ACU 524101.02 – Front Hitch Control Lever Conflict

ACU 524101.02 (ACU )

Code: 524101.02



This error code, ACU 524101.02, indicates a conflict between the front hitch control lever switch and the corresponding sensor voltage. This discrepancy suggests an issue with either the switch’s physical condition or the sensor’s electrical output, resulting in conflicting data being sent to the control system.


To prevent improper hitch operation which could lead to unsafe conditions, the hitch system is automatically disabled when this conflict is detected.


  • Inspect the front hitch control lever switch for any physical damage or wear that might affect its function. Ensure that the switch operates smoothly and correctly reflects the lever’s position.
  • Measure the voltage output from the sensor associated with the front hitch control lever to confirm that it matches the expected values for given positions of the lever. Any discrepancy in voltage could indicate sensor malfunction or wiring issues.
  • Check all related wiring and electrical connections for signs of damage, corrosion, or loose connections that could affect signal integrity between the switch and the sensor.
  • Recalibrate both the switch and the sensor to ensure they are properly aligned and providing accurate data to the control system.
  • If recalibration does not resolve the conflict, consider replacing the faulty switch or sensor to restore proper functionality to the hitch system.


Regular checks and maintenance of both mechanical and electrical components of the hitch control system are crucial to ensure safe and reliable operation. Accurate communication between the control lever, switches, and sensors is essential to maintain control and prevent equipment failure.
