| 3589 is a fault code saying that the difference in temperatures between the 2 EGT sensors is too great, causing the SCR system to shut down. More than likely one of the sensors is faulty. You will need an EST laptop to reset the system in addition to diagnose the system further as to which sensor is faulty(there are probably other codes not shown as well). And yes, update the software on the DNox unit and ECU(engine controller) if they don't have the newest software. Good luck!! | |
