95 S14 Code scanner will not connect to read codes

[Wyteboy240]

I have a 95 nissan that came with the ka twin cam. I got a check engine light back in the day when I first got it and hooked up the scanner and with no issues it read the codes.

Then about 3 months later I go to hook up the scanner and it says can not connect, I even tried 3 other scanners. All say the same.

I recently swapped motors to a sr and it would be nice to see if I have any trouble codes.

And I know there's dispute on the 95 being a hybrid between obd1 and obd2 but mine is for sure obd2

Anyone have any clues what my problem is? I've researched for a few months and haven't found anything

So are you having troubles with the KA or SR?
If it's the SR, did you wire it properly?

[compactfean]

Sr isn't even compatible with obd2. You will need to use the obd1 port, and that's if the wiring was done properly to keep the ecu consult compatible.

@asoomal: it started when I still had the ka in the car. I don't know if maybe there's a relay or a ground or something I need to replace?

@compactfean: I don't mean to sound dumb but does my car come with a ob1 consult port?

Btw I'm pretty sure it's not my wiring though because it was a brand new harness for my car and everything. I may just be overlooking something

[compactfean]

The car does but depending on who wired your swap may and may have not wired it up for consult. Google consult port and you should be able to find a picture of it.

Awesome thank you. I installed the wirin harness myself and there was no console port attached to the harness or the ecu or anything.
Ill let you know if that helped

[Wyteboy240]

So I finally found the obd1 port.

Would I be better off buying the cable that connects to my obd2 scanner that adapts to the obd1 port or should I just not be cheap and buy the correct scan tool?

Nissan Datascan.

[compactfean]

I have a generic consult cable made by ecutunerguy. Works wonders. I just had to download the software online and buy a usb to db9 adapter for my laptop.

[Wyteboy240]

Ok for sure. Hopefully I can find all that stuff for a decent price. I was thinking about buying a cheap little laptop to keep in the car just for that reason. Ill let y'all know how it all works out
