Does anyone here know about the Factory installed Security system that comes with Honda Accord? My car Security system gets triggered randomly on its own and keeps blaring till the battery drains out, or I use the remote to shut it out. I had taken it to the Honda dealer and they could not figure out the problem as the Alarm did not go when it was with them > i need to disable the Security. Any ideas?

 

I can't help with this but am hoping someone else can because I have the same problem. My 99 Accord did this the other day. I locked the doors, after about 1 minute the horn started honking. Of course, it's random (only done it that one time, stoppped afer I started the car) so I don't expect a garage to troubleshoot it.

I noticed a few nights prior that alarm would not arm, like when the hood is up, for example. I started the car, shut it off, and I got it to arm... have to think the two are connected....

 

Been doing some research on this and am begining to think, in my case, that it is the hood latch/switch. I had the hood open the day before I started having problems with the alarm not arming. Then a few days later, I had the situation where it armed but the alarm activited about a minute later on its own.

You might want look at your hood/trunk as the source of the problem. Any one out there know how to troubleshoot this problem?

 

Thanks Silversport. The Hood latch is a bit sticky and the canle to the trunck is broke, so maybe this is the problem. Let me get this fixed and see if that resolves. Appreciate your feedback.

 

if all that fails just disconnect the brain of the alarm

 

do you know how to disconnect the brain of the factory alarm in an EX? I'm not sure you can. I will do this if someone can tell my how. Right now, I have the horn relay pulled in case in decides to go off on its own again. That is not a good solution because it will still run down the battery... and it's not safe to drive around without a horn....

 

Its actually illegal to drive without a horn isnt it?

 

actually the Ex alarm is part of the passenger side multiplexer if removed most of the functions like power windows won't work! anly thing to do is groung the disarm (blue wire) On the EX the wire is located at the drivers power window switch. if grounded it keeps the factory alarm disarmed or short out the hood switch so it thinks the hood is always open and not arming.

 

arsh14 - sorry for highjacking your post.

stereo - thanks for the reply. I might have to ground the blue wire on the power window switch for the short term because it is getting worse (happening more oftern).

I'm pretty sure a bad hood switch is the source of my problem but I have no idea where the switch is. Is it part of the latch? I don't see a pin style switch anywhere under the hood.

 

it's the on the hood latch if you look closely at it you will see a 2 wire plug if you unplug it the alarm will think the hood is closed...if you short the 2 wires together it will think the hood is open. you can try it unplugged first then if it still falses then short the 2 wires on the plug so the alarm thinks the hood is open and not arm but remote will still unlock & lock the doors.
