Are there different ABS module coding/firmware between 2row and 3row?

Is there? Specifically - T32 generation.
COuldn't find anything in FSM, a while ago tried to talk to dealership techs - no joy.

Nissan doesn't specify that, the technician just gets a VIN-specific program number (ROM-ID) from the parts catalog and programs the new unit accordingly. The only way to find out if the programs differ would be to get the ROM-ID's for a 2-row VIN and a 3-row VIN from the same model year, and even that might not give you the desired result. The ABS participates in ADAS and VDC functions involving other devices, so the ROM-ID's will probably vary depending on what specific devices the ABS needs to converse with.

PS - ROM-ID's are usually searchable at NissanPartsDeal.com, so if you're looking at a used ABS, get the VIN from the donor vehicle. If the donor ROM-ID matches the ID for your ride, then it fits.

PPS - None of this applies to the T33's. The T33 programs are directly downloaded from Nissan's servers at the time of programming, so the technician doesn't even know the software part number until after programming.

thanks! something to investigate... again and again

so... I found according to cars specs ecu - https://www.nissanpartsdeal.com/parts/n ... 4ba1a.html
it says blank
that 4BA1A is supposed to be ROM-ID, or ROM_ID I can read only via software(like def files here - https://github.com/Pytrex/NissanDefinit ... ons/Altima )?(I think Autel AP200 showed some kind of id, but I have misplaced it somewhere... will try a bit later with CarScanner and EconTool.)

Yah, practically all of Nissan's new C/U's come blank these days. What your Autel is uploading is probably the software part number, but that won't match the ROM-ID. The ID is an index that points to the right program in the database, much like the 22611N in that parts diagram points to ECM p/n 23703-4BA1A. The index doesn't mean much by itself, except to say that VIN's with identical ROM-ID's for a given part will use identical firmware for that part.
