Solution

1. Preparation

Gather tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Check and Replace Fuses

Locate the fuse box and identify the ABS fuse.
Use a fuse puller to remove the ABS fuse.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Inspect and Clean ABS Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor wiring harness.
Remove the sensors using a socket set.
Clean the sensor tip and surrounding area with brake cleaner.
Reinstall the sensors and reconnect the wiring harness.

4. Inspect Wiring and Connectors

Visually inspect wiring harness and connectors leading to the ABS module for fraying or corrosion.
Use a multimeter to check for continuity in the wiring.
Repair or replace any damaged wiring or connectors.

5. Brake Fluid Check

Locate the brake fluid reservoir under the hood.
Check the fluid level and top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
If the fluid is dark or contaminated, perform a brake fluid flush.

6. Reset ABS Light

Reconnect the vehicle battery.
Use the OBD-II scanner to clear the ABS fault codes.
Perform a test drive to ensure the ABS light does not re-illuminate.
