Circuit/System Description

The infotainment system Info Display Module is supplied battery voltage and ground . The Human Machine Interface Control Module communicates with the info display via a dedicated cable for the LVDS data circuits. All video information to the display, as well as backlighting dimming level, and screen touch signals, are communicated over the LVDS data circuits.

If the Human Machine Interface Control Module detects the display is not responding to the output on the LVDS circuits, the Human Machine Interface Control Module sets the DTC.
