This circuit sends an operation signal from the steering pad switch to the radio receiver.

If there is an open in the circuit, the audio system cannot be operated using the steering pad switch.

If there is a short in the circuit, the same condition as that when the switch is continuously depressed occurs.

Therefore, the radio receiver cannot be operated using the steering pad switch, and also the radio receiver itself cannot function.

The sound signal that has been amplified by the stereo component amplifier is sent to the speakers from the stereo component amplifier through this circuit.

If there is a short in this circuit, the stereo component amplifier detects it and stops output to the speakers. Thus, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier or speakers.

SYSTEM DESCRIPTION

  1. OUTLINE As a unique feature of the Rear Seat Entertainment (RSE) system, the front and rear seat occupants can enjoy different audio-visual modes at the same time. Thus, this system offers enhanced entertainment to the rear seat occupants. The rear seat occupants can control the audio-visual modes with the remote controller (switch assembly), and listen to the audio using wired or wireless headphones. The RSE system is controlled by the television display assembly, and the communication between the audio head unit or multi-display and the television display assembly is established via an AVC-LAN (Audio Visual Communication-Local Area Network). The RSE system can play discs recorded entirely in the MP3 format, as well as music discs containing a mixture of CD data (CD-DA files) and MP3 data. HINT: MP3 is short for MPEG1 (Moving Picture Expert Group Phase 1) & 2 Audio Layer 3. It is an audio compression standard set by a working group (MPEG) of the ISO (International Standards Organization). MP3 is able to compress audio data to about 1/10 the level of a conventional disc.
