Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, basic hand tools.
Ensure the vehicle is on a flat surface and turn off the ignition before starting any work.

2. Inspect Wheel Speed Sensors

Remove the wheel and inspect the wheel speed sensor located near the brake rotor.
Clean the sensor and surrounding area to remove any debris.
Check the wiring harness for breaks or corrosion.
Reconnect the sensor and reassemble the wheel.

3. Check ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Inspect for any visible damage or loose connections.
If necessary, use a multimeter to test the power and ground connections.
If the module is faulty, replace it with a new unit and reprogram it as per manufacturer guidelines.

4. Inspect Brake System

Check the brake fluid level in the master cylinder reservoir.
Inspect the brake lines and hoses for any signs of leakage or damage.
If leaks are found, replace the affected components and bleed the brake system.

5. Electrical System Inspection

Inspect the battery terminals and cables for corrosion or loose connections.
Clean and tighten connections as needed.
Test the battery voltage with a multimeter; replace the battery if it is weak or failing.
