Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Inspect and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and check for continuity; replace it if blown.
Reinstall the new fuse and reconnect the battery.

3. Test and Replace Wheel Speed Sensors

Raise the vehicle and remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector and inspect the wiring for damage.
Use a multimeter to test the sensor’s resistance; replace it if it is out of specifications.
Reinstall the new sensor, reconnect the electrical connector, and secure the wheel.

4. Check and Refill Brake Fluid

Open the brake fluid reservoir cap and inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid (e.g., DOT 4).
Replace the reservoir cap securely.

5. Inspect ABS Control Module

Locate the ABS control module and visually inspect for corrosion or damage.
If issues are found, replace the ABS control module according to manufacturer specifications.
Reconnect any electrical connectors and ensure all ground connections are clean.
