baby and how many functions. - Toyota Mega Cruiser, 4.1 L, 1999

In short:
It is a rollover sensor - it measures the position along two axes and, when it deviates from the vertical by an angle of more than 80 degrees, cuts off the ignition for 30 seconds (then reconnects it - it’s done, but what if you really need to turn on the ignition in the recumbent position?). That is, the principle overturned - the motor was cut out. After 30 seconds, the ignition will turn itself on. Turned off the ignition with the key / turned it on - if you lie down = delay again 30 seconds, no critical slope = does not manifest itself in any way (i.e. if already on wheels, then the ignition will turn on immediately).
Has the ability to calibrate the vertical (in case of non-standard mounting, sideways, upside down, etc.). We put the vehicle strictly vertically. We turn on the ignition. With one button (more precisely, one wire) we press on the ground for a short time. We observe the indication - after 1-2 seconds the calibration is complete, you can go.
