Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuses

Locate the fuse box and identify the ABS fuse.
Use a multimeter to check the continuity of the ABS fuse.
If the fuse is blown, replace it with a new one of the same amperage.

3. Brake Fluid Inspection

Remove the master cylinder cap and check the brake fluid level.
If the fluid is low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack, and secure it with jack stands.
Locate and visually inspect each ABS wheel speed sensor for damage or dirt.
Clean the sensor connectors and harnesses with electrical contact cleaner.
If a sensor is damaged, replace it with an OEM part.

5. Test the ABS Control Module

Reconnect the battery and use the OBD-II scanner to clear any stored codes.
Perform a test drive to see if the ABS light returns.
If the light reappears, further diagnostic testing of the ABS control module may be needed, which could require professional service.
