It is 9 bits, so it can have a value from 0 to 511.

while driving, it constantly changes a lot, and it doesn't seem to be related to speed or throttle...

Wake the car while it is parked to receive 0x521 data from the heater.

"1B000010 is an interesting message that I am receiving from the bus when the car is active, but the car doesn't wake up any more than it does when a 0x700 message (or any other message) is sent to the bus when the car is parked."

The heater doesn't send any data using this method, so I am looking for a different solution.

Any ideas or tips are greatly appreciated!
