OBD port fault

[popuptoaster]

Anyone suffered a fault with the OBD2 port on the car?

Got my ELM327 the other day and have found it wouldn't talk to the ECU, I got my bro in law to stick my car on the scanner at his garage and that scanner cant connect either so it looks like a fault on the car somewhere.

Any ideas?

i have that reader (the bluetooth one), i thought mine wernt working either but it turned out to be the com-ports needed re configuring.

the above may not be relavent if you dont have the bluetooth or your using a phone to pair it..

What car and what year?

They're not all OBD compliant until after 2000 for petrol engines, 2004 for diesels IIRC.

Mines a late '97 registered 940, i thought everything after '96 was OBD2 compliant?

i'm afraid you've got no chance, even 850's are fully compliant. I believe their's a few cheap generic code reader (Draper springs to mind) that work, but most don't

§§§§§§, typical swedes lagging behind, I expect they spent 4 years longer than everyone else testing it. lol

knowing Volvo its probably stronger than any other OBD2 port tho lol

If my car is not fully OBD compliant, is it still possible to map an 850 through this port?

The only output you get from the port is a sequences of flashing lights that you then interpret as a fault code i.e. 1-1-1-1 is no faults. You can build a code reader and the details ar ein the 700/900 section on the VOC forum.

cheers, no good to me, I wanted to use "Torque", never mind. I tried the scanner on my mates car and it works fine, i guess it may come in handy for something else.

The late numbered ecu ending in 98* are supposed to be OBD2 compliant. Will try my brother's code reader and see what's what.

Hi, ive got a similar issue on my 99 awd, looks like the elm cant talk to the port as torque keeps saying cannot interface reboot phone etc.

If i work it out ill let you know how i did it . Might help.
