The best way for a deduction to be made is by making sure that all the sensors and actuators are functioning properly; we need to ensure that the sensors are supplying the correct amount of power to the ECM and that all components are able to receive the correct signals that the computer provides. ECM Motor Testing. When you get a reading that is equal to 1.7 times the power supply, that means the motor is working properly. Under the TradeFox brand, Supco helped bring their\r inventions to life through additional engineering and manufacturing. The electrical motors that were used in HVAC applications were AC induction style motors that were either single-or multi-speed they'd run at one speed for heating, another for cooling, and sometimes a third speed for two-stage systems. Put the multimeters positive lead to the battery ground post, and then you need to touch the multimeters positive lead fleetingly to the proper terminal of the modules harness connector.
How To Test Your ECM Computer - Flagship One Blog No matter what you do to your engine control unit (ECU), whether you reflash your car ECU or test the ECU with a multimeter, you have to conduct a visual inspection around the ECU computer.
