Distinguishing between Transport Protocol TP1.6 and TP2.0

Hello everyone.

How can I tell the difference between a TP1.6 and a TP2.0?

Unfortunately, I can't find any information about the control units.

Best regards, Marco.

Hello,

either through a list specifying which CAN IDs are available for which protocol in a particular vehicle.
For example, if the CAN ID is 0x0351, then it corresponds to TP1.6, while if the CAN ID is 0x0359, it corresponds to TP2.0. Depending on the vehicle, this may vary, and you would need to create a database that maps each vehicle ID to the corresponding transport protocol.

Alternatively, you could simply attempt to establish a transport channel and then check whether the opcode 0xA3 (connection test) works on that channel or not. TP1.6 does not have a connection test.

I recommend ISBN 978-3-8348-0907-0 ("Bus systems in automotive engineering").

Okay, that means the messages themselves are completely different.

Are you just saying that the IDs are different for each piece of information?

Okay, here's the translation:

"So, for example, if I have an engine control unit (ECU) with TP 1.6 that sends a message, say 0x380, and I receive that message with a freely programmable display using TP 2.0, and I program the display to interpret the information contained in 0x380, will that work?"

Let's say the structure of the news is similar. Details can be found in the book.

The book is ordered, I didn't think I would buy another book in my lifetime .

Okay, I'll let you know.

Hi everyone.

I purchased the book in the 2014 edition and I highly recommend it.
