ACU 524212.02 – Rear Hitch Control Lever Conflict

ACU 524212.02 (ACU )

Code: 524212.02



This error code, ACU 524212.02, indicates a discrepancy between the rear hitch control lever switch position and the corresponding sensor voltage readings. This conflict suggests a problem with the switch or sensor, which may prevent accurate control of the hitch’s position.


In response to this detected conflict, the hitch system has been automatically disabled to prevent incorrect hitch operations and ensure safety.


  • Inspect the rear hitch control lever switch and sensor for any signs of physical damage or malfunction that might be causing the voltage conflict.
  • Test the voltage output at various positions of the control lever to ensure the sensor is accurately reflecting the switch’s settings. Use diagnostic tools to measure and record these voltage levels.
  • Check all wiring and connections related to the hitch control lever switch and sensor for any issues such as loose connections, corrosion, or damaged wires that could be impacting signal integrity.
  • Recalibrate or adjust the sensor and switch to align their outputs. Ensure both components are properly synchronized according to the manufacturer’s specifications.
  • If recalibration does not resolve the issue, consider replacing the faulty switch or sensor to restore proper function. Make sure any new components are correctly installed and integrated into the control system.


Maintaining synchronization between mechanical switches and electrical sensors is crucial for the accurate operation of hitch controls. Regular maintenance and diagnostics are recommended to detect and correct any discrepancies early, thus maintaining the reliability and efficiency of the machinery’s hitch system.
