Solution

1. Preparation

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

2. Inspect and Replace Bulbs

Sub-steps:
1. Open the trunk and locate the access panel behind the tail lights.
2. Remove the access panel to gain access to the rear light assembly.
3. Twist and remove the bulb sockets from the tail light assembly.
4. Inspect each bulb for filament damage and replace any burned-out bulbs with new ones.
5. Reinsert the bulb sockets and replace the access panel.

3. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box (usually found under the dashboard or in the engine compartment).
2. Refer to the owner’s manual to identify the specific fuses for the tail lights and turn signals.
3. Remove the fuse with a fuse puller and inspect it for continuity.
4. Replace any blown fuses with ones of the same amperage rating.

4. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect the wiring harnesses leading to the rear lights for any signs of wear, corrosion, or damage.
2. Check connectors for tightness and clean any corrosion with electrical contact cleaner.
3. Repair or replace any damaged wires or connectors.

5. Test Electrical Supply

Sub-steps:
1. Set the multimeter to measure DC voltage.
2. With the ignition on, probe the light socket terminals to check for voltage.
3. If no voltage is present, trace the wiring back to the fuse box and check for continuity.
4. Repair any broken connections as needed.
