Solution

1. Preparation

Gather tools and safety equipment (gloves, safety glasses).
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Record any trouble codes related to the traction control system.
Clear the codes and observe if the traction control light returns after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connector from each sensor.
Using a multimeter, check the resistance of each sensor; they should typically read between 1,000 to 2,000 ohms.
Clean any dirt or debris from the sensor and mounting area.
Reconnect the sensors ensuring proper fit.

4. Check Brake System

Inspect brake fluid levels and condition in the master cylinder.
Verify that the brake pads and rotors are in good condition.
If the brake warning light is also illuminated, check for faults in the brake system.

5. Inspect ABS Module

Locate the ABS control module, usually near the engine bay.
Check for any loose connections or corrosion on the wiring harness.
If issues are suspected, consult the service manual for further testing procedures or consider replacement.

6. Reconnect Battery

After completing inspections and repairs, reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
