Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent any electrical shock or short circuits.

2. Inspect Wheel Speed Sensors

Remove the wheel for better access using a socket set.
Locate the wheel speed sensor on each wheel assembly.
Clean the sensor and connectors with electrical contact cleaner.
If damaged, replace the wheel speed sensor with a new one.

3. Check ABS Module and Wiring

Locate the ABS module, usually near the master cylinder in the engine bay.
Inspect wiring harnesses for frayed wires or loose connections.
If issues are found, repair or replace the damaged wiring or connectors.

4. Verify Tire Condition and Pressure

Use a tire pressure gauge to check the pressure of all tires.
Ensure all tires are inflated to the manufacturer’s recommended pressure found in the owner’s manual or door jamb.
Inspect tires for uneven wear or damage; replace if necessary.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new component.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal and tighten securely.
Use the OBD-II scanner to clear any error codes and reset the traction control system.
Test the vehicle to ensure the traction control light is no longer illuminated.
