Audio Remote-HFL Switch: Notes

The audio remote switch and the HFL switch are integrated to the audio remote-HFL switch that uses the digital communication (LIN).

When using any button or the selector wheel on the audio remote-HFL switch, the control signal is sent to the audio unit via the gauge control module. The gauge control module reflects the control information of the audio remote-HFL switch as indication to the multi-information display (MID).

If the LIN circuit is open or shorted between the gauge control module and the audio remote-HFL switch, the gauge control module detects the related DTC.
