My alarm went off completely draining the battery.
As soon as I connected the charger the horn and lights started up again.
No matter what I try with the key, remote, etc. it continues to go off until
I pull the battery cable off.
How can I disable the alarm system completely. I've searched these posts
but not found any clear instructions. At this point, I just want to disable it.
2003 Honda Accord V6 with all options.
Thanks

 

On earlier models, you reset alarm and then disable alarm to stop the noise. I haven't had a factory alarm on this model however.

good luck

 

The security alarm system is part of the multiplex integrated control system (MICU). Usually, the alarm going off is due to a faulty hood switch. Disconnect the connector for the switch (located in front of the hood latch) and see if the alarm stops going off.

 

Thanks for the replies, however neither suggestion solved the problem.
Guess this means get it to a dealer and pay all the money!! If the MICU has to be replaced that's probably hundreds of dollars. Think I'm ready to go back to a Jeep!

 

Is the immobilizer recognizing your key? Indicator light should go on for 2 secs when key is turned to On and go off. When key is turned off, the indicator light should flash 5 times indicating system has reset.

good luck

 

When the security system sounds, the B-CAN (Body Controller Area Network) stores the last input (security breach history data) that set off the alarm.

The dealer can use HDS (Honda Diagnostic System) to access the stored history data to help find and fix the problem. To access the last security breach history, they would connect HDS to the OBD-II port and review the history data by accessing the Security Menu.

You may want to make sure your battery is not really weak before you decide to bring in to the dealer for diagnostic. Battery checks are free at most auto parts shops.

 

You can also try inserting the car key into the driver's door and turn to unlock position to see if it will turn off the alarm.
