Thank you for that elaborate answer. I read quickly through it, I will read it a little more carefully later today.

In the mean time your description had me wonder about the function of pin 15.
If I look at the "Idling" column in the pinout diagram, two things stand out:
- pin 14 is Ulow when the A/C is off and Ubat when it's on
- pin 15 is Ulow when the A/C is off but Ubat when it's OFF/ON

That last thing seems to suggest that it's the transition from off to on that's accompanied by Ubat on that pin. Also, in the description the word "prepare" is used.

Those things have me puzzled a bit.
