Solution

1. Preparation

Gather tools and parts.
Disconnect the vehicle's negative battery terminal to ensure safety.
Raise the vehicle and secure it with jack stands if necessary.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, torque wrench, cleaning solvent.
Remove the wheel and tire assembly to access the wheel speed sensors.
Disconnect the electrical connector from each wheel speed sensor.
Remove the sensor from the hub assembly.
Clean the sensor and mounting area to remove any debris or corrosion.
Reinstall the sensor and torque to manufacturer specifications.
Reconnect the electrical connector.

3. Check ABS Wiring Harness

Visually inspect the wiring harness for signs of wear, fraying, or disconnection at the ABS module and wheel speed sensors.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wires or connectors.

4. Inspect Brake Fluid and ABS Pump

Check the brake fluid level in the master cylinder; top off with the recommended brake fluid type if low.
Listen for the ABS pump activation during a brake application; it should make a noise indicating it is functioning.
If the ABS pump is non-functional, replace the pump assembly.

5. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear the C1441 code from the ABS module.
Conduct a test drive to ensure the ABS and traction control systems are functioning correctly.
