Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdriver, socket set), and cleaning supplies.
Ensure the vehicle is parked on a flat surface and is in 'Park'.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean the Camera

Locate the rearview camera, typically mounted near the tailgate handle.
Carefully remove the camera housing using a screwdriver.
Inspect for any physical damage or dirt obstructing the lens.
Clean the lens with a microfiber cloth and appropriate cleaner.
Reinstall the camera housing securely.

3. Check Wiring and Connections

Reconnect the battery temporarily and switch on the ignition.
Verify the wiring harness for any signs of wear or damage.
Use a multimeter to test for voltage at the camera connector (should be around 12V).
If no voltage is present, trace the wiring back to the vehicle's main harness and check for continuity.

4. Replace the Camera (if necessary)

If the camera is faulty, procure a replacement camera compatible with your Toyota Highlander.
Disconnect the wiring harness from the old camera.
Remove the old camera from its mounting position.
Install the new camera by reversing the removal process.
Reconnect the wiring harness.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and shift into reverse to test the functionality of the rearview camera.
Ensure the display shows the rear view clearly and without distortion.
