Chevrolet Tahoe Hood open warning on dash and alarm sounds?

This problem was noticed on many Chevy models year 2006 and 2007.The car dash will show hood open warning on Dash and alarm starts honking with all interior lights coming ON.There is a certain GM bulletin that can be related to this issue. This may be due to moisture intruding the door latch switch. This may affect the electrical function of the latch and cause the conditions you just mentioned. And the replacement version has a new latch cover material.
The vehicle's body control module (BCM) monitors inputs coming from all the doors. Obviously at one point it is receiving false signals that can trigger your alarm and interior lights, and even ajar messages on your cluster. The question now is which of them is giving this false signals. Is it from a component or the wirings?
Whether your situation is related under this bulletin or not, you can do your own visual and manual test to determine which door is the culprit. But in case you have a hard time figuring it out, it is better to have it tested by a GM scan tool. It is like you have another BCM in your hands, but you can be able to monitor and read the datas on the screen. It will be much faster to isolate the trouble.

This details will help you.
