cannot find the immobiliser button

From CEM to VEM, from LED to lightbulb and more. If you have an electrical problem, like a broken info-centre, search for answers in this category. This is also the place to be when you expect the problem to be of an electrical nature...

cannot find the immobiliser button

Post by nigeltowner99 » Fri Nov 23, 2018 2:42 pm

Volvo 480 1993, mechanically sound but has demobilised itself and cannot find the immobiliser button. Have tried Behind glove compartment but not there. All circuits have been checked, but not sure what else to do. Any guidance to find immobilisation switch would be much appreciated. Or maybe even a picture of the button and where it is please

ours is a two litre 1993 ES but NOTHING like an immobliser fitted, maybe the later models (or more upmarket) had them?

I assume key unlocks the car and engine turns but won't fire?

or only doors unlock and nothing beyond that . .. . . .

I had a sneaaking suspicion that the flashing red LED was linked to the door lock, when door unlocked LED on dash-board went out, nothing fancier than that :wink:

the LED just meant that if you opened (or closed) the doors WITHOUT unlocking then the alarm was triggered, try leaving bonnet open , lock car and close bonnet, ours trigger sthe alarm , similar if car is locked and reach in through open window to pull boot release!!!

I hate to throw a spanner in the works here, but unless (1) you have genuine remote key fobs which means that an up-graded system was fitted by Volvo at some point (probably when new), or (2) an after-market immobiliser system has been fitted, then you are looking for something that does not exist.

As far as I know, the 480 never had an immobiliser fitted as standard. Certainly I have had a number now from 1988 model to 1995 and various points between, and none had an immobiliser. Following the 1993/4 facelift the 440/460 gained a remote fob system on some of the higher spec models and this included an immobiliser, but (I guess due to the small numbers being made by then) this was never added to the 480.

The standard set-up is key-operated central locking and is pretty basic. This arms the alarm and the red LED flashes. The alarm (single horn note) will be triggered by opening a door, boot, bonnet, or fiddling with the ignition:
    Unlock the car with the key from the driver's door and both doors unlock and the alarm is deactivated, and the red LED stops flashing.
      Unlock the passenger door with the key and the alarm is disabled to that door and the LED stops flashing, but ONLY the passenger door is unlocked. Reach across and open the driver's door from the inside and the alarm will go off.
        Unlock just the boot with the key and the alarm is deactivated to the boot only. The red LED remains flashing and opening any of the doors or bonnet from inside will trigger the alarm.

        I can see that you have - quite sensibly - been looking at 89/480's thread about central locking, but the behaviour he described with his car is very strange to me; it is well out of line with the above and sounds almost as if someone had swapped the systems over between passenger and driver's doors, or something. I do not think that post will help you.

        So my suggestion is that if your car won't start, the problem lies elsewhere - there shouldn't be an immobiliser to be causing the problem. Have you read the fault codes from the box reader on the left strut pillar? Otherwise if you can give a bit more detail about the problem I am sure between us we can help!

        Hi David, thanks for your feedback, it is much appreciated. The local garage has done their very best, I have asked them to put it back together as best they can. I am then going to look inside the drivers door panel (as this all started when we had an issue with the drivers window). If I may I will post photos of anything we find as your views are a great help. Best wishes Nigel

        Thanks Nigel.

        That sounds like a good plan Nigel; I am sure we will be able to offer further ideas on here with photos. Whereabouts are you located - anywhere near York area?

        Good luck!
