OBDII on a 95?

So can you not use an OBDII scanner to get codes off a 95? I am reading a bunch of adds for them and it seems as if 96 is the first year you can use this on.

This question comes up over and over again - i.e. where 95 Maxima's OBD-II compliant. I think OBD-II compliance was mandated for ALL manufacturers/models from 96-onwards. That doesn't mean that manufacturers didn't support it in 95. If you can pull codes at Autozone from your Max using their code reader, then you are OBD-II compliant.

I think this is answered in detail in the FAQ sticky... i.e. whether or not the 95s were OBD-II compliant. IIRC, they are.

I have the Auto Enginuity scan tool and used it on my 95'Max to diagnose a faulty Bank 2 O2 sensor so in answer to your question, it is OBDII compliant and has the D shaped connector in the passenger side footwell on the center console side.

Hope that helps.

There are early build 95's that are not OBDII compliant.

D-shaped? Mine is just square

I have an early build '95. Perhaps I don't have OBD-II compliance? Odd...I use the OBD-II scanner at Advance Auto all the time and never have problems.

Is that documented somewhere on the org? I can't see them possibly changing something that large part way through a model year.

omg....yes ALL '95 maximas are OBD-II. the plugs are just in a different place than the 96-99s.

Also, what would you consider 'early build'? My build date is 02/95, and she's got OBD-II.

EDIT: Here we go - http://forums.maxima.org/showthread....arly+build+obd

All OBD-II. But seriously, to stop this **** - the plug in the fuse box next to the steering wheel is CONSULT, the one on the passenger side is the OBD-II connector.

Oh god, if people would just search/read.

But there was one nice little quote from that thread:

As far as that connector on the passenger's side, that is the connector for the transmission computer. I had a Nissan technician once riding with me and he plugged the consult tool into this connector plug on the passenger's side. Here, when the car is driven, he can monitor the RPM's and how the car shifts.

That might be true on the 95s. On the 96s and newer the OBD-II port is right near the fuse-box on the drivers side.

I have an 03/94 and its still OBD-II. The OBD-1 95's are similar to the Saskquatch, people claim to have seen one but forgot to take a picture.

ALL 95 maximas have a OBD2 port. My for example is an early 95 made maxima. Built in 94. Go to your passenger side, duck underneath where your feet usually are, look towards the inner side (ECU, RADIO, Shifter SIDE) There is a plastic cover with 2 plastic clips. Remove the clips and towards the back side (towards the shifter direction) on the top corner will be the port.

Do you have a picture of where the OBD-II port is supposed to be? And when was it manufactured?

Without proof, I call

womp womp, I can get a digi camara from my girlfriend.. My car is broken its not going anywhere anytime soon... You can also step outside and open up your passenger side door, crouch down to look underneath your dash, Locate the ECU remove that plastic cover and bingo there it is................. But you want proof anyway, sooo give me an hour or so

I've used my obd2 scanner on numerous 95 maxs, and up, including my 99. So unless I see some actual proof of a 4th gen max being equipped with obd1, this theory will be tucked away in the dark part of my brain, where rarely accessed data resides comfortably with Santa, the Tooth Fairy, and the Easter Bunny.

In 95's under the steering wheel there is a 0bd1 connector BUT! passenger-side by the ecu is the ob2 connector. Don't ask me why I heard its like obd 1.5 or something.

I'll have to look when I get home.

So what you're saying is...perhaps it's an OBD-I architecture but with OBD-II stuff implemented and useable, more than likely preparing for the following model year.

I never even knew I had an OBD-I port. I've always used the OBD-II when I wanted to pull codes.

this is only for 95 maximas. I have the early made 95. pull out your fuse box on the drivers side duck down look in there to the side somewhere there is a obd1 connector port, its not held in place its like hanging unless someone broke my braket to hold it?!

Pretty sure I saw it hanging there the other day and wondered what the heck it was for.

That is the consult port, pull off the cover on the drivers side on the floor and you will see the obd-II connector.

Sorry passenger side you are correct. Consult is in fuse box and obd-II is on the pass side right beside the ecu. This only applies to 95's.

Damn don't you just love it when a 16 yr old is right. Hey I have no problem with age, we are never to old to learn. We just have to be adult enough to admit when we are wrong.

Never knew it was called the consult port, my school did hook up the obd1 scanner in that port.. Makes more sense now. But yes, I have been right in this thread, Most people don't bother to realize that pics dont justify everything, just get on your back and check lol.

Maybe I didn't check enough, but I never saw another port to connect my scanner. The first 95 max I ever attempted to use my obd2 reader on, I checked under the steering wheel for a port, which is where it is on my 99, and when I couldn't find it there, I looked around the ecu and found it on the passenger side. Since the port I found on the passenger side worked flawlessly with my reader, I assumed it was obd2, and looked in the same two spots for a port everytime I hooked up a reader to a max, which there always were. Regarding the Consult port, IIRC, my 99 has one right next to the fuse box. I haven't looked in there in a while.

Yes I did connect a OBD1 scanner to the consult port, I did assume that was the OBD1 port, but it didn't make sense why there was an OBD2 port on the passenger side next to the ECU. Not sure if in 96-99 they relocated the port for OBD2 under the steering wheel. OBD2 was manditory for every vehical in 1996. The codes and ports would be the same in every asspect. Over some time as OBD2 got more advance more codes were added. Now for when OBD3 comes out and what will it feature will be another story for itself. All I can provide is that it will monitor and record live data, it can also be used to send information back to a dealership. Kinda like on-star your whole life is being recorded. As for codes im not sure will be added to the list.. Im not sure if the ports will be the same. I will have to talk to my co-worker who is taking classes on OBD3, so he would know best.

If any of you are interested you can buy a consult interface that will do much more than the OBD-II readers. http://www.plmsdevelopments.com/consult_if.shtml

I have one of these and it works great. You can even do 0-60, 0-100 tests etc. You can turn you radiator fans on and off, change timing and a bunch of other stuff. However the readings will revert to stock when you turn the car off.

What do you mean you "used" OBD-I? Where was the plug located that you used, and what did it look like?

The plug location is why many people "think" they have OBD-1 in the first place. OBD-2 was not MANDATED until 1996 model year, in that year is when they STANDARDIZED where the plug HAD to be located. Before 96 model year, cars could have OBD-2 plugs in other locations, they didn't have to be in the "standard" location until 1996 model year. In 1995 they could have put the OBD-2 plug in the trunk if they wanted to. That doesn't mean the car is not still OBD-2, it just means it was made before OBD-2 was mandated and standardized.

it was an obdI plugi believe it was next to or in the fuse box., thats all i remember. When you get a smog check done in california they connect a comp up to your car through odb. as for the build date i have no idea i sold that car over 2 years ago...

the "obd1" plug in the fuse panel is not true OBD-1 it is just a diagnostic port to connect to. from an aftermarket scan tool or OEM scantool. i believe the adapter for snap on is called NISSAN-1. I believe in an article i read you can reset the pcm by jumping two pins in that port, and you can also read ABS codes.

You cant have 2 computer systems. You either have 1 or the other. If you have the 16pin connector (obd-2) then you have obd-2. If you have both connectors, then your car is still OBD-2.

The other connector is the Consult port which you can hook a consult interface to. They are available for purchase and do much more than an OBD-II reader. I have both and there is a URL in my previous post where you can buy them for approx $100.

It had no OBD-I. I will place money on it. They probably used the CONSULT port, which people have claimed earlier in this thread that they have used the same way as an OBD-I port (i.e. it's not a true OBD-I port, but OBD-I scanners still make use of it).
