| 3 | Disconnect the Body Control Module C4 connector. Disconnect the Power Top Switch connector. Measure the voltage of the Convertible Top Switch Mux circuit to ground. Is there any voltage present? Yes --> Repair the Convertible Top Switch Mux wire for a short to battery. Perform BODY VERIFICATION TEST - VER 1 . No --> Replace Convertible Top Switch. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 4 | Disconnect the Body Control Module C4 connector. Measure the resistance between ground and the Convertible Top Switch Mux circuit. Is the resistance between 4500.0 and 4900,0 ohms? Yes --> Replace the Body Control Module. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 5 |
All |
| 5 | Disconnect the Power Top Switch connector. Using a 12-volt test light connected to 12-volts, check the Ground circuit in the Power Top Switch connector. Does the test light illuminate brightly? Yes --> Go To 6 No --> Repair the Ground circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 6 | Disconnect the Body Control Module C4 connector. Disconnect the Power Top Switch connector. Measure the resistance of the Convertible Top Switch Mux circuit from the BCM C4 connector to the Power Top Switch connector. Is the resistance below 5.0 ohms? Yes --> Go To 7 No --> Repair the Convertible Top Switch Mux wire for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 7 | If there are no possible causes remaining, view repair. Repair Replace the Convertible Top Switch. Perform BODY VERIFICATION TEST - VER 1 . |
