Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box under the dashboard or hood.
Remove the ABS fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Check and Repair Wheel Speed Sensors

Lift the vehicle using a jack and support it with jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor for physical damage or dirt; clean or replace as necessary.
Measure the sensor's resistance using a multimeter (typically should be between 1,000 - 2,500 ohms).
Reinstall the wheel and lower the vehicle.

4. Inspect ABS Control Module Connections

Access the ABS control module, usually located near the brake master cylinder.
Disconnect the wiring harness and inspect for corrosion or damage.
Clean connections using electrical contact cleaner; reconnect securely.

5. Final Steps

Reconnect the battery.
Clear any diagnostic trouble codes using the OBD-II scanner.
