Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.

2. Inspect and Replace Brake Light Bulbs

Sub-steps:
1. Open the trunk and locate the taillight assembly.
2. Remove the access panel if necessary to reach the bulbs.
3. Twist the bulb socket counterclockwise and pull it out.
4. Inspect the bulb for damage; replace it if burned out with a new bulb of the same specification (typically 1157 for brake lights).
5. Reinsert the bulb socket and twist it clockwise to secure.

3. Check and Replace Brake Light Fuse

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Remove the cover and identify the brake light fuse (refer to the fuse diagram on the cover).
3. Use a fuse puller or pliers to extract the fuse and check for continuity.
4. If blown, replace it with a new fuse of the same amperage (typically 10A).
5. Reinstall the fuse cover.

4. Test and Replace Brake Light Switch (if necessary)

Sub-steps:
1. Locate the brake light switch, usually found above the brake pedal.
2. Disconnect the wiring harness from the switch.
3. Use a multimeter to test the switch for continuity when the brake pedal is pressed.
4. If no continuity is detected, remove the switch by unscrewing it and replace it with a new one.
5. Reconnect the wiring harness and ensure it is secure.

5. Inspect Wiring Harness

Sub-steps:
1. Visually inspect the wiring harness leading to the rear lights for any frays or disconnections.
2. Repair any damaged wires using electrical tape or replace sections of wiring as needed.
3. Ensure all connectors are seated properly and free from corrosion.
