Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to cool down before starting work.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel (front and rear).
Remove the sensor mounting bolts using a socket set.
Carefully pull the sensor out, being cautious not to damage the connector.
Clean the sensor and the mounting area with an appropriate cleaner.
Reinstall the sensor and torque the bolts to the manufacturer's specifications (usually around 7-10 ft-lbs).

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the recommended brake fluid (typically DOT 3 or DOT 4).
Check for any leaks in the brake lines or around the master cylinder.

4. Inspect ABS Module and Wiring

Locate the ABS module, usually found near the brake master cylinder.
Inspect the wiring harness for any signs of wear or damage.
If necessary, clean any corrosion on the connectors with electrical contact cleaner.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing fault codes.
Start the vehicle and observe if the traction control light remains off.
