Valve body reprogramming procedure required

Shop Replaced Valve Body

Hi all, first time around with a Nissan CVT. TSB NTB15-037f states that programming is required for this model when valve body is replaced. I am just wondering about how you choose the file for the TCM. I am using NERS and will do the other adaptations with an aftermarket tool.

The bulletin states to "erase calibration data " with the C3 then program. I have both iScan & Gscan and they both list erase calibration data. So would I erase the data, switch to NERS, then program , then switch back and erase memory data, reset the fluid life, then perform clutch point learning?

Nissan is one of the few OE tools I don't have as I haven't been able to justify it as I see so few.

But now, if you can use any laptop, not just the specced Toughbook, I probably will get it. Then they will change over to something else.

Thanks in advance.

Should I pull the existing part # from the TCM, and grab the superceding file from Nissan's site?

Ners is very confusing. You should google Nissan Ners programming. There’s a pretty good video that walks you through the process. You don’t need a special laptop to put Ners on it. What type of J2534 do you have? If it’s a Cardaq they will help you. If think you’re going to do a lot of Nissan programming then do it. If not get a mobile guy to do it. It’s much easier!

I am a mobile guy. Just one who stayed away from Nissan. I have done a few ECM's on these and that is for the most part easy. Part of the reason I have steered away from these is because of the lack of good systems training, the fact that up until recently you had to purchase a particular CF19 Toughbook for C3 and the fortune cookie Engrish that their TSB's & service info is written in.

I realize you do not have to have a special laptop for NERS, I was just stating that until recently you had to have one for C3+

I obtained this based on what the dealer offered as a part # So, do I erase calibration data, then program the TCM with this file using NERS, then perform the other adaptations?

All you need to do is load that software in to the control module then reset calibrations fluid percentage and perform quick learn cvt super simple any j box works i use cardaq or pass through pro. just need to get the first one out of the way I've done dozens

That looks like the engine update you need to get the cvt control unit part number and put it in the same way

Thanks for the response. I really would like it if someone could decipher that TSB for me. I am especially puzzled by the clear calibration data part of the document.

Todd you program it first. The erase calibration data is done with scan tool after programming. It just erases the old stored values. Think of it as adaptation on a GM or JLR auto trans. Or CVI's on FCA. If you go into cal data before you erase you will see the learned values. Then after you erase you will see 0 for the various values. Then you can run the cal procedure and the TCM will learn…

Hi Caleb. I suspected it to be something like that. But if you look at the TSB, it tells you to clear calibration data first, then compare the TCM part #'s with C3+, I think.

Hmmm......yea those TSB's can be confusing for sure. I think you'll be fine either way. Its not going too hurt anything too clear them before so might as well. Lets put it this way. You are not going too brick something because you did or didnt clear the values at a certain time.
