Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connector by gently pulling it apart.
Clean the sensor and surrounding area using an appropriate cleaning solution.
Reconnect the sensor and ensure it is securely fastened.

3. Check Tire Condition and Pressure

Inspect all tires for signs of wear, damage, or improper inflation.
Inflate tires to the manufacturer’s recommended pressure, typically found on the driver’s side door jamb.
Replace any tires that are excessively worn or damaged.

4. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is below the minimum mark, top it up with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the reservoir for leaks or cracks.

5. Reset Traction Control System

With the battery reconnected, turn on the ignition without starting the engine.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and allow the vehicle to run for a few minutes to see if the traction control light turns off.
