Does anyone know if it is possible to turn the front parking sensors on permanently, possibly with the IID tool?
My wifes Jeep does it and I do find it handy in tight spaces.

You can't.
The fronts will only be activated after the rears have been. ... - .- -.

Pressing the button will activate the front sensors. I'd like to get accustomed to doing this while getting into tight spaces, but never think of it in time.

I do press the button but it would be nice if it was always active.

You possibly could do that by wiring in a momentary relay to the 'sensor on' switch which is fed from the ignition or maybe even better, the wire that tells the car to start.
Some electric guru will know exaclty how.

They do stay on after reversing but I don't know what the parameters are for them switching off.

This morning's test revealed that they switch off after a particular speed and also if the gearbox is put into park. Hence auto switching on when starting the engine would be futile.
