Volvo I-shift : Neutral Secured Is Not Detected

I went out to start my truck this morning, the batteries were dead. It whirled over 3 slow painful times. I connected my Noco Boost jump box to it, and it wouldn't do anything. Looked at the dash and the message was there "Neutral Secured is Not Detected". I figured maybe it's cause the batteries were so dead there was not enough power for the ECU, ECM, TCM, etc. I went and got new batteries after having the other batteries tested. Put new batteries on and it still shows this message with no change at all. There was no battery power connected to the truck for about 40 minutes when I went and got the old ones tested and new batteries to put on. I did check the fuses, and though they weren't blown replaced them anyway and still didn't change anything either.

Any ideas? One place I called said its because there is no air in the system. Seems unlikely, as there's been many times before the truck has had no air in the tanks and this didn't happen. Another place said the gear selector (beside the driver seat on my truck) is bad and need to replace it. I can move the gear selector to D, R, M, and it shows on the dash in the "gear box" that it is in that gear, but right beside it shows "N1" signifying it is still in neutral.

I live in an area where none of the road service or fleet repair folks even do anything with Ishift transmissions so if I can't figure it out to get it started and moving will have to just fork up some tow money to a shop.

Thanks in advance.

 

I'll check the fuses again tomorrow. I replaced them all, every one I found that showed on the diagram to be for the transmission. Not sure how it would have gone into gear on its own though. Trippy.

 

Hey there sir, sorry for the late reply. Its a 2013 Volvo VNL 780. I had a guy from the shop a mile away from me come by. He was able to jump the starter, it started and ran for 3 seconds and shut off. He couldn't clear the codes then on the transmission. I think they are planning on coming with a farm tractor to pull it down to their shop. They will have to put air in the system somehow to release the brakes because I am sure they don't want to pull it with no brakes. Maybe then it will reset and start at least to get it there for them to find the issue. It's lost air pressure over night anytime I have shut it off, but never done this. He even disconnected some plug on the back top side of the transmission to try to see if it would reset and it didn't. He tested every fuse in the fuse panel with a test light and all tested good.

 

Well, I will wait and see what they intend to do. I am sure they will probably drop the shaft, just like a tow truck would. If not, I doubt one mile is going to destroy it. It may be destroyed already.

 

Well, the shop came back and put air in the tanks and it fired right up. All the codes it had (there was a lot of transmission failure, etc.) they all went away while driving the one mile drive to their shop. Still going to have them look at it. Hopefully they will find and repair whatever air leaks there are so this doesn't happen again. First time its happened, not sure if its just never been that low on air or what. Definitely don't want to have to deal with this every time it looses air pressure.
