The ECU 391100-4A300 is compatible with my hyundai porter ii 2009 or H 100 2009. but i lost the wiring diagram of my engine . Is there someone help me?. where i could find the wiring diagram
Sorry can't help with the wiring, though Autodata usually include wiring and pinouts - just wanted to mention these days a vehicle ECU is likely coded and won't work unless it is recognised by the security system.
Testimonial: "i just use that ecu for the engine, i'm researching CRDi engine so the security system that is not important, and i could fix it . but i really need the wiring diagram that is all things i need"

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.
We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.
Hope this will be of help to someone somewhere.
Best regards

Ok guys check this out.I ran out of petrol(ok I am a girl!) and the yellow engine light stayed on afterwards.Hyundai said I would have to sell my soul to get it sorted but would be ok to run I t failed it's Mot on emission,but the local garage managed to temporarily fix the problem to get it through.The light came back on after wards-!!! So I did some research on Internet and here's how to reset it yourself-- Take off positive lead from battery,then turn ignition key on to get rid of any stored power.Then pump the footbrake(yeah I wondered why!) for about 20 secs.You will hear allsorts of clicking in the engine as ecu resets.Then reconnect battery lead!! Wallah !!!!
I went armed with this knowledge to the local garage(much to their amusement) and asked if they could reset the ecu,and they said a dealer would have to do it.I said well I know how and asked them to disconnect battery for me(their frowns got deeper by the minute).The rest I did in front of them,They were gobsmacked!!!!
They were amazed and asked me to call in a few days to tell them if it had worked permanent as they had learned something----so far so good!!!!
I f you have a computorised radio make sure you know the reset code for that as it may knock it off.
The ecu resets when you drive away.Now drives like a dream.
