This diagnostic trouble code, RPT 001890.03, is generated when the RPT control software registers a voltage in excess of 85% of the system voltage at the PTO shaft spline identifier switch. Such high voltage levels indicate a malfunction in the PTO shaft spline identifier switch or associated circuitry.

This diagnostic trouble code, RPT 001883.31, is generated when the RPT control software detects that the rear PTO speed is too high. If this diagnostic trouble code is generated despite being certain that the rear PTO speed is not actually too high, it indicates the need for an operational checkout of the rear PTO speed…

This diagnostic trouble code, RPT 001883.00, is generated when the RPT control software detects that the rear PTO speed is much too high. If this diagnostic trouble code is generated despite being certain that the rear PTO speed is not actually too high, it indicates a potential malfunction in the rear PTO speed sensor.

This diagnostic trouble code, RPT 001504.31, is triggered when the OIC control software detects an open circuit to the operator presence switch. 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 OIC control software, which takes priority over…

This diagnostic trouble code, RPT 001504.19, is generated when the OIC (Operator Information Center) control software cannot determine the presence of the operator and thus cannot provide the CAN bus with any relevant data. A transmitted replacement value generates this diagnostic trouble code in the RPT control software. When active, this fault also generates a…

This diagnostic trouble code, RPT 001504.09, is generated when there is a data transfer problem between the RPT control software and the OIC (Operator Information Center) 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 can indicate…

This diagnostic trouble code, RPT 000628.02, is generated when there is an error reading the internal module (EEPROM) of the control software. The EEPROM is responsible for storing essential data, and an error in reading it can lead to significant issues in the control software.

This diagnostic trouble code, RPT 000190.31, is triggered when the ECU control software detects an open circuit to the engine speed 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 ECU control software, which takes priority over…

This diagnostic trouble code, RPT 000190.19, is generated when the ECU control software cannot determine the engine speed 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 also generates a diagnostic trouble…

This diagnostic trouble code, RPT 000190.09, is generated when there is a data transfer problem between the RPT control software and the ECU (Engine Control Unit) 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 can indicate…
