Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire assembly to access the wheel speed sensors.
Disconnect the electrical connector for each wheel speed sensor.
Use a multimeter to check the resistance; it should typically be between 1,000 to 2,000 ohms. Replace any faulty sensor.
Clean any dirt or debris from the sensor area before reinstallation.

3. Check Brake Fluid and System

Inspect the brake fluid reservoir; ensure fluid is at the appropriate level.
Look for any leaks around brake lines, calipers, and hoses.
If leaks are found, replace damaged components and bleed the brakes to remove air.

4. Verify Traction Control Switch

Check the operation of the traction control switch located on the dashboard.
Ensure it is not stuck or damaged; replace the switch if necessary.

5. Inspect ABS Module

Tools Required: OBD-II scanner
Use the scanner to check for error codes related to the ABS system.
If codes indicate a fault, inspect the ABS module and wiring for issues.
Replace the ABS module if it shows signs of failure or damage.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light remains illuminated.
Test the operation of the traction control system by driving the vehicle in a controlled environment.
