Fitting OBD2 scoket into volvo 850 OBD1

[t5 pete]

I've been asked to possibly fit a obd2 socket into the gul for live date readings after doing a little searching there a bit on info on the net and all point to 3 wires one for earth one for live and the other to b36 K-line to the ecu.
So today I started to fit it but did notice that the K-line wire from the obd2 socket actually splits into 5 wires.

Wire run for pin b36
But as it said it only needs to go to pin b36 that's all ive done once wired in I put the reader on but it just keeps up with no coms weather ignition is on red or weather the car is running its just the same.
Am I missing some thing as to me with that white wire splitting into 5 would they all need to be connected to their correct places to read date?
Any help of info would be much appreciated

That's the right idea, I'd double check everything, is the b block the front or rear section?

[mike 850]

Also what port on the obd connector did you wire b36 to?

[shepbomb]

This is more like it pete an interesting thread

[t5 pete]

OBD2 socket

pin 4 to earth

pin 7 to b36 K-line

pin 16 to live
its my understanding b block is the one to the bulk head

Show off lol ill need to take yours to bits then and trace the wires lol

[MoleT-5R]

probably got the wiring diagram here on the disc that came with vadis, will have a look later and try and find the differences
cost you your wheels though....

[t5 pete]

lol ill do you a good deal on the wheels £600 and ill deliver them to a meet were both at.
On the subject of Volvo cd I have a really good program on my comp in the garage but cannot find the bloody cds and cannot remember where I got it from its got all repair procedures and wiring diagrams etc
now off to ebay to see if they still sell the cds

[MoleT-5R]

just lack the dosh at present, or I would be snapping your hands off, great goods for someone, surprised your not keeping them for a visit to voc's bkv you'd win it hands down

[MoleT-5R]

[MoleT-5R]

[t5 pete]

Yeah I was going to keep them but the problem is with the little mileage I do it would be years before I run the tread off these tyres on the sats but im in no rush and just as happy if they don't sell.
As for bkv I carnt be doing with that having some one nit pick over my car oooo that bolt is a little mucky lol

I couldn't be ar$ed to clean it that much for bkv and stand around kicking tyres all day to find out I didn't win, rather have me foot flat on the throttle getting smiles per mile.....lol

[claymore]

Following with interest as I need to wire an obd11 for the rear engine.

[t5 pete]

Done some reading and also with info from Chris on voc I now need to wire into B5 as well or try it independently with b 36 removed

[mike 850]

Is it a 4.4 ecu?

[t5 pete]

No its 4.3

[MoleT-5R]

found my wiring diagram disc, got to find the password now ........:slap:

[t5 pete]

Well I made the balls up buying guide one of eBay last night I blame you Adrian lol.
Any way to find I have a email off him and got to down load it I thought I was getting a bloody cd

ne worries

Pete the first link I posted says:

Yellow/Brown wire from pin 3 on new OBD socket goes to Yellow/Brown wire from pin 2 of diagnostic box socket under bonnet.

Black wire from pin 4 on new OBD socket goes to earth.

Brown wire from pin 5 on new OBD socket goes to earth.

White wire from pin 7 on new OBD socket goes to White wire from pin 6 of diagnostic box socket under bonnet.

Red wire from pin 16 on new OBD socket goes (eventually) to 10 amp fuse #15

Might be ££££££££ but that's what it says.

No problems

[t5 pete]

Tested B5 and still no response tried it with and with out b36 connected to no difference so now need to.get some more reading done.
Shepbomb when you coming to install the stupid vida.

[t5 pete]

Sorry for the late update but I've got it all working.
Pin B36 is no good what so ever as stated on the net you need to connect to pin B5 and with the Volvo reader it all works giving all live data.

who mentioned B36 anyway?? :uglyhamme

[p fandango]

nice one on getting it working. Does it need to be a Volvo reader & what sort of info can you read live? I want to record as many parameters as possible via a obd2 socket so it can be overlayed onto a video

Yes got to be the volvo unit and it can read every thing from loads to timing to duty cycle the job lot

thanks, but can't see anyway to record the date in the correct format for a video from a Volvo reader :(

I know Torque is not up to much but...

//edit sorry didn't see your comment about Volvo reader

Maybe that means Torque doesn;t work? Maybe Motronic suite can be used somehow...http://socalsaab.com/suites/suites.htm
