Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Check Wheel Speed Sensors

Remove the wheel from the affected corner.
Inspect the wheel speed sensor for dirt or damage; clean or replace as necessary.
Reinstall the wheel and torque lug nuts to manufacturer specifications.

3. Inspect Brake Fluid and ABS Module

Open the hood and check the brake fluid reservoir; top off if low with appropriate brake fluid type.
Visually inspect the ABS module for any loose or corroded connections; clean or secure as needed.

4. Test Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Use a multimeter to test the switch for continuity; replace if faulty.

5. Tire Inspection

Check all tires for uniform tread depth and proper inflation.
Replace any mismatched or severely worn tires to ensure consistent traction.
