Hey everyone, I'm working on my 2002 Ducati Monster 750 that I just picked up.
I think may not getting power to my ECU because I have one immobilizer fault flash (which means it is not communicating with the ECU) and I do not have a the check engine light on when the engine is off. It doesn't behave any differently when I pull the connector plugs off of it ECU as well and I do not hear the fuel pump cycling. The start button also does not do anything (which I pulled apart and tested along with the starter solenoid)
Does anybody have any ideas where to start looking for ECU power other than the fuse? I did pull 12v at the ECU fuse on both sides so I know I have power there. I'm just not sure it's getting to the ECU
So far I have checked and verified the following are functional on their own, off the bike.
-Fuel pump
-x2 relays next to battery
-Starter
-Starter solenoid
-All fuses
-Right hand control switches
I really think its coming down to an issue with the ecu not getting power which is disabling the starter and the 2nd relay which controls the fuel pump/injectors etc. The immobilizer flashing the code saying the serial connection between the cluster and ECU help support me theory.
Does anyone have a PDF of a workshop manual or wiring diagram for the 2002 M750? it seems like they have all disappeared online :/
