B127E MeaningThe infotainment display and controls are a separate component from the radio, combined into an assembly. The assembly is supplied battery voltage and ground from the vehicle harness. The Human Machine Interface Control Module communicates digital video data for on-screen display through a dedicated cable containing the LVDS data circuits.
Control information, touch communications and dimming level for the display are communicated via a LIN serial data circuit to the Human Machine Interface Control Module.
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 Diagnostic Trouble Code (DTC).
