Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid any electrical shorts during repairs.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
If necessary, unbolt the sensors using a socket set and inspect for damage.
Reinstall the sensors and ensure they are securely fastened.

3. Test and Replace Brake Light Switch

Locate the brake light switch, typically situated near the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If the switch is faulty, remove it by unscrewing or unclipping it and replace it with a new one.

4. Inspect ABS Module Connections

Locate the ABS module, usually found near the master cylinder.
Check for loose or corroded electrical connectors.
Clean any corrosion with electrical cleaner and reconnect securely.

5. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any fault codes from the system.
Start the vehicle and check if the traction control light remains illuminated.
