Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for damage; replace it if blown.

B. Wheel Speed Sensors

Jack up the vehicle and remove the wheels for better access.
Locate the wheel speed sensors mounted near the brake assembly.
Disconnect the sensor connectors and inspect for dirt or corrosion.
Clean or replace any damaged sensors.

4. Check ABS Module Connections

Locate the ABS module, typically near the master cylinder.
Inspect wiring and connectors for signs of damage or corrosion.
Reconnect any loose or corroded connections securely.
