no, it's not my transmission! ;)

no avatar with banging the head against the wall here??

oh yeah, here's a better one: :idiot:

actually, idiot is a better word! :lol:

i want now obdI with dtc, and i've an '96!

i'm not gonna take her to the stealership every time the a/c, or dash cluster, or tarnsmission throws a code!

i read a few threads already about a switcharoo between the obd systems, but it seems most of info is about obdI to obdII, so please help me out with this one.

first off, all 850turbos got 4.3, so should I understand from this that the change made after '95 has to do with the harness?

i'm still digging for info about the subject, whataever i know so far is from going through chilton and haynes this afternoon.

i also have a cd with the electrical systems of '95 850, it is next on my list for studying the matter further, but only sunday i'll have some time to do it.

i personally suspect this bullkrap change to obdII and the arrival of vst had only one purpose: so the stealerships can stick it deeper to the volvo owners.

my only reason from not going out in the world and just getting a '95 turbo is: my '96 has a pristine interior and every frickin' accessory on this car works a1, even had the evaporator replaced 2months before the tb tensioner failed!

so without doing the homework, i jumped on it for a great price!

any specific forum/thread/whatever i need togo to?

either way (changing the harness or getting a different car), i know i'll end up with the obdI..

time isn't a factor, i can take my time and do it, if in the end comes to replacing the harness and keeping the car i already have.

i got the guts out in my '96 right now (still waiting for radioator and few hoses so i can finish it up):

meanwhile, i'll do some googling and dig through the repairs thread about this "reversal" to obdI jjob.

much appreciated (eveery opinion, as usual) :excl:

code reader.....ive never taken it to a dealer to get codes read, i have a code reader in the trunk always handy..

It only reads most engine (A2 - fuel system , A6 - ignition) codes. 1995 is the last year Volvo provided both OBDII and OBDI which one can read and reset:

A1 Transmission

B1 Climate Control

A2 Fuel System

B2 Cruise Control

A3 ABS

B5 SRS

A5 TCU (Transmission Control)

B6 Power Seat

A6 Ignition System

A7 Combined Instrument

1996 models got the newer but unreliable ABS/TRACS and had the speed sensor moved from the transmission to the ABS module. There's also the egr in the 95 which was eliminated in the latter years. Not sure what else would make an impact on switching systems.

It's for this reason I conclude that the best 850 for DIY is the '95 T5 (or R of course - and ltd yellow at that!) since it has side airbag, newer switch designs, later 850/x70 center arm rest, and still has the DTC port, and as Alvin mentioned, the older but more robust ABS system.

People fret about the EGR but other than parts are expensive (if you buy them new, lol), it's nothing to complain about, really.

Look for adam oreo391's engine swap OR you could swap whatever hpt turbo from 94-98 and just get a code reader for it. Decent reader wont be more than 150 and will actually tell you what the code is

thanks, I'll look for it.

Also, Harbor Freight has generic ones on sale sometimes for $40.

but my intention is: i want to get away from ever having to use a reader AND have the possibility of reading more than just fuel&ignnition codes

here you go...e8650.gif:lol:

thanks :D

before gettting my jy motor, i dismantled an '95 854 with egr.

i was planning to swap the motor from that car in my '96, but i found this: bad injectors/juju!!!

so this is the car i'm eyeing now for a donor to get the obdI, but if it gets too tricky with changing the harness, i'll fix the whole car (was in minor frontal crash) and have an obdI after all!

It's for this reason I conclude that the best 850 for DIY is the '95 T5 (or R of course - and ltd yellow, and a wagon at that!) since it has side airbag, newer switch designs, later 850/x70 center arm rest, and still has the DTC port, and as Alvin mentioned, the older but more robust ABS system.

People fret about the EGR but other than parts are expensive (if you buy them new, lol), it's nothing to complain about, really.

it's fixed! :)

the egr can be deleted from the system, yes?

The AT difference from 96 onward is no big deal either - later AT with speedo tapped to ABS sensor CAN be used to 94-95 cars with little rewiring. I know, I got a '98T5 AT on my '94.

thanks all, great advice!

(now, i need the avatar with the two happy faces toasting with beer) ;)

Well said. Agreed. :D

It can be blocked off, but unless you have it deleted from your ECU via a tune, or get a '96+ ECU, you will have a check engine light.

I hate to break it to you, but there is a affordable software that allows you to read the Volvo proprietary codes.

The software is called Vol-FCR and requires a (VW) Vag-Com serial cable to work. I've used it to clear my service light codes as well as finding out why my climate control lights are flashing (as I was able to pull codes from that). This software can do climate control, SRS, ABS, Ignition, Transmission, heck even the power seat!.

There really is no need to go back to OBD I setup in the 850.

great, thanks! I'll google it.

i don't necessarily want to reverse to obdI, but i'd realyy like to be able to read more codes than fuel n' spark.
