Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent electrical shocks.

2. Scan for Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Record any ABS-related trouble codes for reference.

3. Inspect and Replace ABS Components

A. Check ABS Fuse

Locate the fuse box, typically found under the dashboard or hood.
Remove the ABS fuse and inspect it for any signs of damage.
Replace the fuse if necessary with one of the same amperage.

B. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connectors and clean them.
Use a multimeter to test the sensor resistance; replace any faulty sensors.

C. Check Brake Fluid Level

Open the hood and locate the master cylinder.
Ensure the brake fluid is at the proper level; top up with manufacturer-approved fluid if low.
Check the brake fluid for contamination and replace if necessary.

D. Inspect Wiring and Connectors

Visually inspect the wiring harness for wear, fraying, or corrosion.
Clean any corroded connectors with electrical cleaner and ensure tight connections.

4. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to clear any fault codes.
Start the vehicle and monitor the ABS light status.
If the ABS light remains on, further diagnosis of the ABS module may be needed.
