CAN Bus Pinout for BSI 9806687980 & OBD2 - 2015 C4 Picasso

Unread post by santosc »

Hi everyone,
I'm diagnosing a CAN bus fault on a 2015 Citroën C4 Grand Picasso 1.6 Diesel.

I have two quick questions:
1-BSI: The BSI is a Continental, part number 98 066 879 80. Can anyone confirm which connector and pin numbers are for the main CAN I/S bus?
2- OBD2 Port: Is the CAN bus resistance on this model measured between pins 6 and 14 of the OBD2 connector, as is standard?

I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!
