Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery cable to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the ABS fuse in the fuse box (refer to the owner's manual for the exact location).
Use a multimeter to test the fuse for continuity. Replace if blown.
Reconnect the battery and check if the ABS light is still illuminated.

3. Inspect and Clean ABS Wheel Speed Sensors

Raise the vehicle and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean the sensors and the sensor mounting area to remove any dirt or debris.
Reconnect any disconnected wires and ensure they are secure.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module.
Check for any frayed wires or corrosion at connectors. Repair or replace damaged wires as necessary.
Ensure all connectors are seated properly.

5. Test and Reset ABS Module

If error codes were stored, clear them using the OBD-II scanner.
Perform a self-diagnostic check on the ABS system using the scanner.
If the ABS light does not reset, the ABS module may need to be replaced.
