So I have owned my truck for almost a week now and yesterday, at about 2 Am my alarm went off, so I went outside and hit the panic button and turned it off. 20 minutes later it went off again. I ended up disconnecting the battery. Today it drove fine and the alarm never went off until about an hour ago, which was 9 pm. Does anyone have any idea what would be going wrong? I know it isn't someone pulling a prank because two days ago I was out by my truck in broad daylight and the alarm went off. And no my keys weren't in my pocket. Please help me!

 

uhh maybe a cat jumping on it

 

It could be your magnetic resonance detector. Mine was messed up and if you looked at the truck the wrong way, the alarm would go off, even if it was on the lowest sensitivity setting.

 

what kind of an alarm? The shock sensor may be set too sensitive just like karpe said.

 

ok i had the same problem...the door pin gives off enough off a ground connection when the doors shut for the alarm to figure its open..they put a relay in there and havent had a single problem..alarm works amazing now..cost me all of 15$ but it was exactl;y the same about ever 2 -5 hrs it would randomly go off

 

the GEM module "wakes up" every so often. This can be fixed by switching yoru door trigger wire directly to your dome light. Thats what i did

 

i tried that with mine the 1st time i installed it and i couldnt figure the damn thing out....Hmmm maybe thats why i dont specialize in alarms lol

 

my alarm is always set and never comes on when my cat jumps on i was checking it to see ho sensative it was and i hit it hard on the hood but not too hard and it never came on....is thier a way to change sensativety....i really kinda need it now cause theres a few ppl pissed off at me....

 

Diode Isolating the alarm is pretty easy, at least the way I have mine setup.

 

what is diode isolating?

 

every so often, the GEM sends a signal out to the door locks. if the alarm sees activity on the door lines, it is going to go off, if the alarm has not been turned off by remote.

Putting the diodes inline with the alarm ouputs, the diode prevents current from being forced back into the alarm, so it thinks the doors are closed.

 

How would one diode isolate it? Where can u buy theses? And how would one tap into the dome light w/ the door trigger wire? What colors are they? Thanks cuz im about to shoot my truck cause it likes to go off ALL the time

 

bringing up a 2 year old thread.... hillarious.

 

true.. but at least it shows he is searching, which is something not many people do nowadays

 

Thanks! I always try and search b4 I ask a question!! Any suggestions??

 

2 weeks later and still no reply haha. im having a somewhat similar problem. started out the same. so i just stopped setting my alarm for about 4 days. went to try it again. and it stopped going off. dome light and exterior (Third) brake light stopped coming on randomly. BUT! with the alram set. i open either door. nothing. with the alarm off. i open my doors. the lights dont come on, so now im trying to figure out how this is all tied together so maybe i can figure this whole thing out.

 

WD-40 on the door sensors inside the door jam

 

doesnt work for me. ive taken the sesors out and cleaned the crap out of them. still nothing. im thinking its a fuse or relay gone a-rye :P any help to find them is appreciated.

 

Sleep in the truck. You'll know when it goes off.
