Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. OBD-II Code Clearing

Use the OBD-II scanner to clear any existing fault codes.
Reconnect the battery and start the vehicle to check if the warning light returns.

3. Inspect ABS Wheel Speed Sensors

Remove the wheel and tire assembly to gain access to the wheel speed sensors.
Clean any dirt or debris from the sensor area using a soft cloth.
Check the sensor harness for loose connections or fraying.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid type.
Check for any leaks in the brake lines.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity in the switch.
If faulty, replace the switch with a new one.

6. Reassemble and Road Test

Reinstall the wheel and tire assembly.
Lower the vehicle and drive it in various conditions to confirm the traction control system is functioning properly.
