Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Wear safety gloves and goggles.

2. Scan for Error Codes

Use an OBD-II scanner to read ABS error codes.
Document any codes present for reference.

3. Inspect and Replace Fuses

Locate the fuse box and identify the ABS fuses.
Remove the fuses using a fuse puller and inspect for any damage.
Replace any blown fuses with new ones of the same amperage.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level and top off with the appropriate type of brake fluid (DOT 3 or DOT 4).
If the fluid is discolored, consider a brake fluid flush.

5. Inspect ABS Sensors

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the ABS sensor at each wheel hub.
Clean any dirt or debris from the sensors and the mounting area.
If damaged, replace the ABS sensor with a new one.

6. Test the ABS System

Reconnect the battery and start the vehicle.
Check if the ABS light is still illuminated after a short drive.
If the light remains on, further diagnosis of the ABS control module may be necessary.
