Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Reverse Bulbs

Remove the reverse light housing using the appropriate socket or screwdriver.
Check the bulbs for any signs of burnout; if burnt out, replace with new bulbs.
Reinstall the housing and test the reverse lights.

3. Camera Connection Check

Locate the rearview camera connector, usually found near the tailgate or trunk area.
Disconnect the camera harness and visually inspect for corrosion or damage.
Clean any corrosion with electrical contact cleaner, and reconnect securely.

4. Camera Lens Cleaning

If the lens is dirty, clean it using a microfiber cloth and appropriate cleaner.
Ensure no debris is obstructing the lens and that it is securely mounted.

5. Test Camera Power Supply

Reconnect the battery and turn the ignition to the "On" position without starting the engine.
Use a multimeter to check the voltage at the camera connector; it should read between 6-12 volts.
If the voltage is insufficient, trace the wiring back to find any breaks or shorts.

6. Final Assembly and Testing

Reassemble any panels or components removed during the inspection.
Start the vehicle and shift into reverse to test the camera functionality.
Monitor for any error messages or abnormal behavior.
