T32, MY2014, QR25DE, with intelligent key - instrument cluster identification

[V6er]

Yello!

as usually when I have too much free time - I come to FUNtastic ideas
like - let's get another instrument cluster and see what can (am able to) do with it. especially since there are people who have managed to use them outside the car - https://www.youtube.com/watch?v=UTwVOWjcMog , for example. but my interest is more to "get inside cluster" and do some things that were not really planned by nissan.

did a little search on ebay. there are a bunch of those for 30bucks. sounds nice.
but there is an issue: part numbers.
1) I started with nissanpartsdeal.com - it lists different part numbers for different production times. according to sticker in drivers door opening - our is 11/13.
though fun part is that nissanpartsdeal.com data starts at december of 13
24810-4BA0B - Production Date: 12/2013-03/2014 - Replaced by: 24810-4BA8A - https://www.nissanpartsdeal.com/parts/n ... 4ba0b.html
24810-9TA0A - Production Date: 04/2014-09/2014 - Replaced by: 24810-9TA8A - https://www.nissanpartsdeal.com/parts/n ... 9ta0a.html
24810-4BA3A - Production Date: 09/2014-06/2016 - Replaced by: 24810-4BA8A - https://www.nissanpartsdeal.com/parts/n ... 4ba3a.html

so, I guess - this is why our Rogue is at 216kmiles and still kickin' - because it was preproduction sample done by engineers themselves?

2) on ebay - most of "part numbers" seem to be not really part numbers.

seems like that is the sticker on back of instrument panel with calibration software version?


and few more questions:
1) is it possible to program instrument cluster so that it can be switched back and forth with two, so I can "play" with their internals, but still have working car?
2) are there real known differences between clusters?
3) from the pictures on a back of instrument clusters - I see there are testpads there. is there any information on those? what signals are there, etc
4) connectors for wiring. https://prnt.sc/bdnYEjfokZth - this is picture from FSM. anybody has suggestions what are connector specs/names to get them? can they be found in parts catalog by nissan? https://static.nhtsa.gov/odi/tsbs/2020/ ... 5-0001.pdf - looks like not really viable to try to get something from nissan itself

40pin connector probably is Toyotas 90980-12169, 90980-12170 ...

[VStar650CL]

The connector is a Sumitomo NH series, TH40FW-NH. Nissan uses that type all over the place, including practically all their late model clusters. That makes them very easy to find in junkyards, BUT (important but), they're hellish to unpin and different models can have completely different schemes for the wire locations. You can get fully-loaded pigtails for $17 here:
https://www.aliexpress.us/item/3256806832656328.html
Tariff is covered by the vendor and shipping is pretty prompt, usually under 10 days.

Differences between the clusters on a '14 will be in the warning lamps and the firmware driving them, depending on the car's equipment list. Nissan clusters before about '21 weren't CAN-reprogrammable, so you'd need an application-specific programmer and firmware from the manufacturer to make use of the programming ports on the circuit board. The needed programmer may or may not be available to the public, but the firmware certainly won't be. The exposed port on the back is probably for manipulating the EEP or flash that stores the odo and other parameters which are configurable. Chances are there's another one inside which is used for firmware.

maaaaan! )) THANK you!
do you happen to have part number for that other connector - 12pin - too?

[VStar650CL]

It's the same family, TH12FW-NH. You can get that one from Nissan, p/n 24008-9DM6B, but it isn't cheap. It's also used all over the car, shifter, roof console, EPB, IPDM, spiral cable. So that one is really easy to find in JY's.

[V6er]

holly molly - 60bucks and that is online store... thanks!

[VStar650CL]

Oh, hey... it just occurred to me that they use that same 12-pin in the standard accessory connector, 999Q9-AY000. Those are $15~20 all over the place and they're fully stuffed.

[V6er]

I will try to find TH12FW-NH first. because I realized that I _might_ need to do something along lines of "man-in-the-middle" "attack" .
and looking at wiring diagram - this 12pin connector is the one carrying both can busses...

that seller you gave link to - he had lovely sets of female-male connectors, but he doesn't have this TH12FW...
though seems like toyota part numbers might be used...
what do you, @VStar650CL, think about this - https://www.aliexpress.us/item/3256806960036965.html ? seems legit

[VStar650CL]

I wouldn't bother with China on that. With the shipping it's $10, and you can get a clone accessory pigtail here in the 'States for the same $10.

yeah - it is cheap! ) but now I want male and female connectors - to be able to insert can-bridge between instrument cluster and other devices (to help me with hacking/logging )

soo... how is your crystal ball? does this seem to be the right connector? https://www.aliexpress.us/item/3256806960036965.html

oh, and what about ability to program instrument clusters to work with NATS? I recently asked you about ECU, but those are not going to work...

[VStar650CL]

That's definitely the right connector for a M/F setup, yes. NATS is irrelevant, the cluster isn't a participant. On a gen2 the only NATS/NVIS participants are the BCM and ECM. There's no discrete IMMU (it's a dumb antenna) and the IPDM is a spectator. The only part the cluster plays is turning the red key icon on and off at the BCM's direction. The actual cluster firmware and the non-volatile parameters like the odometer won't be alterable via CAN (although you may be able to rewrite RAM parameters like the DTE and trip odos).

[V6er]

thanks again!

what I would like to achieve - are many things... it boils down to ability to edit firmware adding/removing/changing stuff. but how far will I get - I don't know...

[VStar650CL]

You won't get anyplace with the CANbus. If you can identify the master chip on the circuit board, you might be able to get a programmer for it and decompile the program (assuming it isn't code-protected). If it's an ASIC then that's probably wishful thinking, but if it's a commercially-available microcontroller then maybe.

[V6er]

you always know how to get hopes up... and down.......

[VStar650CL]

Sorry. Just don't shoot the messenger.
