This diagnostic trouble code, RPT 000186.05, is generated when the RPT control software detects that the voltage at the output to the rear PTO speed sensor is too high, indicating an open circuit. An open circuit means that there is a break or disconnection in the electrical pathway, preventing the sensor from functioning correctly.

This diagnostic trouble code, RPT 000186.01, is generated when the rear PTO does not start up correctly after being turned on. The rear PTO is turned off and can only be turned back on again after 30 seconds. This indicates that the rear PTO is overloaded, possibly due to an implement being blocked or sluggish,…

This diagnostic trouble code, RPT 000177.31, is triggered when the PTA or CCU control software detects an open circuit to the transmission oil temperature sensor. A transmitted replacement value generates this diagnostic trouble code in the RPT control software. When active, this fault also generates a diagnostic trouble code in the PTA or CCU control…

This diagnostic trouble code, RPT 000177.19, is generated when the PTA or CCU control software cannot determine the temperature of the transmission oil and, therefore, cannot provide the CAN bus with any relevant data. This results in a transmitted replacement value, triggering the diagnostic trouble code in the RPT control software. When active, this fault…

This diagnostic trouble code, RPT 000177.09, is generated when there is a data transfer problem between the RPT control software and the PTA or PTD control software. The issue arises when the RPT control software intermittently or completely fails to receive one, several, or all of the expected CAN messages. This problem is indicative of…
