Guide: Wireless Lock Alarm components removal

[RicV40]

Hello,

the fobs of my Volvo V40 phase 1 are not working. The central locking works with the key and the switch in the center console.

I´m now wondering if my Phase 1 also got a Lock alarm control unit under the stereo.

If not, what is the alternative Phase 1 unit and where can I find it?

I would be grateful if you can answer my questions.

The car is a Volvo V40, 2/98, 1.6l, 105PS, 9101-765, LHD.

Greetings
Ric

On my '98 the unit is under the dash, in place of the CEM as pictured in this car. Alarm module was moved to the center console in later models.

Thanks, so I will first look under the dash next to the steering wheel.

Is the unit also called "lock alarm control"?

As ww1dm1 has already said, the lock alarm module on earlier Phase 1 models (1996-mid 1999) without the CEM, is behind the cover on the driver's footwell

The module is quite reliable and does not normally fail though.

Should be if you have an alarm on your car. The module is very similar to the one on P2 cars.

Hi, does the alarm control unit contain the infamous battery for Phase 1 cars? Unfortunately the photo links are dead, but think I can manage based on the descriptions. Would love to know if this is where the alarm battery is on my 1997 v40 (it was not under the main battery). Thanks!

No, the lock alarm module is just a box with relays, responsible for locking unlocking the doors. On the early phase 1 models, without the CEM, the lock alarm module is located on the drivers footwell, in front and below the immobiliser module. The battery for the siren on your car, should be under the battery tray. Siren and battery are all in one and it's a squarish unit. Can you post a phot of your alarm siren?

Thanks for the reply Gatos. Under the battery tray all I could find was this horn, connected by a 2-prong wire that led under the airbox into a larger bundle (couldn't easily trace further but also didn't see a square alarm module anywhere). This horn doesn't seem like it would container a battery, nor did it's removal have any effect on the alarm circuit and flashing lights.




The alarm control module (grey box) I found under the steering wheel, about near my left knee, by removing a plastic shield. Unplugging it has solved the issue of driveability for now, as the flashers for the alarm are now disabled. Manual key entry only now of course.

Images didn't seem to upload. Here you can catch a glimpse before I dispatch it to the bottom of the Baltic Sea.

That's not what the genuine should be like. Pasrt number is 30820037. This is what the early Phase 1 should be like:

Is it possible that someone has fitted some sort of aftermarket alarm?
