2014 Nissan Altima J2534
VIN# 1N4AL3AP7EN220051 Current Cal. 31036-9HM0A
Hey everybody, long time lurker first time poster. Anyways, I have a transmission shop behind me that wants me to reprogram a TCM in a 2014 Altima. Apparently they rebuilt the CVT and changed the valvebody for a used one. I looked up the required part number under the Nissan parts website and the current cal. seems to be correct for the vehicle. Now, when I go to the reprogramming section on the Nissan site and enter the current cal. it gives me a new cal. of 31036-9HM3D
Would that calibration be viable to use? He doesn't really say why he wants this done he just says it needs to be. When I pulled the current cal. with a scan tool I didn't see any codes or anything pending. This would be my first Nissan and would like to gain more experience. Its seems like in my area this could potentially be profitable. I have NERS ready and a PassThru4 w/ windows 7 pro and my powermaxxxx.
Any insight or guidance would be greatly appreciated. Thanks
Let someone else more knowledgeable than me respond however I'll put in my 2 cents. If there is an updated calibration like it's showing you then yes by all means do the update. Nissan wants the TCM updated to the latest cal after the rebuild an valve body because they say the older calibrations were causing premature wear and damage to the CVT. Wether that's actually true or not I have no idea.
Ok that makes sense, just trying to confirm I did my research correctly with compatible part numbers. Also, when I did a search online I came across this thread: productforum.autorepairdata.com/forum/printthr… (not sure if I can post outside links, if not feel free to remove) they talk about a specific problem with those year Altimas and part numbers not programming…
Hello Jr Office Manager/CIO …. According to Nissan Support all 2012 and up is not available for independent shops to use Pass thru 3 or 4 devices, because Nissan has not release for third party use. You must tow to Dealer for re-programming. The cal. 31036-9HD3D is the same message we was receiving on a 2015 Altima we were working on
Hmm, should this be a SIR for Donny to look into?
Hi Michael, As stated by another person. This procedure cannot be done outside of a factory tool at the moment., The TSB for these vehicles is NTB12-103G . Any of the vehicles listed on that TSB cannot be programmed through pass-through. and for Infiniti the TSB is ITB13-055C .. All those models listed fall under the same criteria.
Wow, what a total let down! Thanks everybody for the information. I’ll be saving that TSB as well.
Look up tool hut usa on you tube . He just posted a video yesterday doing one a 2014 altima
I watched that video this morning, I do find it odd he did it relatively quick and easy. Hmmm
maybe talk to Tool Hut USA. And Keith Perkings at L1 diagnostics. He is like a Nissan expert. But I was pretty sure they supported all transmission programming now.
Hopefully I can get to the bottom of this, what’s the worst that can happen if I attempt it? Brick?
According to Nissan Support if you attempt you blow the PCM
Like I said reach out to those 2 people and see.
No... you can program or reprogram the TCM module on these vehicles.. The TCM is separate from the CVT unit, located in front of the battery.. the CVT has no module installed.. These CVT units or valve body replacements from the dealer come with a CD.. this CD has the shift characteristics of the specific valve body or CVT unit depending what was replaced. If a used CVT unit / Used valve body is…
31036-9HM3D is the updated calibration you need. You CAN do this with a j2534 device such as a Cardaq +2 or +3. Updating a TCM is no problem. The problem arises is when a blank TCM is installed. This has been resolved by Nissan and the blank files can now be requested on nissan-tech info.com I have updated plenty of these with no issues.
Thank you for your help. So i went ahead and did every thing i needed to do to the best of my knowledge. Downloaded file, extracted, put in correct folder, 13.5 battery voltage etc. but when i came to the final step with Tweddle i got this message and that stopped me from moving forward. I've registered with the Nissan tech info site and confirmed my device through the email. Not sure what else…
This should be the username and password of the person who has purchased and downloaded the NERS software.
Michael, you should read the bulletin. You performing the update is all fine well and good. But the valve body is used from another transmission. that valve body has a number stamped on it.. that number on the valve body is needed so the TCM knows how to shift using that specific valve body. The update you will be performing will not change the fact that the vehicle will not shift properly…
What Steven said is absolutely correct. I believe there is some miscommunication. Updating the TCM is one thing writing the shift data is another. You absolutely must have a Consult 3 plus for that. often times if used CVT‘s are sourced it is advised to also get the TCM from the donor vehicle.
Not to be a negative Nancy but unless the used valve body happens to be a updated one I would imagine he is going to end up with a permanent judder code
You might be better off getting a Nissan valve body with the cd, I have seen a lot of time wasted trying to get the calibration data for a used valve body. The valve body used to be what I would consider fairly expensive but recently they have come down in price
