Hi, the most likely cause for this problem will be Hood latch or door switch.
what is happening is when latch is loose or misadjusted it will move as you drive. Or even if vehicle is parked vibration created from passing car or truck can do that. Find the switches(part of the latch most of the time) and just bridged the 2 wires. that will tell the alarm that switch is closed and will deactivated. isolate them one by one and you will find the problem. I am suggesting you start with hood lutch. This is not 100% guarantee of the problem, but that is what is wrong most of the time. If you scan the alarm . fault codes will tell you what is happening.
thanks palvin i will try that and let you know
