Issue: Rearview Camera Not Working in 2020 Toyota Highlander

Tools Required

OBD-II scanner
Multimeter
Screwdriver set
Trim removal tool
Cleaning materials (microfiber cloth, water, mild soap)
Electrical contact cleaner (if needed)

Repair Instructions

Step 1: Clean the Camera Lens

Use a microfiber cloth and mild soap solution to clean the rearview camera lens. Ensure there is no dirt or debris obstructing the camera view.
Rinse with clean water and dry thoroughly.

Step 2: Check the Reverse Lights

Shift the vehicle into reverse and ensure the reverse lights turn on.
If the reverse lights do not illuminate, check the reverse light fuse in the fuse box (refer to the owner's manual for the specific fuse location).

Step 3: Inspect Wiring and Connections

Open the rear hatch and locate the wiring harness that connects to the rearview camera.
Disconnect the wiring harness by pressing the release tab and pulling it apart.
Inspect the connectors for corrosion or damage. If corroded, use electrical contact cleaner and a brush to clean the connectors.
Check the wiring for any signs of fraying or breaks. Repair or replace as necessary.

Step 4: Scan for Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port (usually located under the dashboard).
Turn on the ignition (without starting the engine) and run a diagnostic scan.
Note any trouble codes related to the camera or associated systems. If a relevant code is found, research it for specific troubleshooting steps.

Step 5: Test Camera Functionality

With the vehicle still in reverse, reconnect the wiring harness to the rearview camera.
Check if the camera display engages properly on the infotainment screen.
If the camera still does not work, further inspection may be required, possibly leading to a replacement camera.

Step 6: Replace the Camera (If Necessary)

If all previous steps confirm that the camera is faulty, proceed to replace it.
Remove the rear trim panel by using a trim removal tool and unscrewing any screws holding it in place.
Carefully detach the camera from its mount and disconnect the wiring harness.
Install the new rearview camera by reversing the removal steps and ensuring all connections are secure.
Reattach the rear trim panel.

Conclusion

After following these steps, the rearview camera should be operational. If issues persist, consult with a qualified technician or consider taking the vehicle to an authorized Toyota service center for further diagnostic and repair options.
