Sleep mode

[Syntax]

Is there some timeout when the car enters sleep mode after IT is locked and stops any communication on MS CAN?
I have been logging 048 msg for about two hours and the car still kept sending it (with ignition byte 0x20).

It should go to deep sleep in several steps. After about 30 mins most should be off.

Then there is something wrong in my car that is preventing from going to sleep.
