20pin on an OBD2 scanner???

I have an adapter that has a BMW 20pin connector on one side and a OBD2 on the other. Can I use this to interface between my car and a generic scanner, or is the 20pin only for BMW scanners???

It would be useful only for BMW scanners, but you may use it to pick up what the OBD2 port is already telling you.

Thanks I'll give it a try in the morning. My problem is that my SES light is on, but the OBD2 port isn't showing any codes. I'm using a bluetooth scanner and torque pro on and android tablet. In the past this system has worked pretty well but I'm getting nothing here. Does the SES come on for service intervals maybe? I have a couple BMW scanners and a bunch of adapters that came with the car (one says something like INPA on it the other has no distinct markings) but to be honest I don't have a clue how to use them, I'm not even sure they are compatible with my computer.

I haven't used torque pro yet, so I'm not sure if it can even read BMW specific codes.
If it can't, just go ahead and purchase the $30 BMW Scanner 1.4, you can thank me later

Do you mind posting the link to where you purchased your Bluetooth scanner?

What is this

The 20 pin cable you have is useless without a Obd2 to USB that connects to your computer.

What you do is take that 20 pin port. Plug it to the under the hood port. Plug the other end to the obd2 port and then the USB to your computer.

Now you can scan for AbS, airbag codes.

I got the bluetooth scanner from amazon. I believe it was this one http://www.amazon.com/Excelvan-Bluet...etooth+adapter they are not known to be the best quality, but so far it works for me. The only downfall is they don't send you the password to connect to it, turns out mine was 1234. Torque pro is well worth the $5 you spend for it. lots of uses and it's really fun. It does read most BMW specific codes, even if it says it doesn't have the exact definition it will still normally show a code. I think mine may be a bad gauge cluster, I just swapped this one in because the ses light did not work in the other one, now the speedo does not work in this one.

I have several scanners but the obd2 one I run through my android is the only one I know how to use.
This is what I currently have.


the tablet and the small adapter to the left are the ones I normally use
the white scanner says "BMW diagnostic interface" the bottom says
"BMW INPA + 140 + 2.01-2.10" each of which have a firewire(usb) port under them (three total)
the black one says BMW compatible scanner V1.3.6. One port says vehicle the other says RS232 there is a light that says power and one that says K-line

and then the various cables and adapters.

What kind of software would I need for these. I'm not real keen on sticking any of these disks in my computer, they look like something from Ebay out of china.
