Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect ABS Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Clean any debris or corrosion from the sensors and connectors.
Ensure the sensors are securely mounted and the wiring is intact.

3. Check ABS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

4. Brake Fluid Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with the manufacturer-recommended brake fluid if low.
Inspect for any visible leaks in brake lines or connections.

5. Test ABS Control Module

Reconnect the battery terminal.
Use an OBD-II scanner to clear any existing error codes.
Perform a road test to see if the ABS light remains off and the system operates correctly.
