Adding motion / tilt sensors to CMA vehicles

[Pau1ey]

Thanks for this! I bought a cheap used overhead console from Ebay which had IMS part # 31443745. I changed 065 INTERIOR MOTION SENSOR to 02 Interior Movement Sensor and tested successfully with the window down in my 2019 XC90.

If you want, you can also enable passive arming.  It's a good feature has two main functions 
1) Car is unlocked via remote or by touching the handle but door is not opened. After about 30 secs. it locks itself. 
2) Car is left without locking the doors and ignition is turned off. The alarm arms itself after couple of minutes even the key inside.  If someone opens the door, alarm will sound or if  something triggers the motion sensor through a open window or sunroof.

I had passive arming on.

Had to turn it off. Every time I forgot to lock my car, when we went out to it a family member would get to the car before me, see that it was unlocked, and set the alarm off for the entire neighborhood. It was impossible for us to make the transition.

What I really needed was passive locking. Like walk away, car locks.

Tried it for a few weeks but disabled it since we kept setting it off in the garage. I agree, walk away arming would definitely be better.
