2004 S60R, sometimes I get the alarm service required message right after starting the car then it goes away. Is this the siren module problems I have heard of? Is it ok to ignore it? Would disconnecting the battery help? Is everything still locking? Will I have problems getting into or starting the car?
Thanks for any advice.
 
when I get to the shop this afternoon...I'll pull the TSB's and post what I find...
IIRC you are correct in that there is / was an issue w/the alarm system....

*UPDATE*

SCM contains a battery that is charged when the ignition is switched ON...
will run "10 cycles" before discharged...it cannot be replaced as a service item
requiring the replacement of the SCM...

the REAR ELECTRONIC MODULE does yeoman duty for most of the alarm chores
and process signals from all the sensors / switches as well as co-ordinating with
the CAN communications with OTHER control units....

PM me if you need added info.....

Common problem. It is located behind the washer bottle on the passenger front corner. Some people remove the bumper to replace it and some drill out rivets and pull the fender liner back. The siren itself is about a $200 part. If you need something to keep the alarm from going nuts a few times a day check out the fuse panel and remove the corresponding fuse. This will keep it from providing power/recharging the defunct battery inside the module.

Everything worked fine in my car besides the sunroof with the bad module. I had the code on my dash for about 3-4 months before i finally replaced it.

I have had the front bumper cover off a few times. Thanks for the fuse tip. Any chance the battery could be replaced? I never use the sunroof anyways.
The car has sat without being driven much lately, maybe if I drive it more the battery would charge and the problem would go away? I wonder if I could hook up a regulated power supply to the main battery and turn the ignition switch to the run position and let it charge the siren battery, or would that cause other problems?
Thanks
 
the usual problem to my understanding is that the rechargeable batteries begin to leak. I suppose you could do like the guy on MVS, but its much easier to just replace the module.

If the car is sitting, just pull the fuse and it wont give you any problems. If you drive it you will still get the "ALARM SERVICE REQUIRED", but everything else worked fine to my knowledge.
 
Your MVS url is not working, it brings up MVS and says sorry not found.

Edit: I found the thread you were referring to with a little search.

I have heard/read this as well...

Our '09 v50 was getting this message, but a deep charge of the main battery stopped the message from appearing, at least at the moment. :e-shrug:
