The Bordmonitor is shutdown when ignition off message is received.

After ignition is applied my BM starts to send: F0 BM 03 ...68 RADIO 01 'status request' CS
-> It is checking for the radio.
When I remove the radio from kbus the LED turns off. -> If the radio LED would be on the BM will switch it off when the radio doesn't answer to the message.-> The ignition message is not related to this BUT the 16:9 BM likes to get the ignition status message regularly. In my logs it looks like it even asks for it (ID 10h) when the status of the ignition line changes.
