Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the ignition is off before starting the repair.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to read and clear the error codes.
Disconnect the scanner after completing this step.

3. Inspect Wheel Speed Sensors

Tools Required: Socket set.
Locate each wheel speed sensor and visually inspect for damage or dirt.
If dirty, clean the sensor with a soft cloth or compressed air.
If damaged, replace the wheel speed sensor with a new one.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is between the "MIN" and "MAX" markings.
If low, top off with the specified brake fluid type (DOT 3 or DOT 4 as per the owner's manual).

5. Inspect Wiring and Connectors

Examine the wiring harness and connectors associated with the traction control and ABS systems.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring or connectors.

6. Test Drive

Start the vehicle and conduct a test drive to ensure the traction control system is functioning correctly.
Monitor the dashboard for any warning lights reappearing during the drive.
