Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, and replacement bulbs if necessary.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Replace Reverse Light Bulbs

Open the trunk and locate the reverse light assembly.
Remove the retaining screws or clips to access the bulb socket.
Twist and pull the bulb socket out of the assembly.
Replace the old bulb with a new bulb (check for proper wattage).
Reassemble the light assembly and secure it back in place.

3. Check and Replace the Reverse Light Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the reverse light fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it appears blown.

4. Test the Reverse Light Switch

Locate the reverse light switch on the transmission.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity when the switch is activated (shifting into reverse).
Replace the switch if it does not provide continuity.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors leading to the reverse lights for fraying, corrosion, or loose connections.
Repair or replace damaged wiring and connectors as necessary.
