Lights On Indicator
WARNING: This page is about a different car, the 2015 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When the parking lamps are turned on, the BCM sends the parklamp status message to the GWM over the High Speed Controller Area Network 1 (HS1-CAN). The IPC receives the parklamp status message from the GWM over the High Speed Controller Area Network 3 (HS3-CAN) to illuminate the lights on indicator.
