Accessory Power Gauge
WARNING: This page is about a different car, the 2016 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The accessory power gauge, displayed in the LH display screen, is a virtual gauge that displays the amount of energy being used for the climate control system and other accessories. The IPC utilizes power usage information from the PCM for the climate control system and other accessories that are placing a demand on the overall electrical system and using battery energy.
The IPC receives the climate control power usage data and the accessory power usage data from the GWM over the HS-CAN3. The GWM receives the power usage information from the SOBDMC over the High Speed Controller Area Network 1 (HS1-CAN).
