Solution

1. Preparation

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

2. Check Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris obstructing the sensor.
Inspect the wiring for cracks or frays.
Reconnect any loose connections and secure the wiring.

3. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the brake lines for leaks or damage; replace any 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.
If faulty, replace the switch with a new OEM part.

5. Tire Inspection

Check all four tires for uneven wear patterns.
Measure the tread depth; replace tires if below the manufacturer's specifications.
Ensure all tires are properly inflated according to the vehicle's specifications.
