Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box (consult the owner’s manual for exact location).
Remove the ABS fuse and check for continuity using a multimeter.
If blown, replace the fuse with one of the same amperage.

3. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors (one per wheel).
Check for any physical damage to the sensors or their wiring.
Reconnect any loose connectors; replace damaged sensors as necessary.

4. Test ABS Module

Reconnect the battery.
Use an OBD-II scanner to clear any existing ABS codes.
Start the vehicle and perform a test drive to check if the ABS light remains off.
If the light persists, test the ABS module for proper voltage and ground using a multimeter.

5. Check Brake Fluid Level

Locate the brake fluid reservoir.
Ensure the fluid level is within the recommended range; add fluid if necessary.
Inspect for any leaks in the brake lines or calipers.
