Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Bulbs

Remove the brake light assembly by unscrewing the retaining screws.
Carefully pull out the bulb socket from the assembly.
Remove old bulbs and replace with new ones (ensure correct wattage).
Reinstall the bulb socket and brake light assembly.

3. Check and Replace Fuse

Locate the fuse box (usually under the dashboard on the driver’s side or in the engine compartment).
Identify the brake light fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

4. Inspect and Replace Brake Pedal Switch

Locate the brake pedal switch directly above the brake pedal.
Disconnect the electrical connector from the switch.
Test the switch using a multimeter; it should show continuity when the pedal is pressed.
If faulty, remove the switch by unscrewing it or pulling it from its mounting bracket.
Install the new switch and reconnect the electrical connector.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the brake lights by pressing the brake pedal to ensure they illuminate properly.
