DIAGNOSTIC PROCEDURE - ALL DOORS FAILING TO LOCK AND UNLOCK FROM ONE SWITCH
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Operate the door locks from the door lock switches and the door cylinder lock switches (if equipped). Is the problem with a Door Cylinder Lock Switch (VTSS)? Yes --> Go To 2 No --> Go To 7 |
All |
| 2 | Disconnect the inoperative Door Cylinder Lock Switch connector. Measure the voltage between the Fused B(+) circuit and ground. Is the voltage above 10.0 volts? Yes --> Go To 3 No --> Repair the Fused B(+) circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 3 | Disconnect the inoperative Door Cylinder Lock Switch connector. Disconnect the BCM C4 connector. Measure the resistance between ground and the Cylinder Lock Switch Mux circuit. Is the resistance below 1000.0 ohms? Yes --> Repair the Door Cylinder Lock Switch Mux circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 4 |
All |
| 4 | Disconnect the inoperative Door Cylinder Lock Switch connector. Disconnect the BCM C4 connector. Measure the resistance of the Cylinder Lock Switch Mux circuit between the Switch connector and the BCM C4 connector. Is the resistance below 5.0 ohms? Yes --> Go To 5 No --> Repair the Door Cylinder Lock Switch Mux circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 5 | Disconnect the inoperative Door Cylinder Lock Switch connector. Connect a jumper wire between the appropriate Cylinder Lock Switch Mux circuit and Fused B(+). With the DRBIII® in Sensors, read the appropriate Door Arm/Disarm Switch voltage. Is the voltage above 9.0 volts? Yes --> Replace the appropriate Door Cylinder Lock Switch. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 6 |
All |
| 6 | If there are no possible causes remaining, view repair. Repair Replace the Body Control Module in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 7 | Disconnect the inoperative Door Lock Switch connector. Measure the voltage between the Fused B(+) circuit and ground. Is the voltage above 10.0 volts? Yes --> Go To 8 No --> Repair the Fused B(+) circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 8 | Disconnect the inoperative Door Lock Switch connector. Disconnect the BCM C4 connector. Measure the resistance between ground and the Door Switch Mux circuit. Is the resistance below 1000.0 ohms? Yes --> Repair the Door Switch Mux circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 9 |
All |
| 9 | Disconnect the inoperative Door Lock Switch connector. Disconnect the Body Control Module C4 connector. Measure the resistance of the Door Switch Mux circuit between the Door Lock Switch connector and the BCM C4 connector. Is the resistance below 5.0 ohms? Yes --> Go To 10 No --> Repair the Door Switch Mux circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 10 | Disconnect the inoperative Door Lock Switch connector. Connect a jumper wire between the Door Switch Mux circuit and Fused B(+). With the DRBIII®, read the Door Lock Sw Volts status. Is the voltage above 9.0 volts? Yes --> Replace the Power Door Lock Switch. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 11 |
All |
| 11 | If there are no possible causes remaining, view repair. Repair Replace the Body Control Module. Perform BODY VERIFICATION TEST - VER 1 . |
