Actuator failure being caused by bad de-mandate tune?

[Mr Hagg]

Could be a few things for sure bad tuning cause bad turbo. However we find many times theres a issue on the def side with a sensor or something or even bad wiring and just so happens that the j1939 data link to turbo and def tank are the same line. the terminal resistor is on the def tank. Thus if there is any issues there it will cause the tubo to act up. Many times if the code is not blocked it will throw a turbo code for abnormal update rate. when we see that we just relocate the terminal resistor up to the line for the turbo and remove the line going back to def tank.... You can check that with turbo plugged in and back prob the connector to the turbo it should be 12 volts on one pair or wires and 60 ohms on the other set....unplugged the turbo will read 120 ohms and the plug to truck 120 ohms
