Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, isopropyl alcohol.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Clean the sensor using a brush and isopropyl alcohol to remove dirt and debris.
Reinstall the sensor and reconnect the wiring harness.
Reattach the wheel and lower the vehicle.

3. Check Brake Fluid Level and System

Tools Required: Brake fluid (as needed), funnel.
Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, fill with the manufacturer's recommended brake fluid.
Inspect brake lines and connections for leaks; repair or replace as necessary.

4. Replace ABS Fuse (if necessary)

Tools Required: Fuse puller or pliers.
Locate the fuse box and identify the ABS fuse using the diagram.
Remove the fuse and inspect it for continuity; replace with the same amperage if blown.

5. Test ABS Module

Tools Required: Multimeter.
Locate the ABS control module, typically near the master cylinder.
Use the multimeter to check for power and ground at the module.
If there is no power, trace the wiring back to the fuse box.
