Fixing the Malfunctioning Rear Liftgate on a 2020-Present Toyota Highlander (XU70)
Tools Required
  • OBD-II scanner
  • Multimeter
  • Screwdrivers (Phillips and flathead)
  • T20 Torx bit
  • Torque wrench
  • Socket set
  • Trim removal tools
  • Lubricant (silicone spray or white lithium grease)
Repair Instructions

Step 1: Battery Check

  • Replace the key fob battery if it is weak. Ensure it is correctly installed.

Step 2: Inspect the Liftgate Switch

  • Access the switch: Use a trim removal tool to gently pry off the cover around the liftgate switch.
  • Test the switch: Disconnect the connector from the switch and test for continuity using a multimeter. If defective, replace the switch.

Step 3: Check for Obstructions

  • Open the liftgate manually if possible and inspect the hinges, struts, and tracks. Clean any debris or obstructions.

Step 4: Visual Inspection of Components

  • Inspect the wiring harness for any frayed wires or loose connections. Repair or replace as necessary.
  • Check for any damaged components such as the liftgate latch or struts.

Step 5: Scan for Trouble Codes

  • Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
  • Check for any stored codes related to the liftgate. Document any codes and refer to the service manual for further diagnosis based on the codes.

Step 6: Test the Liftgate Motor

  • Access the liftgate motor: Remove the interior trim panel using a T20 Torx bit and socket set.
  • Test voltage: With the liftgate switch activated, use a multimeter to check if the motor is receiving voltage. If there is no voltage, trace the wiring back to the switch or control module.
  • Replace the motor: If the motor is faulty, disconnect it, remove the mounting screws, and replace it with a new unit. Reconnect the wiring.

Step 7: Lubricate Moving Parts

  • Apply lubricant to the liftgate hinges and tracks. This can help improve movement and prevent future issues.

Step 8: Reassemble and Test

  • Reinstall the interior trim panel by aligning it correctly and securing it with screws.
  • Test the liftgate operation using the key fob, the interior switch, and the liftgate button. Ensure it opens and closes smoothly.
Conclusion

If the problem persists after following these steps, it may be necessary to consult a professional technician or visit a Toyota dealer for further diagnosis. Advanced issues may involve the vehicle’s Body Control Module (BCM) or programming, which requires specialized tools and knowledge.
