Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner instructions to read and record any error codes.
Clear the error codes and disconnect the scanner.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt from the sensors.
Check the sensor wiring for frays or breaks.
If faulty, replace the wheel speed sensors with OEM parts.

4. Check Traction Control Switch

Locate the traction control switch on the dashboard.
Ensure the switch is not stuck in the "off" position.
If the switch is malfunctioning, replace it with an OEM part.

5. Brake System Inspection

Check the brake fluid level in the master cylinder reservoir.
Inspect brake pads and rotors for wear, ensuring proper operation of the ABS system.
If necessary, replace worn brake components.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
Start the vehicle and check if the traction control light remains illuminated.
