Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Wheel Speed Sensors

Tools Required: Socket set, multimeter, wrench set
Locate each wheel speed sensor and visually inspect for any physical damage or disconnection.
If damaged, replace the wheel speed sensor:
- Remove the sensor mounting bolt(s).
- Disconnect the electrical connector.
- Install the new sensor and reconnect the electrical connector.
- Torque the mounting bolt(s) to the manufacturer's specifications.

3. Check and Repair Wiring

Inspect the wiring harness leading to the ABS module and wheel speed sensors.
Look for frayed wires, corrosion, or broken connectors.
Repair any damaged wiring by splicing in new wire of the same gauge and sealing with heat shrink tubing.

4. Test ABS Module

After repairs, reconnect the battery.
Use an OBD-II scanner to clear the C1441 code.
Start the vehicle and perform a test drive to check if the ABS warning light remains off.

5. Final Inspection

Recheck the brake fluid level and ensure no leaks are present.
Conduct a visual inspection of the brake components and ABS module.
