Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris surrounding the sensors.
Disconnect the sensor connectors and inspect for corrosion or damage.
Clean the connectors and reconnect them securely.

3. Inspect and Replace Brake Fluid

Check the brake fluid reservoir level.
If low, top off with the manufacturer's recommended brake fluid (e.g., DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system:
1. Open the brake fluid reservoir cap and remove old fluid.
2. Bleed the brakes at each wheel until fresh fluid flows.
3. Refill the reservoir to the proper level and securely close the cap.

4. Examine ABS Module and Wiring

Locate the ABS module, typically near the brake master cylinder.
Inspect the module for signs of leaks or damage.
Check the wiring harness for fraying or loose connections.
If damaged, repair or replace the wiring as necessary.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity when pressed.
If the switch is faulty, replace it with a new one.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal and ensure it is secure.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the traction control light remains off.
