Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface with the engine off.
Tools required: OBD-II scanner, multimeter, socket set, torque wrench, and safety goggles.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (do not start the engine).
Record any stored ABS-related error codes and refer to the service manual for specific issues.

3. Inspect and Replace Components

A. Check ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect it; replace if blown.

B. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub; visually inspect for damage or disconnection.
If damaged, remove the sensor using a socket set and replace it with a new one.

C. Inspect ABS Module and Wiring

Check the wiring harness connected to the ABS module for signs of corrosion or loose connections.
If any wiring is damaged, repair or replace as necessary.

4. Brake Fluid Check

Locate the brake fluid reservoir and check the fluid level; top off with the recommended type of brake fluid if low.
Inspect the fluid for contamination; replace fluid if it appears dark or has debris.

5. Reassemble and Test

Reinstall any components removed during inspection.
Lower the vehicle and ensure all tools are removed from the engine bay.
Start the vehicle and check if the ABS light has turned off.
