Engine Control Module (ECM)/Powertrain Control Module (PCM)

The ECM/PCM provides information over the class 2 serial data circuit to the generator battery control module. The generator battery control module monitors the following data parameters provided by the ECM/PCM:

• 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.
