Diagnostic Aids
- Whenever the liftgate control module loses power or is disconnected, the ignition must be cycled OFF then ON in order to reactivate the liftgate control module.
- Check the calibration software installed on the liftgate control module prior to performing extensive diagnostics, vehicles with the handsfree liftgate control option (TC2) require specific calibration software. Incorrect calibration software may cause the power liftgate system to become inoperative without setting any DTCs
- Remote power liftgate functions may be disabled if a second keyless entry transmitter is inside the vehicle
