Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel to access the wheel speed sensors.
Unplug the sensor connector and inspect for physical damage or dirt.
Use a multimeter to test the sensor's resistance; replace if outside manufacturer specifications.

3. Check ABS Module

Locate the ABS module, typically near the brake master cylinder.
Inspect the wiring harness and connectors for signs of wear or corrosion.
Clean any corrosion with electrical contact cleaner.
If necessary, replace the ABS module following manufacturer guidelines.

4. Tire Inspection and Adjustment

Visually inspect all tires for uneven wear or damage.
Use a tire pressure gauge to check tire pressures and adjust to the manufacturer's recommended values.
Replace any tires that are excessively worn or damaged.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and check if the traction control light remains off.
