Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a flat surface and ensure it is secure.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually in the engine compartment or under the dashboard).
Remove the fuse for the ABS using a fuse puller or pliers.
Check the fuse for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage.

3. Check ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor wiring connector.
Inspect the sensor and its wiring for damage or dirt.
Clean the sensor and connector with electrical contact cleaner.
Reconnect the sensor securely.

4. Brake Fluid Inspection

Locate the brake fluid reservoir under the hood.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
If the fluid is dirty, consider a complete brake fluid flush.

5. 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 observe if the ABS light turns off.
