Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes related to the ABS system for reference.

3. Inspect Wheel Speed Sensors

Raise the vehicle and remove the wheels to access the wheel speed sensors.
Visually inspect each sensor for damage, cracks, or debris.
Use a multimeter to test the sensor's resistance; replace if readings are outside of manufacturer specifications.

4. Check ABS Control Module

Locate the ABS control module and inspect for loose or damaged connectors.
Visually check the module for signs of corrosion or physical damage.
Reconnect any loose connections and ensure the module is securely mounted.

5. Test Brake Fluid

Remove the brake fluid reservoir cap and check the fluid level; top up if necessary with the correct type of brake fluid as specified in the owner's manual.
Inspect the brake fluid for contamination; replace if dirty or discolored.

6. Clear Diagnostic Codes
