Solution

1. Preparation

Gather tools and parts before starting.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if it has been running.

2. Check and Replace the ABS Fuse

Locate the fuse box (usually found under the dashboard or under the hood).
Identify the ABS fuse using the diagram located on the fuse box cover.
Use a fuse puller to remove the fuse and inspect it. Replace it if blown.
Reconnect the fuse and battery terminal.

3. Inspect and Clean ABS Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the sensor wiring harness.
Clean the sensor and the area around it with brake cleaner to remove dirt and debris.
Reconnect the sensor and check for any visible damage.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum markers.
If low, top off with the correct type of brake fluid (usually DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks in the brake lines and connections.

5. Inspect ABS Module Wiring

Follow the wiring from the ABS module to the wheel speed sensors.
Look for any frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors.

6. Reset the ABS Light

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.
