Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
Check the sensor wiring for frays or damage; repair or replace as necessary.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, use the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) to refill to the proper level.
If the fluid appears contaminated, proceed to replace the brake fluid as part of a brake system flush.

4. Inspect ABS Module and Connections

Locate the ABS module in the engine bay.
Visually inspect the module for any signs of corrosion or damage.
Ensure all electrical connections are secure; reseat any loose connectors.

5. Test Traction Control Switch

Reconnect the battery terminal.
Start the engine and attempt to toggle the traction control switch on and off.
Observe the dashboard for any change in the traction control light status.

6. Clear Error Codes

Use the OBD-II scanner to clear any stored fault codes related to the traction control system.
Test drive the vehicle to confirm the issue is resolved.
