Hi all.
Today i tried to receive can message from my ecu on the bench , only power connected , no other sensor or instrument.
I used an arduino nano and a mcp2515 can shield
I connected pin 58 and 60 from ecu to mcp shield and i received only messges from the end of the post, repetly.
Maybe the pin 58 and 60 from ecu is only to send data to instrument cluster , but if it is like this what can pins arrived in OBD socket?
I'll tri to find an obd cable to cut and connect my mcp2515 shield directly on pin 6 and 14 on OBD and will see if receive something there or not.

in OBD socket can pins are connected to the gateway or cluster ( eg.Passat B5 FL , A4 8E )

here you have some explanation of can frames ID: https://wiki.openstreetmap.org/wiki/VW-CAN#280_8_10.2F20.28Diesel.29ms_Motor_1
