    A 611 153 11 91 / 0 281 011 747 - bosch ecu

    Hi everyone, does anyone have a schematic for the A 611 153 11 91 [Mercedes part number] / 0 281 011 747 [BOSCH part number] ECU, or know what signals go to the damaged pins of the connector?

    You should be able to get a service technician manual and look for that area to be able to know what pins are affected by this burn out area

    One note these manuals are not cheap but you have to go to the dealership to get them

    Sometimes you can get just the electrical wiring diagrams from the dealership for free or for a fee at least in this country

      I already have access to the car's electrical wiring as I used to work as a mechatic at Bosch. The pins are for the crankshaft, camshaft and the common rail pressure sensor if I remember correctly.
      I was looking for the ECU's schematic because the signal lines are untraecable as they're routed on an internal layer and I wanted to solder a jumper wire to the connector to restore the damaged connection.

        If this board is more than 2 layers it will be very difficult to almost impossible to repair at least this has been my experience
