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 issues.

2. Check and Replace ABS Fuse

Locate the fuse box under the dashboard or hood.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for damage.
If blown, replace it with a fuse of the same amperage rating.

3. Inspect Wheel Speed Sensors

Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Check the sensor for dirt or damage. Clean with a soft cloth if necessary.
Ensure the sensor connector is securely plugged in. Repair or replace if damaged.

4. Check Brake Fluid Level

Locate the brake fluid reservoir in the engine bay.
Check the fluid level; it should be between the "MIN" and "MAX" markings.
If low, top off with the recommended brake fluid (usually DOT 4 or as specified in the owner's manual).

5. Test ABS Module and Pump

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Listen for the ABS pump operation; it should engage briefly.
If no sound is heard, further testing of the ABS module may be needed with specialized equipment.
