Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools: OBD-II scanner, socket set, multimeter, and cleaning supplies.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor wiring harness.
Remove the sensor (usually held by a bolt).
Clean the sensor and mounting area with brake cleaner.
Reinstall the sensor and secure it with the bolt. Torque to the manufacturer's specifications.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid.
Check for any signs of leaks in the brake lines or around the master cylinder.

4. Verify Tire Condition

Check each tire for tread depth and even wear.
Inflate tires to the recommended PSI as per the owner’s manual.
Replace any tires that are excessively worn or damaged.

5. 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 one.
