GMC Yukon Denali factory alarm keeps going off Any suggestions?

Answer 1

I looked this up in my Manual for my 99 GMC Yukon, and it mentions adjusting the Shock Sensor. The manual states "The sensor can be adjusted if more or less sensitivity is desired. If sensitivity is increased too much, it may give false alarms caused by gusts of wind or other natural events that may shake the vehicle. The adjustment for the shock sensor sensitivity can be accessed through a hole in the forward wall of the main bin of the center floor console. Using a small flat-tipped screwdriver, turn the adjuster clockwise to increase sensitivity, and turn counterclockwise to decrease sensitivity." On my Yukon, the hole in the center console is right next to the forward end of the multiple CD changer. I used a mirror and flashlight and made a note of what sensitivity the Shock Sensor was currently set, so I knew how much I will change the sensitivity. On my Yukon, I turned the sensitivity a little counterclockwise (decrease sensitivity) and drove and used the Yukon normally to see if the sensitivity was what I wanted, and then turned it a little more if needed. Then it will be set and forget, unless you park in a unfamiliar area, then you know how to turn up sensitivity if needed.
