DIAGNOSTIC PROCEDURE - FLIP-UP GLASS RELEASE INOPERATIVE
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | With the DRBIII® in Inputs/Outputs, read the FLIP-UP GLASS REL SW state. Observe the DRBIII® and move the tailgate handle from open to close positions. Does the DRBIII® display OPEN then CLOSED as the handle is moved? Yes --> Go To 2 No --> Go To 6 |
All |
| 2 | Disconnect the Flip-Up Glass Release Motor connector. Connect a 12-volt test light between the Flip-Up Glass Release Motor Driver circuit and the ground circuit in the motor connector. With the DRBIII®, actuate the RELEASE FLIP-UP GLASS. Does the test light illuminate brightly when the motor is actuated? Yes --> Replace the Flip-Up Glass Release Motor. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 3 |
All |
| 3 | Disconnect the Flip-Up Glass Release Motor connector. Using a 12-volt test light connected to 12-volts, check the Ground circuit in the motor connector. Does the test light illuminate brightly? 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 Flip-Up Glass Release Motor connector. Connect a jumper wire between Flip-Up Glass Release Motor Driver circuit and ground in the motor connector. Disconnect the Body Control Module C1 connector. Measure the resistance between ground and the Flip-Up Glass Release Motor Driver circuit. Is the resistance below 5.0 ohms? Yes --> Go To 5 No --> Repair the Flip-Up Glass Release Motor Driver circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 5 | If there are no possible causes remaining, view repair. Repair Replace the Body Control Module. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 6 | Remove the tailgate trim panel. Disconnect the Flip-Up Glass Release Switch. connector. Connect a jumper wire between Flip-Up Glass Release Switch. circuit and Tailgate Switch Ground circuit in the switch connector. With the DRBIII® in Inputs/Outputs, read the Flip-Up Glass Rel Sw state. Does the DRBIII® display CLOSED? Yes --> Replace the Flip-Up Glass Release Switch. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 7 |
All |
| 7 | Remove the tailgate trim panel. Disconnect the Flip-Up Glass Release Switch. connector. Using a 12-volt test light connected to 12-volts, check the Tailgate Switch Ground circuit. Does the test light illuminate brightly? Yes --> Go To 8 No --> Repair the Ground circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 8 | Remove the tailgate trim panel. Disconnect the Flip-Up Glass Release Switch. connector. Connect a jumper wire between Flip-Up Glass Release Switch. Sense circuit and ground. Disconnect the Body Control Module C1 connector. Measure the resistance between ground and the Flip-Up Glass Release Switch Sense circuit. Is the resistance below 5.0 ohms? Yes --> Go To 9 No --> Repair the Flip-Up Glass Release Switch Sense circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 9 | If there are no possible causes remaining, view repair. Repair Replace the Body Control Module. Perform BODY VERIFICATION TEST - VER 1 . |
