Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean the sensors with a suitable cleaner to remove any debris or dirt.
Check wiring connections for any signs of damage or corrosion.
Reconnect any loose connections and ensure they are secure.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top up with the manufacturer-recommended brake fluid.
If the fluid is contaminated, consider flushing the brake system.

4. Inspect ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Check the module for any visible signs of leaks or electrical damage.
Use a multimeter to test the ABS module’s power and ground circuits.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Using a multimeter, test the switch for continuity when engaged.
If the switch is faulty, replace it with a new component.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored traction control error codes.
Start the vehicle and check if the traction control warning light remains off.
