Solution

1. Preparation

Gather all 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. Scan for Fault Codes

Use an OBD-II scanner to retrieve any stored error codes.
Document the codes for further diagnosis.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any debris or dirt from the sensors.
Check the wiring harness for fraying or disconnection.
If damaged, replace the sensors with OEM parts.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid level is above the minimum mark.
If low, top off with manufacturer-recommended brake fluid.

5. Inspect Tires

Check all four tires for even wear and proper inflation.
Replace any tires that are excessively worn or mismatched.
Ensure all tires are inflated to the recommended pressure.

6. Test Traction Control Switch

Locate the traction control button on the dashboard.
Press the button to see if the light turns off.
If it remains illuminated, inspect the wiring and replace the switch if necessary.
