Diagnostic Instructions
DTC Descriptor
Front Video Display Output Signal – General failure
Front Video Display Output Signal – Short to ground or open
Circuit/System Description
The 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 radio 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 radio.
If the radio detects the display is not responding to the output on the LVDS circuits, the radio sets the DTC.
Diagnostic Aids
Malfunctions may include a flickering or distorted image or a blank screen.
A momentary spike in volume upon start up may be due to the radio accessing the guest profile before switching to an established customer user profile. The radio will remember the set volume level the last time it was shut down in the guest profile mode, which is a normal operating characteristic. To alleviate the issues turn the radio on and proceed to the guest profile. Turn the volume level down to a lower level and power down the vehicle, the radio will retain the lower volume level upon the next start up.
