04 g35 coupe ecm communication
I need some help with my g35 Flood I replace the ECM,BCM,IPDM AND THE VDC module, my problem is that I have communication with BCM AND IPDM but not with the ECM . I check can low and can high system for ohm and voltage and look good I check power to the ECM plug and GRD and I think its fine, this is my 2sec ECM and nothing..I think that the ECM its not bad because I had communication 1 or 2 time for like a minute and that it no more after that, I still have communication with BCM AND IPDM..
CAN LOW = 2.3v
60ohm
CAN HIGH= 2.5v
CAN LOW = OHN TO GRD 1.2K.OHM with negative disconnected
CAN HIGH= OHM TO GRD 1.2K.OHM with negative disconnected.
i don't know what else to check... fuse and relay are good
thank you for the help

How did you test the CAN? Visually how did you know it was the CAN lines?
