SCO 001872.18 – Front Hitch Position Sensor, Voltage Too Low

SCO 001872.18 (SCO 1872.18)

Code: 001872.18

Shortcode: 1872.18

Description:

This error code, SCO 001872.18, indicates that the voltage of the front hitch position sensor has fallen below 0.3 volts. This low voltage suggests a potential short to ground or an open circuit, which can prevent the sensor from operating correctly.

Reaction:

When this fault is detected, the control software will have limited or no function of the front hitch.

Recommendations:

  • Inspect Wiring for Shorts:
    • Check the wiring and connections to the front hitch position sensor for any signs of shorts to ground or open circuits. Repair or replace any damaged wires.
  • Verify Power Supply:
    • Ensure that the power supply to the sensor is stable and within the required voltage range. Replace the power supply components if necessary.
  • Check Electrical Connections:
    • Inspect all electrical connections for corrosion, looseness, or damage. Clean and secure connections as needed.
  • Monitor Voltage:
    • Continuously monitor the voltage at the position sensor input to ensure it stays within the recommended range.

Note:

  • Preventive Maintenance:
    • Regular inspections of the electrical system can help identify and address potential shorts or open circuits before they cause operational problems.
