obd port

ivibmw · 11-02-2012, 06:21 PM

Does anyone have the schematic to the OBD II port for an E90?

My BT tool is not working and it seems to be a good cable. I am getting power and ground from the OBD port, but need to know where the other ends go.

Thank you.

Bump, I took a close look at my OBD port and it looks like one of the pins is bent or messed up. Not very many pins in there for 16 spots. Only looks like about 5 or maybe 6 are used? Is it hard to replace the ODB port? I have plugged stuff in there so many times one of the mounts busted so it is hard to plugg stuff in. Wiring diagram would be sweet.

the obd ports are universal and pretty easy to replace.. let me know if you figured it out or if you need help.

Hey guys did this ever get figured out? I went to install my cobb today and obdII is loose (I think) i need to hold it and kinda push on it for it to connect and hold it there if i let go it disconnects... any idea what it could be? or a way to fix it? When I do hold it and try to install it says cannot connect to ecu could I be missing a pin in there or something?

bit of thread highjacking on my part but can anyone comment. Pin 1 on mine is NOT 12v+ when on. I get no reading. I was pretty thorough.

Pin Signal Description
1 +12V Ignition(in run or start)
4 CGND Chassis ground
5 SGND Signal ground

7 ISO 9141-2 K-LINE engine (ISO-9141 and ISO-14230), automatic transmission diagnostic (in some models)
8 ISO 9141-2 K-LINE IKE/KOMBI, ABS, ABS/ASR, ABS/ABD, ESP, DSC, Airbag and other electronic equipment
9 TD/RPM Engine rotation speed
16 +12v Battery power

where can I buy the OBD housing? I had an Elm wifi adapter plugged in and i kicked it by accident and it broke off where the screws hold it.
