Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse.
Use a multimeter to test for continuity in the fuse.
If blown, replace the fuse with one of the same amperage rating.
Reconnect the battery and check if the ABS light remains off.

3. Inspect and Replace ABS Sensors

Remove the wheel to access the ABS sensor.
Disconnect the ABS sensor connector and inspect for corrosion or damage.
If necessary, remove the sensor using a socket set and replace it with a new sensor, ensuring proper alignment.
Reconnect the sensor and reinstall the wheel.

4. Brake Fluid Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top up with the manufacturer-recommended brake fluid type.
Inspect brake lines and calipers for leaks and repair as needed.

5. Test the ABS Control Module

If previous steps do not resolve the issue, the ABS control module may need testing.
Consult the service manual for specific testing procedures and torque specifications for any mounting bolts.
Replace the module if it fails tests or shows signs of damage.
