Custom text on Fiat Grande Punto dashboard

[corbandalas]

Hi guys,

I'm trying to show custom text on my Fiat Grande Punto dashboard screen. For the project I've used Arduino Uno and CAN Bus shield clone from Seeed. I have attached two wires from shield to B-CAN wires of dashboard at pin 5 & 6 according to eLearn. Currently I'm able to sniff all CAN BUS traffic and in my serial console it looks like:

4214001,0,81,80,7F,0,0,0,0,
621401A,0,5,1,0,0,0,0,0,
4214002,0,0,
4214000,18,3,BE,EC,18,3,F5,94,
C114003,25,C,0,0,8,0,0,0,

4214001,0,81,80,7F,0,0,0,0,
4214002,0,0,
2214000,0,20,0,0,20,0,
4214000,18,3,BE,EC,18,3,F5,94,
4214001,0,81,80,7F,0,0,0,0,
621401A,0,5,1,0,0,0,0,0,
C394003,10,0,0,10,40,
4214001,0,81,80,7F,0,0,0,0,
4214002,0,0,
4214000,38,3,BE,EC,38,3,F5,94,

The first number in each line is CAN-ID of node and the others is bits of data.

Can you suggest me what to do next? Maybe somebody has some experience with analyzing Fiat CAN messages ?
