Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off before starting work.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and document any error codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors and the area around them.
Check for physical damage or loose connections.

4. Check ABS Module

Locate the ABS control module, typically found near the brake master cylinder.
Inspect the module for any signs of corrosion or damage.
If applicable, clear any stored codes using the OBD-II scanner and test drive to see if the light reappears.

5. Inspect Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; it should be between the minimum and maximum marks.
If low, top off with the manufacturer-recommended brake fluid type.
