John Deere fault codes

  • RPT 001890.03 – PTO Shaft Spline Identifier Switch, Voltage Too High

    John Deere error

    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.

  • RPT 001883.31 – Rear PTO Speed Too High

    John Deere error

    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…

  • RPT 001883.00 – Rear PTO Speed Much Too High

    John Deere error

    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.

  • RPT 001504.31 – Operator Presence Switch, Open Circuit

    John Deere error

    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…

  • RPT 001504.19 – Operator Presence Switch, Malfunction

    John Deere error

    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…

  • RPT 001504.09 – CAN Bus Message Cannot be Received, Information from OIC Control Software

    John Deere error

    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…

  • RPT 000630.13 – Control Software Not or Incorrectly Calibrated

    John Deere error

    This diagnostic trouble code, RPT 000630.13, is generated when the rear PTO is not calibrated or is incorrectly calibrated. Proper calibration is essential for the accurate operation of the rear PTO and the overall performance of the equipment.

  • RPT 000628.02 – Control Software Internal Fault

    John Deere error

    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.

  • RPT 000190.31 – Engine Speed Sensor, Malfunction

    John Deere error

    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…

  • RPT 000190.19 – Engine Speed Sensor, Fault

    John Deere error

    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…

  • RPT 000190.09 – CAN Bus Message Cannot be Received, Information from ECU Control Software

    John Deere error

    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…
