Repair Instructions

Step 1: Clean the Camera Lens

Locate the Camera: The rearview camera is typically located on the trunk or the rear bumper.
Clean the Lens: Use a mild cleaner and a soft cloth to gently clean the camera lens. Remove any dirt or debris that may obstruct the view.

Inspect for Damage:
- Look for frayed wires or broken connections. Repair any damaged wiring with electrical tape or by replacing the harness if necessary.

Step 3: Check for Software Updates

Check for Updates:
- Visit the official Toyota website or consult your owner's manual for instructions on how to update the infotainment system.
- Follow the update procedures carefully to ensure the software is current.

Step 4: Test the Camera System

- If the camera is determined to be faulty, remove the screws or clips holding the camera in place.
- Disconnect the wiring harness.
Install the New Camera:
- Connect the new camera to the wiring harness.
- Secure the camera in place with screws or clips.
Reassemble the Trim:
