Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush
Remove the wheel on the affected side to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Use a multimeter to check the sensor's resistance; it should typically range from 800 to 2,000 ohms.
Clean the sensor and surrounding area to remove dirt and debris, then reconnect.

3. Check Brake Fluid and ABS Module

Tools Required: Brake fluid tester, wrench
Inspect the brake fluid reservoir for proper fluid level; refill with DOT 3 or DOT 4 brake fluid if low.
Check for leaks in the brake lines or around the ABS module.
If leaks are found, replace the affected components and bleed the brakes.

4. Inspect Traction Control Module

Tools Required: Torx screwdriver, multimeter
Locate the traction control module, typically near the ABS module.
Disconnect the module's electrical connector and inspect for corrosion or loose connections.
Clean the connectors with an electrical contact cleaner and reconnect.

5. Test Drive and System Reset

Reconnect the battery.
Start the vehicle and perform a test drive to ensure the traction control light is off and the system is functioning correctly.
If the light remains on, consider resetting the system using the OBD-II scanner.
