Solution

1. Preparation

Gather all required tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Check ABS Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity. Replace if blown.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Clean the sensor and the area around it to remove debris.
Reconnect and ensure the wiring is intact and not damaged. Repeat for all wheels.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the MIN and MAX marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect for any leaks in the brake line.

5. Reset ABS Light

Reconnect the battery's negative terminal.
Start the vehicle and use the OBD-II scanner to clear any stored ABS codes.
Check if the ABS light remains off after clearing codes.
