Repair Instructions

Step 1: Verify Vehicle Systems

Turn on the Ignition:
- With the vehicle in the "ON" position but not running, turn on the infotainment system.
Activate Reverse:
- Shift the vehicle into reverse and check for camera activation.

Step 2: Check for DTCs

Connect OBD-II Scanner:
- Plug in the scanner to the OBD-II port (usually located under the dashboard).
Retrieve Codes:
- Follow the scanner instructions to read any DTCs. Pay particular attention to codes related to the camera system, such as U0401, U0121, or any related to the multimedia system.
Clear Codes:
- If codes are present, clear them and test the system again to see if the issue reoccurs.

Step 3: Inspect Wiring and Connections

Access the Rearview Camera:
- Open the trunk and remove any trim panels or covers to access the camera wiring and connectors.
Check Connections:
- Ensure the camera's electrical connector is securely attached. Disconnect and reconnect it to ensure a good connection.
Inspect for Damage:
- Look for damaged wires, corrosion, or loose connections along the camera wiring harness.

Step 4: Test the Camera

Use a Multimeter:
- Set the multimeter to measure voltage.
- With the vehicle in reverse, check for voltage at the camera connector. Refer to the vehicle wiring diagram for the correct pinout.
Replace the Camera:
- If there is no voltage or the camera is non-responsive, consider replacing the rearview camera.
- Remove the old camera by unscrewing it from its mounting bracket and disconnecting the wiring harness.
- Install the new camera by reversing the removal steps.

Step 5: Reassemble and Test

Reassemble Trim Panels:
- Ensure all trim panels are secured properly before closing the trunk.
Final Test:
- Start the vehicle and shift into reverse to check if the rearview camera is functioning properly.

Conclusion

If the rearview camera still does not work after following these steps, it may be necessary to consult with a professional technician or visit a Toyota dealership for further diagnosis, as the issue may reside within the infotainment system or require specialized equipment for repair.
