    Re: DAG3DCMBCC0 REV C cpu shorted?

    Well I removed the mosfet in black color and now cpu have normal values now
    In ohm mode shows 1 ohm but still the same problem
    Is the cpu fried?

      so
      i replaced the mosfet that was shorted and now diode mode measurement is normal but the same problem exists


      what can measure at this point
      is the cpu fried for the main problem

      when i turn on theres no voltage in the coils of cpu

        Hi!dag DAG3DCMBCCO-REC:C MODELGEDC short circuit, I can't find it. Where can I find the schematic?

          The current CPU resistance value is very small. You are not sure that the CPU is protected due to short circuit. You can use an oscilloscope to measure whether there is a PWM waveform at the front end of the CPU inductance. I think the probability of PCH failure is higher.
