Volvo G930 no start

[barkoguru]

Owner stated that his 2007 G930 died when he bottomed a cylinder out while at idle, basically he pulled the lever to raise his blade and it was already up and being at idle it immediately killed the engine, it hasn’t started since, changed filters etc and nothing, says when he turns the key on he gets a red question mark with a triangle and two yellows, I haven’t seen the machine yet so any ideas will be appreciated.

Is the valve stuck and not returning to the center position? If it's stuck still trying to lift will make the engine not start. It's like having the aux. hyd's engaged. Engine won't start under load. Don't know if that would cause the lights on the dash though.

No the display is saying computer failure, the photo below is the connector on the ecm, there was a large amount of green corrosion across the two 24v pins that powder the ecm, even after trying to clean the connection the ecm still doesn’t power up, I’m currently looking for a replacement plug and or replacement pins.

Anyone have a wiring diagram of the ecm wiring harnesses ?
