Mercedes Benz W204 AIRBAG PROBLEM connect
I have a question. I got a W204 for an airbag repair. SD sees everything except AIRBAG. I checked everything. I connected on the table. Power supply and CAN-L - CAN-H. There is no connection. I bought a second SRS module. The situation is identical. Can anyone help?

CAN H/L wires in vehicle good? ECU has proper power/earth? If so and ECU is working should be able to communicate even if ECU is coded to different vehicle.

Until ECU and earth lug is correctly bolted down, the SRS ECU has no earth. If all seems good clean this earth point.
