Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts during repair.

2. Check and Replace ABS Fuse

Locate the fuse box (typically under the dashboard or hood).
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse; if damaged, replace it with one of the same amperage.
Reinsert the fuse and reconnect the battery terminal.

3. Inspect and Clean ABS Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Clean any dirt or debris around the sensors using a soft brush or cloth.
Ensure the sensor connectors are securely fastened and free of corrosion. Repair or replace any damaged connectors.

4. Brake Fluid Check

Locate the brake fluid reservoir and check the fluid level.
If low, add the recommended type of brake fluid (consult the owner's manual for the correct type).
If the fluid is contaminated (dark or murky), consider flushing the brake system.

5. Test Drive and Recheck ABS Light

Start the vehicle and allow it to idle for a few minutes.
Take the vehicle for a test drive, ensuring to perform hard braking in a safe location to assess ABS function.
After the drive, check if the ABS light remains off.
