Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery negative terminal to prevent any electrical issues.

2. Inspect and Repair

ABS Sensor Inspection:
- Locate the ABS wheel speed sensors on each wheel.
- Remove the wheel for better access if necessary.
- Inspect each sensor for dirt, damage, or corrosion.
- Clean the sensors with a soft cloth and check electrical connections.
Wiring Check:
- Follow the wiring from each sensor back to the ABS module.
- Look for any frayed wires or loose connections and repair them as needed.

3. Brake Fluid Check

Reconnect the battery terminal and check the brake fluid level.
If low, top off with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is dark or contaminated, consider flushing the brake system.

4. Use OBD-II Scanner

Reconnect the OBD-II scanner to the vehicle’s diagnostic port.
Clear the ABS codes from the system.
Verify that the ABS light goes off after codes are cleared.

5. Final Inspection

Take the vehicle for a test drive to ensure that the ABS light remains off.
Monitor the braking system for any irregularities during the drive.
