Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve ABS-related error codes.
Note any codes for reference during repairs.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor (usually mounted on the wheel hub).
Clean any dirt or debris from the sensors and their connectors.
Check for physical damage or corrosion and replace if necessary.

4. Check ABS Fuse

Locate the fuse box (refer to the owner’s manual for location).
Remove the ABS fuse and check it for continuity using a multimeter.
Replace any blown fuses with the correct amperage.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors for the ABS system.
Repair or replace any damaged wiring or connectors.

6. Brake Fluid Level Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with the manufacturer's recommended brake fluid type if low.

7. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Perform a short test drive to ensure the ABS light does not reappear.
