There are three types of "request" frames sent out by IHU to see what CDC is doing:

*) Power-up ("Hey, CDC - time to power-up!")
*) Active ("Hey, CDC - you still there?")
*) Spin-down ("Hey, CDC - time to go to sleep!")

To which CDC (BlueSaab) is supposed to reply with a group of four frames.

"Requests" from IHU have CAN ID 0x6A1, CDC "replies" have CAN ID 0x6A2.

In my experience, I *think* I have never seen anything but "Active" requests coming from IHU when BlueSaab is connected to the car. That might be because BlueSaab sends out a status frame 0x3C0 that already says something like "Forget about power-up, I'm active". Need to check my code again...
