Prius alarm will NOT stop!

Many cars will trigger the burglar alarm when the battery runs down. I've seen it on GM models and Ford models. I'm not sure if Toyota does the same.

 

I know the reason. You have a faulty alarm sensor. Alarms have a set of sensors, motion/vibration, door/hood/trunk opened switch and pressure sensors. Try disconnecting each one of these sensors/switches, let the car sit for a while, to isolate the one that is faulty. If you disconnect a sensor and this issue stops. You found the fault. Some systems require the sensors to be connection, in such cases, you’ll need to check each sensor/switch to ensure it’s still in spec.

 

Hey guys and gals I hope this helps. My girlfriends car was doing the same thing while playing with the infotainment system it all of a sudden gave me a caution on the screen. (It said caution there is a problem transmission p lock mechanism. Park your car on a flat service and apply the parking break.). Note I did this 2 hours ago and no trouble thus far. So try putting on the e break and see what happens. good luck
