Engine Control Module (ECM)

The ECM provides information over the serial data circuit to the generator battery control module. The generator battery control module monitors the following data parameters provided by the ECM:

• Intake air temperature
• Fuel grams per second
• Throttle position
• Engine cooling fan speed
• Engine coolant temperature
• Exterior Environment - Outside Air Temperature

The generator battery control module uses these data parameters for different charging system modes depending on the required voltage needed.
