Strato_54 Posted August 5, 2019 Share Posted August 5, 2019 Since my 97 SE has an obd2 reader, i am curious as to what can be read from it. Some vehicles to my knowledge only show things such as engine codes and small things like that, while others can show stuff like water temp oil temp rpm and such with a more advanced scan tool. In my pathfinder, I want to make it more functional towards camping with my trailer and road tripping so I am wanting to put together a little tool i can use to read stuff about my car. My question is if i plug in an obd2 reader, what can i view from the computer other then the basics such as engine codes. Link to comment Share on other sites More sharing options...
dogla Posted August 5, 2019 Share Posted August 5, 2019 Is it an OBD2 port? Mine has Nissan Consult port and I have a '98Sent from my SM-G973U1 using Tapatalk Link to comment Share on other sites More sharing options...

CALPATHY Posted August 6, 2019 Share Posted August 6, 2019 There is an OBD hook up, bu no oil pressure or oil temperature (no sensor, for it, only for no oil pressure light) , but the other items you listed are there, plus a whole bunch more like maf airflow, etc. most of which I don't recall right now. 1 Link to comment Share on other sites More sharing options...
dogla Posted August 6, 2019 Share Posted August 6, 2019 All I have on my truck is this port.And the tool I have connected to it to read vitals is a consult diagnostic reader which is connected to a windows tablet I integrated in my dash as head unit.Sent from my SM-G973U1 using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my SM-G973U1 using Tapatalk Here in Canada it was standard for all vehicles made after 95 to have them so theres a chance your model didn't have to have that standard. Maybe i'm wrong but there should be one there. Its normally a white plug next to the hood release. Link to comment Share on other sites More sharing options...
dogla Posted August 6, 2019 Share Posted August 6, 2019 Probably because mine is a Japanese version it came only with a consult port and no obd-2 port....Sent from my SM-G973U1 using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my SM-G973U1 using Tapatalk Hey man, mine is the same. What information can you get with the consult diagnostic reader? Any live stuff while driving? I've used the metal pin method to diagnose engine fault codes but if we can get more live info using this tool I could be interested in getting one! 1 Link to comment Share on other sites More sharing options...
Strato_54 Posted August 6, 2019 Author Share Posted August 6, 2019 from my basic knowledge it reads the same thing as the obd2 but not as much info and nissan uses it for dealer scanning from what i know of. from what i know it does the same thing Link to comment Share on other sites More sharing options...
dogla Posted August 6, 2019 Share Posted August 6, 2019 I use a program called ECUtalk and get rpm, speed, injection timing, air flow and a lot more. Here's what I might use and there's still more gauges to select from. Also read fault codes.Sent from my SM-G973U1 using Tapatalk 1 Link to comment Share on other sites More sharing options...
onespiritbrain Posted August 6, 2019 Share Posted August 6, 2019 The FSM mentions using a consult for some pretty technical stuff in "data monitor mode" that is definitely not possible with OBDII. Link to comment Share on other sites More sharing options...
jtchal Posted August 6, 2019 Share Posted August 6, 2019 Nice. I didn't realise it could pick up so much info, I will definitely look into now, cheers! Hopefully it's ECUtalk is compatible with android phones. Link to comment Share on other sites More sharing options...
Sjackson2 Posted August 6, 2019 Share Posted August 6, 2019 If you use torque pro you can monitor airflow, coolant temp, o2 sensors, timing, maf, intake temp, speed, fuel trims, and a bunch of other stuff. Car gauge pro allows you to do the idle volume and self learning and adjust base timing 2 degrees plus or minus. You can do a ton of stuff 1 Link to comment Share on other sites More sharing options...

Mr_Reverse Posted August 6, 2019 Share Posted August 6, 2019 Nissan was a little weird with the data ports in the last 4 years of the 20th century. North America federal law required OBDII for the 96 and later model year light trucks and autos. OBDII was a standardized connector port and diagnostic code format. For the last half of the decade, manufacturers were required to have the basics for data and engine codes accessable through the standardized connector. Because it was an expensive and difficult change, manufacturers were given time to adapt and change to the new standard. Many, Nissan included, adapted by running the OBDII as an add-on. The results is that from 96 to 99, you can get the basics through the OBDII port, but if you want full data, you have to go through the Consult port. It was about 2000 when Nissan dropped the Consult port and finished the changeover. That said, even though there is a lot that is accessible through OBDII, there is even more that is still manufacturer specific that requires the proper software to access. OBDII is still and will most likely always be a minimum standard. There is simply too much money invested to make everything meet a standard. Oddly, Ford was an early adopter, with many of the 95's having OBDII, just not federally certified. All that said, all 1996 and newer Nissans that were for North American markets have the standard OBDII port under the left dash near the Consult port. Just don't expect much from them for data.

Im trying to make a live reading tool thats always plugged in and i was going to use an obd2 to usb and tunerstudio to do this but if i can get more i would love to know how. But again has to be for linux because of the hardware im using Link to comment Share on other sites More sharing options...
Mr_Reverse Posted August 6, 2019 Share Posted August 6, 2019 Only way to get full info from your 97 is to run Consult 2 software and be hooked up to the Consult port. Not that there is much there compared to what you get with stuff from the last 15 years. The electronic engine controls were still rather primitive. With the OBDII, you can get basic info like O2 sensor millivolts, MAF data and ECT data. Oil pressure, oil temp, and things like that just doesn't exist, there is no sensors for those and the ECU doesn't know to look for it. The 3.3 is basically a punched out 3.0 and was from a simple time. It wasn't until the VQ35 that the ECU started to control more than the basics and needed more information.

onespiritbrain Posted August 8, 2019 Share Posted August 8, 2019 (edited) if you are just wanting to monitor the running condition of the engine then all you need is a decent obdii dongle. i use bluedriver and my phone and havent needed anything further. now i would love to have a permanent dash mounted tablet with the info obdii provides split screened with spotify but its too much trouble for what little data is available. my wife's vehicle shows all kinds of stuff and would def be worth it. heres what bluedriver can live monitor: Fuel System Status (open loop / closed loop) Calculated Engine Load Engine Coolant Temperature Short Term Fuel Trim Bank 1 Long Term Fuel Trim Bank 1 Short Term Fuel Trim Bank 2 Long Term Fuel Trim Bank 2 O2 Bank 1-1 Sensor Voltage O2 Bank 1-2 Sensor Voltage O2 Bank 2-1 Sensor Voltage O2 Bank 2-2 Sensor Voltage Intake Manifold Absolute Pressure Engine RPM Vehicle Speed Timing Advance for #1 Cylinder Intake Air Temperature Mass Air Flow Rate Absolute Throttle Position It looks like a lot after typing all that but its missing a lot like fuel rail pressure, oil pressure, torque calcs, etc. i will say though that what is available goes a long long way when troubleshooting issues. and bluedriver lets you save logs of all the data you collected point by point which you can plug into an excel sheet to make a super detailed graph and as long as you were paying attention to the duration of the recording when an issue was present you can go back and see exactly what was being effected. unless of course you have strange spikes in your data that cannot be explained..

This is what im looking into and is why i started this thread in the first place. Link to comment Share on other sites More sharing options...
