Solution

1. Preparation

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

2. Check and Replace ABS Fuses

Tools Required: Fuse puller or pliers.
Locate the fuse box and identify the ABS fuses using the diagram on the lid.
Remove the ABS fuse and inspect for continuity using a multimeter.
If blown, replace with a fuse of the same amperage rating.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, and brake cleaner.
Raise the vehicle on jack stands and remove the wheels to access the wheel speed sensors.
Disconnect the sensor connectors and inspect the wiring for damage.
Clean the sensors with a brush and brake cleaner to remove any debris or buildup.
Reconnect the sensors securely.

4. Check Brake Fluid Level

Tools Required: Clean rag.
Locate the master cylinder reservoir and check the brake fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Check for any leaks in the brake lines or around the master cylinder.

5. Reset ABS System

Tools Required: OBD-II scanner.
After addressing any issues found, reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored ABS fault codes.
Verify that the ABS light turns off after clearing codes.
