Hi There!!

I ve got a 1994 850 GLT 20 V and i would like to know how can i determine if i have the remote unit for that remote door opener. I saw on youtube that it is behind the glove box. There is no such sender unit so i assume i dont have one.
I saw on enbay that they offer OEM units for 50-80 $. Some of them are from the US or Europe. Would that be possible to connect these overseas unit to my Volvo?? And how do i have to connect them??

Cheers heaps!!!!
Elk

    I would say forget the O/S stuff , call Mark ( @Pom ) and get a set from a wreck tha way you get matched key fob so no problems setting one up , plug n play then!
    The wiring for ALL extras and options is already on the car so the plugs etc will be wherever the unit is supposed to be.
    Mark can give you info on special install instructions as he will have pulled one apart.

    I think there are 2 types of systems.

    I think it might have a system up under the dash It hangs off the immobilizer relay.


    The base system is behind the glove box there should be a green 5 pin plug for the receiver it requires the matching immobilizer relay (up under the dash)


    I am chasing down a receiver glove box unit too.. some of the receivers on US cars were Australian made. They are matched to the fob by a FCC no. but IIRC can be reprogrammed to a matching fob with the correct FCC.

    Does your immobilizer light blink?

    I can't help you with the under dash unit.
    try a sig

    Do you happen to have this manual?

    I'm trying to get to the bottom of my alarm/central locking system. I also need an alarm key fob.

    Hi There!!!

    @Nicko: I have a green pin plug with two rows of 5 pins and there is a white and a brown wire connected to it. At the moment it is plugged into a black female plug and when i unplug it and start the engine the lamps for the aircon and the reverse air(?????) are blinking, if i plug the green plug back into the black female plug, then everything is back to normal. I took some photos but apparently i cant upload them here (or at least i dont know how).
    The immobilizer light (i take it that this is the led light in the center of the dash facing the windscreen) is not working at all. When the engine was running and i lock the car there is no light flashing and when i open the car there is no light blinking either. And i never saw that working.

    @SPT940: No i didnt have this manual but i will read it. Cheers!!!

    Thanks heaps everybody for your help!!!!!!!!

    Hi Elk
    I think you have the wrong plug. The photos online are the US version.
    The plug sits on the left hand side of the glove box (if stting in the passenger seat facing it) Australian models.

    4 wires Black red,green yellow, yellow violet. on a green plug.

    the receiver unit then sends pulses to the relays. for lock unlock see below.

    volvoclub.org.uk/tech/service/850/AntiTheftSystem.pdf check page 16.


    You need to confirm what alarm relay is in your car. If you have no working led on the top of the dash you may have a bypass relay in the alarm circuit or it's dead.

    this explains how the base model one works.
    Hi Franz,

    I had a 1996 Volvo 850 some years ago to which I fitted an "after market"
    remote receiver which interfaced to the Volvo central locking system. To do
    this I needed to find out some things about how the Volvo receiver worked,
    which I did by trial and error measurements.

    The connector for the receiver, behind the glove box is designated 4/19 and
    has 5 pins:
    pin 1 - wire black (ground)
    pin 2 - not used
    pin 3 - wire yellow/green (receiver output)
    pin 4 - wire yellow/violet (+12V accessory)
    pin 5 - wire red (permanent +12V)

    The receiver puts out a 100ms (milli-second) positive going pulse on pin 3
    to lock the doors and a 200ms pulse to unlock. There was a tolerance of
    something like +/- 50ms - I forget the exact figure and it is probably
    different for lock and unlock.

    You stated that when the failure began the doors would lock (short pulse)
    but not unlock (long pulse) - you seem to have made a mistake in your typing
    and that's how I interpreted what you wrote. But it doesn't matter anyway.
    It looks like either 1) the pulse former in your receiver is "out of spec"
    and no longer sending the correct length pulse to the car's central locking
    system or 2) the car's central locking system is no longer accepting the
    "standard" pulse lengths for lock/unlock.

    Unless you have a friend who can trouble shoot the electronics for you, I'd
    suggest you get hold of another receiver, buy or borrow one and substitute
    if for yours. If it doesn't fix the problem, the trouble is most likely the
    central locking module.

    Regards
    Barry

    Just a note the remote central locking is a different circuit than the alarm/immobilizer but they interact.

    Thanks Nicko, i think the best way to find it out is to go and see the volvo dealer and ask them what system i have in there............i saw a bill in which was mentioned that the key for the car was cut and coded..........so i think there should be some system in there......but i will go and see the volvo dealer

    They will charge you an arm , leg and half a lung to tell you what you can find out here , Mark knows this shit , others too.
    You may get the answer from the (St) dealer like , leave it with us , come back with gold bars and fine wine and we may have fixed it , or not...

    I'm with Les have a look up under the dash where all the relays are and report back.

    For photos use Photobucket or the like and link to here.

    The receiver is on the other side closer to the door same colour plug.
    But that is not definitely not it
    Take a pic of the relays under the drivers side dash if you can.

    Thanks for posting that Info Nick.
    I've been thinking about adding remote central locking to my 850.
    If the only difference between the lock/unlock is the pulse time I think I can cobble something together to make this work with a generic fob.

    @CamZH

    I've tripped mine to work at the plug in the glove box by hand.
    But my receiver is faulty. But it supplies a signal to the central locking relay and the immobilizer relay. No fancy codes just the length of the pulse.


    I have also seen many after market systems (installed from the dealer?) That goes straight in to the alarm/immobilizer and/or central locking relay slots. I didn't look too close as it was not what I was after. But if that unit is using it's own relays it would not need the pulse length.

    I like the idea of a box that plugs in where the factory box is meant to go.

    I'll need to get my nose in under the dash and check for the relays.
    The other thing I need to fix is the tailgate.
    It can lock/unlock all the doors, but isnt controlled by the others.

    This relay is 9166607, the US market version of Volvo Guard Alarm (VGA) 2.2, it has unlock audio / light signal permanently disabled (eg. no indicator flash and/or horn beep when unlocking) to prevent people jumping into your car with a gun when you unlock.

    I prefer the Scandinavia version (9166157 in black) or UK version (9166477 in orange) instead, which has unlock audio / light signals. UK version has horn signal factory set to continuous (BEEEEEEEEEP) which you need to do if you're fitting a siren with battery backup, but this can be reprogrammed to intermittent (BEEP-BEEP-BEEP) with programming box 1399141 which I have.
    Current Volvos- 1998 S90 Executive (B6304S), 1998 S90 3.0 (B6304S), 1996 965 2.5 (B6254S)
    Previous Volvos - 1991 964 (B280F), 1990 764 GLE (B280F), 1990 764 GLE (B280E), 1990 744 GLT (B234F), 1990 744 GL (B230F converted to B230FB), 1973 164E (B30E)

    So , what can we get here or can these be had via inet or summit?
  • 123 / 23joined Mar 2014
    US version is easy to come by on eBay, while UK relay is also easy to find if you lurk around the UK Volvo forum & wait for someone wrecking a 850 or 960, which happens a lot more often than you think.

    I'm going to pull my glove box out on the weekend a look at mine. It has a Mongoose MSP402 Siren under the bonnet. It has a Volvo Part No. 1222912-6 for 900/200 series.

    The Volvo Prt No.1222887 - 0 is for 850 series according to the front of the Volvo operator's instruction manual that I have for it.

    I'm yet to discover which remote it came with. The one Will posted is a likely item.
