Rear Seat Entertainment Module
RSE Module
The Rear Seat Entertainment (RSE) module is located in the rear right-hand (RH) side of the luggage compartment. The RSE module interfaces between the audio and video inputs from other systems components and the video display and audio outputs.
The RSE module communicates with the audio systems via a MOST connection. Audio output from the digital versatile disc (DVD) autochanger and the AVIO panel is processed by the module and passed on the MOST ring to the audio amplifier to allow audio output to be played on the vehicle speakers or on the cordless headphones.
Video input from the TV tuner, digital versatile disc (DVD) autochanger and the AVIO panel is also processed by the module and passed to the two RSE liquid crystal display (LCD) screens and the TAD on separate video connections. The RSE module also controls the power supplies to the RSE liquid crystal display (LCD) screens and relays the infrared remote control signals received by the RSE liquid crystal display (LCD) screen infrared sensors to the digital versatile disc (DVD) autochanger. The infrared signals are passed from the RSE liquid crystal display (LCD) screens to the RSE module on a bus system known as the IS bus.
The digital versatile disc (DVD) autochanger outputs some of its information to the RSE module on an Alpine proprietary bus known as the Ai Net.
The RSE module has two modes of operation; engine running mode and reduced operation mode. With the engine running the RSE module has full functionality. When the engine is not running the RSE module has reduced functionality to prevent excessive drain on the vehicle battery. The reduced functionality comprises a reduced audio volume and time limit on system operation.
The reduced audio volume is only active when the engine is not running. The audio volume is limited to a maximum setting of 12 to reduce battery consumption. If the volume was set at a higher level than this when the engine was running, when the engine is subsequently started, the volume level will gradually increase to the previously selected setting. This prevents the user being distracted by a sudden increase in volume.
The time limit operation is active when the key is removed from the ignition and the system is manually switched on using the TAD. The system will operate for a maximum of one hour. The battery voltage is continually monitored by the IHU. If the IHU detects that the battery voltage has fallen below a predetermined level, the IHU will shut the infotainment system down to prevent further battery drain. Once the system has shut down due to low battery voltage, it can only be restarted when the engine is running and the battery voltage has risen above the threshold level for more than one minute.
The module is connected into the infotainment system with five harness connectors.
