Hello guys

I have a problem with this as most off my diagnostic kit has been sent away for repair & what i have got wouldn't go into this so I had to borrow another garages.Recovered vehicle after it shuddered to a stop, first checked cam-belts (as I had fitted them less than a year ago) all ok so started engine. It wouldn't rev & smoked badly. Found intake butterfly was being sucked shut so removed vacuum pipe. It then ran reasonably well. Also found rev counter not working but had revs showing on scanner. Tried another crank sensor with no difference. I think the rev counter is running from the diesel pump but can't find a wiring diagram. I may be wrong but i think the ecu is seeing a problem with the fuel pump and shutting the engine power down by closing the intake flap. Any suggestions welcome,

Alan

I have access to "toleranc data" and there is a basic pump diagram there but I cant see any reference to the rpm signal. These L200 do suffer from the vacuum side with pipes dropping off and perishing. There is a couple of EGR solenoids near the throttle body and in my experience thats area where the pipes give problems, they are not all easy to see so pull the pipes about.

Just an update on this one. The customer was working abroad so this ended up in that dark corner of the workshop. I managed to get hold of a mitsubishi manual on disc with all the test procedures which was brilliant. I couldn't find anyone to test this ecu so eventually bit the bullet & brought a second hand unit/immobiliser unit/ key & lock set. It started & ran perfectly

Were did you get the disc, we have one with no communication with all controllers apart from the airbag.

Thanks Martin.

Martin/Alan,
what is it with these L200's? I have one at the moment with a code 46, injector adjustment valve, but am having trouble finding detailed information to test the system. If you can point me in the right direction, Alan, it would be greatly appreciated,
TIA,
Peter

Hello Martin & Peter, I got the disc from ebay, I can't find the seller I got it from but if you search "L200 manual" loads come up. Also Peter, look at the known faults on autodata, I think code 46 is there but wasn't the fault on mine.
p.s. If you send me your postal address i'll send you some info
