Using aux input for obd2 diagnostic

Hi guys, I have been researching on this site, and have gotten a few plans, but I'm just not sure if it will work.

 

Will it be possible to connect an obd2 link (thinking HKS OB-LINK) with an android device, and use Torque app to display the information? 

Then run that through the aux input of the navigation system to come through the popup screen, as I would rather use it for diagnostics then something as basic as fuel economy.

 

I am looking for an end result like the picture attached (from an r35)

 

Thanks

Sure thing. Get the appropriate cable that will plug into your phone's USB to provide you with the respective composite video output and away you go. It won't look as clean and sharp as the real graphics you get from your system (or an R35) but it'll be functional. The trick will be to ensure that the phone itself will mirror the screen via the cable and not only work when you're playing videos, for example. I doubt that will be the case but it's still something you'll need to test. I know my Samsung Note4 works fine in this manner, using an MHL cable which has the USB connector for charging as well as the RCA outputs (eBay job).

Your big problem is that almost nothing will talk to the ODBII in our V35s. I am not sure anyone ever has gotten any meaningful data out of our hybrid Canbus/OBDII setup. Happy to be proven wrong though.

 

Getting the data/display into the factory screen is easy - the amp in the boot has an aux in (that I currently use for DTV).

Ahh thanks, i think ill grab a cheap android (all i need it to do is receive info and display the torque app), and use the composite video. Is there any examples of people doing this before?

Ah really? Damn, I think I heard of some and the OB-LINK 2 says its compatible but I'm honestly not too sure.

 

How does your DTV input work?

Yeah they all say they are compatible with G35s, but their wiring setup is somewhat different to our Jp V35s.

 

The DTV is just plugged into the AV in for the screen/amp setup in the boot.

On their website it said nissan v35 with the coupe chassis code. Some people on this website said they had it one theirs, shouldn't it be the same for all jap v35s?

Try and find proof of someone using one and getting all the OBD data to work with Torque.

 

Hundreds of people have tried hundreds of OBD devices (I tried a couple of different ones many years ago - none worked). If it were as easy as you say, EVERYONE would have one in their V35s.

That said, these HKS units do look good and are fairly recent maybe they will work?

But go ahead - buy all the bits, and if you can get it all to work I will applaud you and follow the exact same route :) Let us know how you go!

Thank you, ill keep digging and let you know how i go.

The only compatibility issue will be with the connector. Essentially, there are two global standards for OBD-II connectivity, though those standards aren't absolute for all and some manufacturer discretion is allowed beyond the basics.

However, it surprises me to hear that a manufacturer would alter their OBD-II connectivity between a USDM and JDM variant of their vehicles. It makes no sense, as that would suggest that my Consult III+ scan tool is made for a specific region, which they're not.

Grow some nuts, take a gamble and test the theory. Someone always has to be the guinea pig, no matter how well researched they are to minimise the loss! ;)

Torque may not work. I have hobdrive working in my M35 stagea. I just checked in the pre defined vehicle settings and it lists 2001 v35 skyline. You can download the demo version for free to check if it works. May or may not. I use a vlink elm adaptor thing plugged into the obd port and connect to it via wifi.

Which vlink adaptor do you use? Do you have a link to it?

 

also, do you have pics of your setup?

      R34 Skyline climate control unit transistor

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
