H2 car alarm

[dougie]

Last night for no apparent reason the car alarm on my 2003 H2 went off. I checked and found all doors & windows were closed, shut & locked. Has anyone any suggestions what happened? Thanks.

Maybe one of the door sensors or hatch sensor is going bad and made the computer think a door/hatch was opened triggering the alarm.

If a proximity or shock sensor is installed then you are lucky it only happens once .. Mine goes crazy every time even at night for no reason ..
