This error code indicates that the supply voltage to the Instrument Unit (ELX) has exceeded 15.5 volts while the engine speed is above 500 RPM. This can occur due to issues with the alternator, voltage regulator, or wiring that leads to an overvoltage condition.

The error code ETC 600006.13 is triggered by the CommandCenter (DTI) when it receives an ETC diagnostic trouble code via the CAN BUS that is not stored in the DTI memory. This “general” diagnostic trouble code enables the CommandCenter to display information relating to this unknown ETC diagnostic trouble code.

The error code ETC 523979.05 is triggered when the control unit measures too low an amperage at the signal input of the indicator light in the rear window heater switch (S139, lead 2021). This indicates an interruption in the circuit or, on tractors without the optional “heated rear window”, an incorrect entry at input address…

The error code ETC 523848.07 is triggered when the control unit receives a valid position signal from the potentiometer of the air distribution adjusting motor (B132), but the motor cannot be moved to its desired position via the motor’s connecting leads. This indicates a mechanical fault at the air distribution or an open line at…

The error code ETC 523848.03 is triggered when the control unit measures a voltage in excess of 5 volts at the signal input of the potentiometer for the position of the air distribution flaps (adjusting motor B132 for air distribution, lead 2017). This indicates that the circuit is shorted to a supply lead or is…
