Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to ensure electrical safety.

2. Check Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris from the sensors with a soft cloth.
Inspect the wiring for any signs of fraying or damage.
Reconnect any loose connections.

3. Inspect Brake Fluid and System

Check the brake fluid reservoir for proper levels; if low, top up with the recommended brake fluid type.
Inspect for any leaks in the brake lines or around the master cylinder.
If any leaks are found, repair or replace the affected components.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it does not show continuity.

5. Tire Inspection

Visually inspect all tires for uneven wear patterns that may affect traction.
Check tire pressure and inflate to the manufacturer's specifications if necessary.
Replace any damaged or excessively worn tires.
