AIC 176865.02 – Rear PTO Remote Control Switch Malfunction

AIC 176865.02 (AIC )

Code: 176865.02



This error code, AIC 176865.02, is triggered when the control software is unable to determine the values of the remote control switch for the rear Power Take-Off (PTO). Consequently, it cannot provide accurate data to the CAN Bus, leading to the transmission of a replacement value which in turn generates this diagnostic trouble code. Note that RPT (Remote Power Train) and OIC (Operator Interface Control) diagnostic trouble codes will take precedence over this issue.


Due to this malfunction, the rear PTO’s functionality is either limited or completely disabled to prevent operational errors and ensure safety.


  • Inspect the remote control switch for the rear PTO to check for any physical damage, corrosion, or connectivity issues that might be impairing its function.
  • Test the switch with diagnostic tools to verify signal integrity and ensure it is transmitting clear and correct values to the control software.
  • Check the wiring and connections between the switch and the control unit for faults or signs of wear that could disrupt communication.
  • If the switch is faulty, replace it with a new one that meets manufacturer specifications, and then recalibrate the system to ensure proper communication with the CAN Bus.
  • Once repairs or replacements are completed, perform a comprehensive system check to ensure that the rear PTO is functioning as intended and that the error code does not reappear


Ensuring that all remote control switches and related components function correctly is critical for the seamless operation of PTO systems. Regular maintenance and swift resolution of issues like these are essential to minimize downtime and maintain operational efficiency in agricultural machinery.
