Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box under the dashboard or engine compartment.
Remove the ABS fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.
Reinstall the fuse and reconnect the battery terminal.

3. Inspect and Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the electrical connector from the sensor.
Remove the sensor from the hub using a socket or wrench.
Inspect the sensor for damage or dirt; clean or replace if necessary.
Reinstall the new or cleaned sensor and reconnect the electrical connector.
Repeat for all wheels if necessary.

4. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Check the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the reservoir cap securely.

5. Reset ABS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes related to the ABS system.
Perform a test drive to ensure the ABS light does not reappear.
