Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is in park and the ignition is off before starting work.

2. Clean the Camera Lens

Sub-steps:
1. Locate the rearview camera, typically mounted above the license plate.
2. Use a soft cloth with a gentle cleaner to wipe the lens clean of any dirt or moisture.
3. Ensure the lens is dry and clear before proceeding.

3. Inspect and Secure Connections

Sub-steps:
1. Remove the rear trim panel if necessary to access the camera harness.
2. Disconnect the camera connector and inspect for corrosion or damage.
3. Reconnect the harness securely, ensuring a tight fit.
4. Check the connection at the multimedia unit for any loose or damaged wires.

4. Test Voltage at the Camera

Sub-steps:
1. Reconnect the camera but leave the trim panel off for access.
2. Turn on the vehicle and set it in reverse.
3. Use a multimeter to check for voltage at the camera harness connector; it should receive around 12V.
4. If voltage is absent, trace wiring back to the multimedia unit for faults.

5. Replace Camera or Fuse

Sub-steps:
1. If the camera is faulty, order a replacement camera compatible with the 2020-Present Highlander.
2. If a fuse is blown, replace it with an equivalent rated fuse (check the owner’s manual for specifications).
