Remove the ABS fuse using a fuse puller.
Check the fuse for continuity with a multimeter; replace with the same amperage if blown.

3. Check Brake Fluid Level

Locate the brake fluid reservoir.
Remove the cap and visually inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid.

4. Inspect Wheel Speed Sensors

Jack up the vehicle and remove the wheel corresponding to the ABS light.
Locate the ABS wheel speed sensor and inspect it for damage or disconnection.
Clean any debris from the sensor area and ensure the connector is secure.

5. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to perform a system check on the ABS module.
Follow the scanner prompts to perform any necessary tests or calibrations.
