Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shock while working on the vehicle.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors, usually found near the brake caliper or on the wheel hub.
Remove any dirt or debris from the sensors using a clean, dry cloth.
If damaged, proceed to replace the sensors with new ones.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir and check the fluid level.
If low, top off with manufacturer's specified brake fluid (usually DOT 4).
If contaminated, drain the old fluid and replace it with fresh fluid, bleeding the brakes afterwards.

4. Inspect and Calibrate Steering Angle Sensor

Use a diagnostic scan tool to check if the steering angle sensor is functioning properly.
If calibration is needed, follow the manufacturer's calibration procedure, which usually involves turning the steering wheel from lock to lock and resetting the sensor via the scan tool.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
If the light is off, the issue is resolved; if not, further diagnostics may be required.
