Fixing a Malfunctioning Rearview Camera in a 2020 Toyota Highlander
Tools Required
  • OBD-II Scanner
  • Multimeter
  • Screwdrivers (Phillips and flathead)
  • Trim removal tools
  • Wire crimping tool (if needed)
  • Replacement camera (if necessary)
  • Electrical contact cleaner

Repair Instructions

Step 1: Inspect the Camera

  1. Locate the Camera:

    • The rearview camera is typically mounted near the license plate area.

  2. Remove the Camera:

    • Use a flathead screwdriver to carefully pry off any trim covering the camera.
    • Unscrew the camera from its mount and disconnect the wiring harness.

  3. Check the Lens:

    • Clean the lens with a soft cloth and glass cleaner if it’s dirty.
    • Inspect for cracks or damage. If damaged, replace the camera.
Step 2: Check Wiring and Connectors

  1. Inspect the Wiring:

    • Look for frayed wires or loose connections in the wiring harness.
    • Use a multimeter to check for continuity in the wiring. If any wires are damaged, repair or replace them.

  2. Clean Connectors:

    • Use electrical contact cleaner to clean the camera connector and any associated connectors.
    • Ensure the connectors are seated properly when reassembling.
Step 3: Check the Fuse

  1. Locate the Fuse Box:

    • The fuse box is typically located under the dashboard or in the engine compartment.

  2. Identify the Correct Fuse:

    • Refer to the owner’s manual to find the specific fuse for the rearview camera.

  3. Inspect the Fuse:

    • Pull out the fuse and check if the filament is intact. If the fuse is blown, replace it with one of the same amperage.
Step 4: Reassemble and Test

  1. Reinstall the Camera:

    • Reconnect the wiring harness to the rearview camera.
    • Secure the camera back into its mounting location and replace any trim panels.

  2. Start the Vehicle:

    • Start the vehicle and shift into reverse.
    • Check if the rearview camera display appears correctly.
Step 5: Clear Fault Codes (if applicable)
  1. Use the OBD-II Scanner:
    • Clear any stored fault codes related to the camera system.
    • Perform a test drive to see if the issue reoccurs.

Conclusion

If the rearview camera still does not function after completing these steps, the issue may be with the infotainment system or a deeper electrical problem. In that case, it may be necessary to consult a professional technician or visit a Toyota dealership for further diagnosis.
