Hi,
I have an ECM from Cummins ISX CM570, PN. 3408426 which has an internal issue with the Fan Clutch output at pin number 5 in Actuator connectors. Fan clutch status parameter change as expected when is manually activated or by coolant temperature but there is no electrical output.
I've tested with other ECM and same configuration getting success, so the issue is the ECM under question. Does anyone have information about the mosfet location in the circuit board. I opened the ECM but there are many drivers, maybe injectors and engine brake, but I'm not familiar with the location of each component.
Thanks for your support.
