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

while driving it constantly changes a lot, and 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 transmit any data using this method, so I'm looking for a different solution.

"Any ideas or tips are greatly appreciated! "
