Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensors using a soft cloth or compressed air.
If sensors are damaged, replace them with new ones.
Reconnect any loose wiring harnesses to the sensors.

3. Check Traction Control Switch

Locate the traction control switch on the dashboard.
Test the switch for functionality using a multimeter.
If faulty, remove the switch and replace it with a new one.

4. Inspect Brake System

Remove the wheel to access the brake assembly.
Inspect brake lines and ABS components for leaks or damage.
If issues are found, replace defective brake components as necessary.
