Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electronic components.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any debris or dirt from the sensors and their connectors.
Check the wiring for frays or corrosion and repair or replace as necessary.
Reconnect the sensors and ensure they are securely mounted.

3. Check Brake Fluid and ABS Module

Inspect the brake fluid reservoir; add fluid if low, using the recommended type (DOT 3 or DOT 4).
If the ABS module shows fault codes, follow manufacturer guidelines for resetting or replacing the module as necessary.

4. Verify Tire Condition and Pressure

Inspect all tires for uneven wear, damage, or low tread depth.
Inflate tires to the manufacturer's recommended pressure (usually found on a sticker inside the driver’s door).
If tires are worn out, replace them with approved specifications.

5. Test Traction Control System

Reconnect the negative battery terminal.
Start the vehicle and allow it to run for a few minutes.
Test drive the vehicle in a safe area to check if the traction control light remains off and the system functions correctly.
