VW TP 2.0 CAN Bus System

Guest Free account, no CAN development support

Hello everyone!
'Excuse my German, I am Italian.'
I am studying CAN TP 2.0 protocols from VW. To do this, I have downloaded the diagnostic data onto my PC, but I cannot understand some of the scan tool commands related to the instrument panel, specifically the service reset function.

751 7 1x.00.04.31.B8.01.03

751 7 1x.00.04.31.BA.01.03

751 8 1x.00.05.31.B9.01.03.02

751 8 2x.00.06.31.B9.01.03.00 + 751 2 1x.00

Can someone tell me what they are doing?
Thank you.
Gianni Resta.

Does anyone know the meaning?
I think it has something to do with adaptation, but I can't find any documentation about it...
