driver door. With the DRB, read the "DR DOOR AJAR SW" state. Does the DRB display "DR DOOR AJAR SW: CLOSED"? Yes --> Go To 2 No --> Go To 6 |
All |
| 2 | Turn the ignition off. Disconnect the Ignition Switch harness connector.
NOTE:
Ensure the key is in the Ignition Switch Lock Cylinder. Measure the resistance of the Key-in Ignition Switch with the key in. Is the resistance below 20 ohms? Yes --> Go To 3 No --> Check the Ignition Lock Cylinder for damage. If OK, replace the Ignition Switch. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 3 | Turn the ignition off. Disconnect the Ignition Switch harness connector. Measure the resistance of the ground circuit in the ignition switch harness connector. Is the resistance below 5.0 ohms? Yes --> Go To 4 No --> Repair the ground circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 4 | Turn the ignition off. Disconnect the Ignition Switch harness connector. Remove the Instrument Cluster from the I/P. Measure the resistance of the Key-in Ignition Switch Sense circuit between the ignition switch harness connector and the Instrument Cluster C2 connector. Is the resistance below 5.0 ohms? Yes --> Go To 5 No --> Repair the key-in ignition switch sense circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 5 | If there are no possible causes remaining, view repair. Repair Replace the Instrument Cluster in accordance with the Service Information.. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 6 | Gain access to the Fuse Block Fuse #4 and inspect. Was the fuse missing or open? Yes --> Replace Fuse. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 7 |
All |
| 7 | Using a 12-volt Test Light connected to 12-volts, test the Ground circuit at fuse #4 for continuity. Does the light illuminate? Yes --> Go To 8 No --> Repair the Ground circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 8 | Reinstall fuse if removed in previous test. Disconnect the Driver Door Ajar Switch connector. With the DRBIII® in Inputs/Outputs, read the DRV DR AJAR SW state. Connect a jumper wire between Sense circuit and the Output circuit. Does the DRBIII® display DRV DR AJAR SW: CLOSED? Yes --> Replace the Driver Door Ajar Switch. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 9 |
All |
| 9 | Disconnect the Driver Door Ajar Switch connector. Measure the resistance of the Door Ajar Output from the ajar switch to the fuse. Is the resistance below 5.0 ohms? Yes --> Go To 10 No --> Repair the Door Ajar Switch Output circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 10 | Remove the Instrument Cluster from the I/P. Disconnect the Driver Door Ajar Switch connector. Measure the resistance of the Driver Door Ajar Switch Sense circuit from the Driver Door Ajar switch to the Instrument Cluster C2 connector. Is the resistance below 5.0 ohms? Yes --> Go To 11 No --> Repair the Driver Door Ajar Switch Sense circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 11 | If there are no possible causes remaining, view repair. Repair Replace the Instrument Cluster in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
