Hello i have a problem with an edc16 non communication with it at obd port would appreciate any guidance

Non communication with obd port on a edc16 ecu
Any thoughts or guidance much appreciated

Hi,
We need to know what exact car you are working with.


Citroen relay 3ltr diesel registered number NK58HXZ thanks chris

It’s from 2009, so the OBD must be over CAN bus.

Did you connect CAN 2 from ADU to the correct pins in the OBD port?
Did you select the correct bus speed?
Do you have CAN 2 errors?

I have tried them but can’t communicate through the obd

What haven’t you tried?
I don’t understand.

Please answer the three questions I asked.
