Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition turned off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller to remove the ABS fuse.
Inspect the fuse for continuity; replace it if blown with one of the same rating.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Inspect the fluid level; if low, top it off with the recommended brake fluid type (typically DOT 3 or DOT 4).
Check for any visible leaks in the brake system.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Inspect wiring and connectors for damage; clean the sensors if dirty.
If damaged, replace the sensors with new ones.

5. Brake System Inspection

Check the condition of the brake pads and rotors for excessive wear.
Replace worn pads or rotors as necessary.
Reassemble all components and lower the vehicle.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS trouble codes.
Start the vehicle and check if the ABS light remains off.
