HCC 001881.13 – HCC Calibration Fault/Rear Hitch Draft Sensor Circuit

HCC 001881.13 (HCC 1881.13)

Code: 001881.13

Shortcode: 1881.13


This error code indicates that the Rear Hitch Draft Sensor requires calibration. It occurs when the draft sensor voltage without load is out of the specified range (1.90—2.40 V). Failure to calibrate or an unsuccessful calibration can cause this code to be stored.


The HCC function is degraded when this error code is active.


  • Perform Calibration:
    • Calibrate the Rear Hitch Draft Sensor following the manufacturer’s instructions.
  • Verify Sensor Voltage:
    • Ensure the sensor voltage without load is within the range of 1.90—2.40 volts.
  • Inspect Wiring and Connections:
    • Check the wiring and connections to the Rear Hitch Draft Sensor for any damage, loose connections, or corrosion.
  • Recalibrate if Necessary:
    • If an initial calibration attempt fails, repeat the calibration process to ensure it is successful.
  • Replace Faulty Components:
    • Replace any faulty sensors or wiring components as needed.
  • Consult Technical Support:
    • If the issue persists after recalibration, contact technical support for further diagnostics and troubleshooting.


Accurate calibration of the Rear Hitch Draft Sensor is essential for proper operation. Regularly check and calibrate the sensor to maintain optimal performance.
