J1939 Stop Broadcast

[Marbek_Elektronik]

Hi,
the Engine ECU sends me a lot of messages after started it (Broadcast).
What is the best way to stop this?

There is a comman Stop Broadcast: DM13: 0x18DFFFVA (VA=vehicle address)

Is it OK to send it one time? Or do you suggest to send it 3 times to be sure, it stopps broadcast,
or send it every second?

Thanks in advantage!

Hello Marbek,

I do not know what engine you got but for sure you need the document from the manufacturer that will tell you what the supported PGN are.

In that documment you will know the details of the PGN, I mean if its broadcasted (how often)or if it is broadcasted ONLY on request.

from my understand you cannot stop the broadcasting of the messages unless the ECM is configured for that or in other words all supported PGN are broadcasted ONLY on request

What engine you are working with?

Regards

Antonio

Its Kubota motor and a Bosch ECU.
By switching power to the engine ECU it sends a lot of messages every 50ms.
By sending command DM13 , PGN57088, this procedure is stopped and
the EECU sends messages in normal way,
some PGNs every second, others in other time intervals.
The question is:
Is it OK to send only one time to the EECU to stop broadcast (DM13) ?
Or is it better to send DM13 every second?
