- Tighten any loose bolts or replace damaged parts as necessary.
Tools Required: Socket set, wrenches.

4. Replace Brake Pedal Switch (if necessary)

Sub-steps:
- Locate the brake pedal switch, typically found near the top of the brake pedal assembly.
- Disconnect the wiring harness from the switch.
- Remove the switch from its mounting position.
- Install the new brake pedal switch and reconnect the wiring harness.
Tools Required: Screwdriver set.

5. Reconnect Battery and Test
