can anyone post a copy of the data link connector wiring diagram for 90-93 Q45's? i cant communicate with my ecu via either dlc in my car!
car: 96 240
ecm: 91 q45; chipped and tuned by carl H
wiring harness 94 q45; conversion done by carl H
so i can power up the consult via the consult dlc (grey connector near fuse panel) and can only access my airbag module. not the ecm. i have the wiring diagram from the car's dlc and for a 94 q45 dlc but it shows the ecm connectors to be totally different and as well the 94' Q only shows the generic obd2 dlc not the consult dlc (grey connector). if anyone has any helpful info i would greatly appreciate it!

Are you using a real Consult, or one of the aftermarket kits?

I'm using a real consult2 I work at the Nissan dealer
And your diagram just shows consult to a pc serial cable? I need the fsm diagram of the consult port to the ecu on a 90'-93' Q45? But thanks for the info looks to be very useful for wiring up your own consult cable!

Oh I see.

Does this help? These are scans out of the '91 FSM.

Yes and no but I figured it out, in the assist the ECM pinout for a 94' Q45 is a misprint and the 95' Q45 ECM printout is correct
