Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and basic hand tools.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Diagnostic Scan

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and record any stored trouble codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connectors and visually inspect the sensors for dirt or damage.
Use a multimeter to test the sensors' resistance; replace if readings are outside manufacturer's specifications.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Look for any signs of leaks around the brake lines or calipers.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch’s continuity when pressed. Replace if faulty.
