Fixing the Rearview Camera Not Displaying in a 2021 Toyota Highlander

When the rearview camera is not displaying on your 2021 Toyota Highlander, it can be caused by various issues, ranging from simple software glitches to wiring problems. Below are detailed steps to diagnose and fix the issue.

Tools Required
  • OBD-II scanner (optional for checking error codes)
  • Phillips screwdriver
  • Flathead screwdriver
  • Multimeter
  • Wiring diagram for the rearview camera system
  • Torx screwdriver set
  • Electrical contact cleaner
  • Wire splicing kit (if needed)
Repair Instructions

  1. Inspect Wiring and Connections

    • Access the Rearview Camera:
      • Open the rear hatch and locate the rearview camera assembly.
      • Use a Phillips screwdriver or a Torx screwdriver to remove the camera housing.
    • Check Electrical Connections:
      • Disconnect the camera connector and inspect for corrosion or damage.
      • Use a multimeter to test for voltage at the connector while the vehicle is in reverse (should have 12V).
    • Repair or Replace Wiring:
      • If damaged, repair the wiring using a wire splicing kit or replace the camera with a new one.

  2. Inspect Infotainment System Connections

    • Access the Infotainment Unit:
      • Carefully remove the trim panel around the infotainment system with a flathead screwdriver.
      • Remove screws holding the unit in place and gently pull it out.
    • Check Connections:
      • Ensure that the camera input connector is securely plugged into the back of the infotainment unit.
      • Look for any signs of damage or corrosion.
    • Reassemble: Once connections are checked and any issues addressed, reassemble the infotainment unit and trim.

  3. Reset the Infotainment System

    • If the camera still does not display, perform a system reset:
      • Disconnect the vehicle battery for about 10-15 minutes to reset the infotainment system.
      • Reconnect the battery and check if the camera displays when the vehicle is in reverse.

  4. Reprogram the Camera (if applicable)

    • In some cases, the camera may need to be reprogrammed using specialized diagnostic tools. This step is typically done at a dealership or professional service center.

  5. Test the System

    • Reinstall everything and ensure all components are securely fastened.
    • Start the vehicle, shift into reverse, and check if the rearview camera is functioning properly.
Conclusion

If after following these steps the rearview camera still does not display, it may indicate a more serious issue with the infotainment system or the camera module itself, which may require professional diagnostic tools and expertise. Consider visiting a Toyota dealership or a certified automotive technician for further assistance.
