John Deere AdBlue system faults
Due to AdBlue faults present on this machine, it was no longer possible to move it. Indeed, the fault code SPN 189 FMI 31 as well as the fault code SPN 4364 create a degraded mode with a restriction of the power and the engine torque.
Fault 4364 at John Deere indicates a fault in the operation of the AdBlue system, more specifically at the level of the SCR catalytic conversion.
Code SPN 189 31 meanwhile indicates that a parameter requires restriction of torque and motor power. Finally, code 1569 FMI 31 tells him that degraded mode is active.
How to reprogram a John Deere harvester to remove AdBlue permanently?
John Deere 1270G harvesters operating under the third-party 4F emission standard are controlled by an L33 engine management module. The L33 computer therefore manages the engine operation of this harvester fitted with the 9-litre John Deere Phoenix 6090HTJ28 engine. This engine management module also manages the entire exhaust gas post-treatment system and reprogramming this computer will therefore eliminate the use of AdBlue on this vehicle.
Definitive deletion of the fault code deletion of the power limitation
After having reprogrammed the engine management computer as well as all the parameters relating to the AdBlue system, there will no longer be any fault on the vehicle and it will regain its full power and torque for good.
In some cases, the system message def may indicate a fault, but this is not the case, it depends on the software version and the possibility of passing this message. The machine will continue to work well without any limitations.
