Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate each wheel speed sensor (usually mounted near the brake caliper).
Remove the sensor from its mount using a socket set.
Clean the sensor and mounting area with a brake cleaner.
Reinstall the sensor and ensure it is securely fastened.

3. Replace Faulty ABS Fuse

Locate the fuse box (refer to the owner’s manual for the specific location).
Identify the ABS fuse using the fuse layout diagram.
Remove the fuse using fuse pullers or pliers.
Replace it with a new fuse of the same amperage.

4. Check Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level and check for contamination.
If low, add the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
If contaminated, perform a complete brake fluid flush.

5. Test ABS Control Module

Use a multimeter to check the voltage at the ABS control module connector.
Ensure the electrical connectors are clean and free of corrosion.
If the module is faulty, replace it with a new or refurbished unit.
