- If the hands - free liftgate sensor lamp does not turn ON and OFF
- Verify the vehicle locks and unlock with the RKE Transmitter.
- If the vehicle does not lock/unlock
Refer to: Keyless Entry System Malfunction
- Go to next step: If the vehicle does lock/unlock
- If the vehicle does not lock/unlock
- Verify one of the scan tool data parameters listed below are Active with the RKE transmitter inside the vehicle.
- Key Fob 1 in Vehicle
- Key Fob 2 in Vehicle
- If one of the parameters are not Active
Approach lighting will not illuminate, acquire RKE transmitter 1 or 2 and retest.
- Go to next step: If one of the parameters are Active
