Code B127E 2016 Chevrolet Silverado Description

The infotainment display and controls are separate components from the radio, combined into an assembly. The assembly is supplied with battery voltage and ground from the vehicle harness. The Human Machine Interface Control Module communicates digital video data for an on-screen display through a dedicated cable containing the Low Voltage Differential Signaling (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).
