    Exclamation ECU A 652.03 Fault Code on 3046R

    Has anyone had a "ECU A 652.03" Fault Code on their 3046R?

    I've had this happen twice now. First time, I shut it off and the fault went away after restarting. Second time, 50 hrs later (today) it did it again. I shut it off again but the fault code did not clear (it also reduced power dramatically and almost sounded like the engine was missing)? I pulled it in the garage and washed it all up after mowing my lawn, now (60 minutes later) I have no faults and my 3046R operates normal....

    Any help or recommendations are greatly appreciated!

    Download the John Deere TractorPlus app for your phone. Overall it’s not a very useful app, but it does have an Error Code lookup.

    652.03 ECU Fuel injector circuit fault. See your John Deere Dealership.

    Hope it helps.

    Very helpful, I downloaded the app.

    I hate to go to dealership if the fault is not active.... I suspect this is not a warranty covered item on my three year old tractor??

    Thanks again.

    Your powertrain should have a 5 or 6 year warranty (I think that started quite a few years ago) - It just gets sticky when they define which parts are under that warranty and if it affects emissions or DPF - then it would most likely be covered.

    Question "Injector #3 Circuit Out Of Range High" ??

    ECU Code 652.03 in my service manual shows: "Injector #3 Circuit Out Of Range High"

    Can one of you very knowledgeable folks (or a Certified Deere Mechanic) please tell me exactly what that means?

    There are many 3046R owners on here, surely someone else has had this same issue happen and can share their experience?

    Again, this issue has only happened twice and the code has cleared both times after sitting (glad I took a photo of the code on the dash)....very hard to diagnosis an intermittent issue. I would bring it to the dealership if the injector had failed or the code remained on, but that is not the case. Should I continue to operate it and wait for it to fail completely?

    Any advise and or your recommendations are greatly appreciated.

    Question New Code ECU 652.05 Injector #3 Circuit Has High Resistance

    Went from an ECU Code 652.03 "Injector #3 Circuit Out Of Range High" to this new code ECU 652.05 "Injector #3 Circuit Has High Resistance" so now it is off to the dealership on Monday and hopefully the diagnostic codes are still active when I drop it off! I checked all injector wires and put some dielectric grease on the electrical connections, still showing the code and missing (only running on two cylinders).


    Any other suggestions before I take her in are appreciated??

    My dealer found a loose pin in the main ecu harness connector to the circuit for the #3 Injector. All is well again!
