see the wires from the cabin - from the plugs on the left when viewed from the front of the cabin. check fuses and wiring from the cockpit to the engine ECU.
I found someone with the same problem.
and finally being found that the driver controlled the braid on the left (front) is damaged to the chest and a broken wire

MAN with EDC7 or MS6.1?

Check up on the big connector (connector "A") a supply "+30" pin 1,7,12,13 and "-31" (mass) pin 3,9,14,15
On the connector "B" pin 36 check signal "+15" ignition. If power and signal is OK, EDC is dead. You can check on a desk by connecting EDC7 through ampermeter. Following the filing of terminal "+15" , EDC7 must "wake up" and consume approximately 200 mA , and go to "stand by" after few seconds after removal of the terminal "+15"
I am sorry for my English.

PS The experience - through connector "C" inside the unit gets oil and water.
