Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on the electrical system.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors near each wheel hub.
Clean any debris or dirt from the sensors and their connectors.
Check the wiring harness for signs of wear or damage.
If damaged, replace the wheel speed sensors.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with the recommended brake fluid type (usually DOT 4).
If the fluid is contaminated, perform a brake fluid flush and refill.

4. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Inspect the module and its wiring for corrosion, loose connections, or physical damage.
If damaged, replace the ABS module.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is activated.
If faulty, replace the traction control switch.

6. Reconnect Battery and Reset System

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any stored fault codes.
Start the vehicle and check if the traction control light remains off.
