Solution

1. Preparation

Tools Required: Socket set, multimeter, screwdriver set.
Safety Warnings: Ensure the vehicle is in a secure position (parked on level ground) and the parking brake is engaged.

2. Inspect Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal arm.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity. Press the brake pedal and check for a closed circuit. If no continuity is detected, replace the switch.
Reconnect the switch after testing.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum marks on the reservoir. If low, top up with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake system.

4. Inspect Gear Shift Assembly

Remove the gear shift cover (if applicable) using a screwdriver.
Inspect the shift assembly for any obstructions or broken components.
Ensure the shift interlock mechanism is not jammed or malfunctioning.

5. Test Battery and Electrical Connections

Use a multimeter to measure the battery voltage; it should be around 12.6 volts when the engine is off.
Check battery terminals for corrosion and tight connections. Clean and secure them if needed.
