why does my Toyota Highlander Third Generation (2014-2019) backup camera show a black screen

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the vehicle’s battery to prevent electrical shock.

2. Clean Camera Lens

• Locate the backup camera, typically mounted on the rear liftgate or bumper.
• Use a soft cloth and mild cleaning solution to gently clean the camera lens.
• Inspect for physical damage; if damaged, proceed to replace the camera.

3. Inspect Fuse

• Locate the vehicle's fuse box (refer to the owner’s manual for location).
• Remove the fuse related to the backup camera (check the fuse diagram).
• Inspect the fuse for continuity; replace it if blown with the same amperage rating.

4. Check Wiring Connections

• Remove any covers or panels to access the wiring harness for the backup camera.
• Visually inspect the connectors for corrosion, broken pins, or loose connections.
• Clean any corroded connectors with electrical contact cleaner; reconnect securely.

5. Test Power Supply

• Reconnect the battery.
• Put the vehicle in reverse and use a multimeter to test for voltage at the camera connector.
• If no voltage is present, trace wiring back to the source to identify potential breaks or shorts.

6. Replace Camera (if necessary)

• If all previous steps are clear and the camera still does not function, replace the backup camera.
• Disconnect the wiring harness from the old camera.
• Remove the old camera using appropriate socket size (usually Torx or Phillips).
• Install the new camera by reversing the removal steps and reconnecting the wiring harness.
