Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the vehicle to cool down if it has been running.

2. Scan and Clear Codes

Use the OBD-II scanner to scan for any error codes related to the traction control system.
Document the codes for reference.
Clear the codes and check if the traction control light returns after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors and connectors.
Use a multimeter to check for continuity and proper voltage output when the vehicle is in motion.
Replace any faulty sensors with new ones.

4. Check ABS Module

Inspect the ABS module connections for any corrosion or loose wiring.
Test the ABS pump operation by activating the system using a scan tool.
If the ABS module is faulty, replace it following the manufacturer's guidelines.

5. Examine Tire Conditions

Check all tires for proper tread depth and even wear.
Ensure that all tires are inflated to the recommended pressure.
Replace any damaged or excessively worn tires.
