2. Diagnose and Replace Wheel Speed Sensors (if faulty)

Tools Required: OBD-II scanner, multimeter, socket set
Inspect each wheel speed sensor's connector and wiring for damage.
If a sensor is faulty, remove the wheel and brake components as necessary to access the sensor.
Unplug the defective wheel speed sensor and remove it using the appropriate socket size.
Install the new wheel speed sensor and reconnect the wiring.
Reinstall the brake components and wheel.

3. Repair or Replace ABS Module (if needed)

Tools Required: Socket set, torque wrench, brake fluid
Access the ABS module, usually located near the master cylinder.
Unplug the ABS module wiring harness and remove the mounting bolts.
Inspect for corrosion or damage; replace if necessary.
Install the new ABS module and reconnect the wiring harness.
Torque bolts to manufacturer specifications.
