Hey guys, so I have a problem with F12 650i , today I've washed the car , drove it back to garage , wiped it out and went home , after I came back I wanted to go to shop and ... car cranks but won't start . 

First one of ECUs wasn't responding in ista (no communication) then I unplugged battery and plugged back , ECU showed up in ista , car cranked and started and immediately died . Now it has error : 

113026- Ignition relay and injectors ,supply voltage, fuel injection, short circuit to ground 

It's the only one error that's show up , I've checked the fuses on ICM but everything is fine . 

Any ideas ?

Disconnect injector plugs one by one maybe one of the injectors is shorted to ground. Did you wash the engine?

No I didn't , just normal car wash . That's it

Have you worked thru the testmodule for that fault in Ista? If yes, what Ista gives for possible fault?

It opens me like 6 wiring diagrams , and everything goes to ISM relays which are good .

DME tells you it does not get 12V from relay (well, it says short to ground, but that is just it's way to say that it thinks there's 0V). So not much to test - fuses F07, F08, F09, F010 and pins 4 & 10 on DMEs. Is there 12V on those pins?

---

P.S. If it really distinguishes between injection and ignition in the fault then fuses F08 & F09 and pins 10. But it's not hard to check all just in case.

P.P.S. OK, I assumed N63N engine with 2 DMEs. If not, then just F01 and pin 1.

Yes this is N63 with 2 DME , water cooled type . Yes there is 12V on those pins , where those Fuses are ? under the hood passenger side there is ISM with fuses and relays soldered to the PCB , but its ok . Relays working (clicking while 12V applied) and fuses are ok .
