Solution

1. Preparation

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

2. Check and Replace ABS Fuse

Locate the fuse box; refer to the owner’s manual for the exact location.
Remove the ABS fuse using a fuse puller.
Inspect the fuse; replace it if it is blown.
Reinstall the fuse and reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Detach the sensor from its mounting, taking care not to damage the wiring.
Clean any dirt or debris from the sensor and the mounting surface.
Reinstall the sensor and secure it properly.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; add the appropriate type of brake fluid (DOT 3/4 as specified in the owner’s manual) if low.
Ensure there are no leaks from the brake lines or master cylinder.

5. Test and Replace Faulty Components

Use a multimeter to test the resistance of the wheel speed sensors; compare readings to specifications in the service manual.
If any sensor is out of specification, replace it with a new one.
If the ABS module is faulty, refer to the service manual for specific replacement and programming instructions.
