Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical work.

2. Inspect ABS Fuses

Locate the fuse box (refer to the owner's manual for exact location).
Remove the cover and check the ABS fuses for continuity using a multimeter.
Replace any blown fuses with new ones of the same amperage.

3. Check Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connectors and inspect for corrosion or damage.
Clean the sensor area and reconnect the sensors.
If damaged, replace the faulty wheel speed sensor.

4. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level and top off with manufacturer-recommended brake fluid if low.
Inspect the fluid for contamination; if contaminated, flush the brake system.

5. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to clear any stored codes.
Start the vehicle and perform a test drive to check if the ABS light remains off.
If the light returns, the ABS module may need replacement.
