Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Scan and Clear Codes

Using an OBD-II scanner, connect to the vehicle and retrieve any stored error codes.
Clear the codes and see if the traction control light re-illuminates after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris from the sensors using a soft cloth.
Check the wiring for any signs of damage or corrosion.
Reconnect the sensors securely.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, refill with the recommended brake fluid (DOT 3 or DOT 4 as per the owner's manual).
Check for any leaks in the brake lines or around the master cylinder.

5. Test Brake Pedal Switch

Locate the brake pedal switch above the brake pedal.
Use a multimeter to test the switch for continuity while pressing and releasing the brake pedal.
If defective, replace the switch with a new one.

6. Inspect ABS Module

Locate the ABS module under the hood.
Check for any visible signs of damage or corrosion on the module and its connectors.
If issues are found, consider replacing the ABS module.
