Engine Control Module (ECM): Notes
WARNING: This page is about a different car, the 2008 Isuzu i-370, 2008 Isuzu i-290, 2008 GMC Canyon, and 2008 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
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.
