Solution

1. Preparation

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

2. Inspect and Repair Wiring

Sub-steps:
- Remove the wheel covers and inspect the wiring harness for the ABS sensors.
- Repair or replace any damaged wiring or connectors.
- Reconnect the wiring ensuring a secure connection.

3. Replace Faulty Sensors

Sub-steps:
- If any sensors are damaged, remove the wheel and brake assembly as necessary to access the ABS sensor.
- Unscrew and remove the faulty ABS sensor.
- Install the new ABS sensor and torque to manufacturer's specifications (typically around 7-10 ft-lbs).
- Reassemble the wheel and brake assembly.

4. Check and Refill Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Inspect the fluid level. If low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
- Check for any leaks in the brake lines or around the master cylinder.

5. Clear Codes and Test Drive

Sub-steps:
- Reconnect the battery.
- Use the OBD-II scanner to clear the C-codes from the system.
- Start the vehicle and conduct a test drive to ensure that the codes do not return.
