SCO 001872.04 – Front Hitch Position Sensor, Voltage Too Low

SCO 001872.04 (SCO 1872.04)

Code: 001872.04

Shortcode: 1872.04

Description:

This error code, SCO 001872.04, indicates that the 5-volt supply voltage to the front hitch position sensor has fallen below 4.55 volts. This condition suggests a potential short to ground, 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. 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 before they cause operational issues.
