98 850 T-5 no crank with key (Thread now has additional immobolizer info)

[RedBrickCollector]

My LED works the same way as Misha's. The car came with an extra blank key, maybe it was never used as there should be a chip.

This is how a chipped key for 850 & s,v,c,xc70 looks:

Mine works like this...
Led starts flashing immediately as you turn engine off.
Led turns off as soon as you turn the key to pos.II.
When i disconnect immo2 box connector...led lamp by the windshield is not working...when i plug it back...it starts to flash.
Car have aftermarket alarm system installed back in 2000 when i bought the car and have a separate led installed in the line where Tracs,Info...etc switches are and that led flashes only when alarm is armed via remote.

Car was equipped with Guard Alarm II from the factory since there were factory stickers on both front doors windows.
210-211 alarm relay is in it's place.

Parts car from which i removed immo2 box,chipped key and ignition lock acts the same like mine.

Thanks for description i keep in mind i went check and i think i just best share in video format how on mine it functions.
*When getting in
*After turning engine off
*Taking IMMO module off

The only numbers which are different on a replacement which is now in the car is the one below main part # 96W16.
I guess that should be a key id.

Okay thanks. Though i have exact same P/N and Software on mine so i am now confused what they done there and or check those led outputs are they active on mine and i just missing a wire here.

That 96W16 on label is 1996 year and Week 16. These boxes does not have coded Engine MIN code so can replace them without problems.


There was some footnote about Led configuration on some countries which insurance required led always but i dont have in memory at all details of about it how it did differ.

...These boxes does not have coded Engine MIN code so can replace them without problems.

Yes you can...but you need a matching chipped key with replacement immo2 module.

Actually no need if you can program chips into memory via locksmith way or via PIN code on IMMO2 systems like i shown on video. IMMO3 is another side story on used keys.

[misha]

Yes i know that...but that is another story.

This is interesting. After temoving the 210/211 relay (alarm) on my chipped 96 R (Euro spec) I don't have a functioning dashbord led anymore.

I removed the alarm because it almost left me stranded in the middle of the night after the FOB decided not to work properly anymore. Fortunately a previous owner had disconnected the alarm horn.
