Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, and replacement fuses or sensors if needed.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any error codes related to the ABS system.

3. Inspect Fuses

Locate the fuse box (refer to owner’s manual).
Remove the ABS-related fuses using a fuse puller or pliers.
Visually inspect fuses; replace any that are blown with the same amperage rating.

4. Check Wheel Speed Sensors

Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel for easier access to the wheel speed sensors.
Inspect the sensors for dirt and damage; clean if necessary.
Reconnect any loose connectors and ensure they are secure.

5. Test ABS Module

Disconnect the ABS module electrical connector.
Using a multimeter, test for continuity and proper voltage at the module terminals as specified in the service manual.
If readings are outside specifications, consider replacement of the ABS module.

6. Refill Brake Fluid and Test

Check the brake fluid reservoir; top off with the manufacturer-recommended brake fluid if low.
Start the vehicle and test the brakes gently to see if the ABS light turns off after a few brake applications.
