ODB2 My Ass! Volvo 850 1997

[WillT5]

Hi Guys,

Just want to share this because i found out the hard/loooooooong way:

I have a 1997 Volvo 850, i have bought a usb odb2 cable (Elm 327) and a serial one. For the serial cable i had to search everywhere for a really old laptop with a serial connection, which i managed to borrow. Got hold of the VOL-FCR software but i still cant connect to the car! I noticed some people said you would be able to connect to the car with the ebay Serial cables, well you cant!

Im really stuck now

Hope people find this useful

Will,

850 od2 connections dont work anyway lol

How the hell else are you supposed to get the Service light and codes cleared. Go to the dealer? I was quoted £100 for a diagnostic session. Screw that!

Thanks Volvo

you can read the codes with this LINK (https://www.box.com/shared/oy63haaef2)

theirs a special sequence to resetting the service light, hold the trip reset button then turn the ignition on for example. Can't remember the exact thing but should be able to google it

Apparently 96 to 97 this wont work :(

You might need to switch some wires at the OBD port in order for the generic readers to work.
The K-line is not in the right places.
Now.... where did I put my schematics.

Ive had VOL-FCR working on my 1995 850, I also got it working on t5pete's 850 using a usb obd2 cable...

My January 1997 V70 T5 is OBD11 compliant.......i don`t think you can get much earlier than that??

Although 850 are not V70`s are!

I went to a local auto electrical (local to ME - LOL), it was £38 for a diagnostic read, printout and code clear. My garage always resets the service light as part of the 5k/10k Service schedule, its not itemised, and the bill is usually only £100 or so including incidental items.

I would keep looking for a good local side street Volvo specialist.

Mine is definitely obd2 compliant my obd2 scanner works on it too

Thanks for the Replies guys, Was it the Elm 327 you used?

I cant get it to connect with the Volvo Software or the Diagnostic Freeware :(

You can build your own reader, bit more basic than hooked up to laptop. But it works.

Link here for it http://www.volvoforums.org.uk/showthread.php?t=46943

Here's mine. It works on my 96 850.

thats the same diagram (description re-written) that i posted earlier, & says doesn't work

[WillT5]

Thanks for the link Mr Sheen, il give that a go if i cant get the software working

Just for information im using an Elm 327, and VOL-FCR 1.3.6 - Is there a newer/updated version?

Still cant get anything to connect!

[WillT5]

p fandango - I meant the reset sequence you described, ive been told it wont work on 96-97

[JUDGENINJA]

Yep later models do not link, unless you've got the proper software. My 1997 850 only even worked at the main dealer. I should try Dalhouse's code reader unit one day as it is specifically for Volvo's only

[shepbomb]

I'm using my old generic usb obd2 lead which I used to use on VAGCOM, BUT IT DOES WORK, if you were closer I could set it up for you

[WillT5]

1997 looks like its a problem then, thanks for the info JUDGENINJA

Thanks for the offer Shepbomb

Maybe this is why the car was so cheap, the §§§§§§ knew 97 was a problem with odb ;)
