OK, I seem to have all the traces of an alarm on my Voyager, LED on the dash, all the door ajar switches, Warning on top of the dash saying Alarm Setting.... but I can't make the lights flash, or horn beep on activation, plus if one door is left unlocked and opened after arming, no alarm goes off.

Can someone shed some light on this??

 

hmmm i would have to guess that your BCM does not have VTSS if so this is normal. Do not try to get a bcm that does have VTSS or you'll have to buy a pcm too.

 

I thought that, maybe it had been disabled, as I can't activate the audible and visual warning on door locking either.
