Some customers may comment that the power liftgate opens about a third of the way and then reverses to the closed position. Other customers may comment that when the power liftgate is open, the liftgate starts to close about a third of the way and then reopens. The technician may find diagnostic trouble codes (DTCs) B153E-Liftgate Position Sensor Signal Circuit and/or B153F-Liftgate Object Sensor Signal Circuit set.
The cause may be a sharp sheet metal edge inside the inner roof panel chafing the liftgate wiring harness.
Inspect the liftgate wiring harness and repair as necessary using the steps below.
Important: Do not fold or crease the headliner panel.
Tip
Use a shop towel when disconnecting the rear washer hose to help absorb any washer fluid that may leak.
