Concorde V6-2.7L VIN R (1998)
Body Control Module: Description and Operation
Audio System
There are three radio systems available that communicate on the PCI bus. They are RBR, RBN, and RAZ models. They use the bus for two reasons. First
is to communicate trouble codes to the body control module, the second is for use with the driver memory selection system. The radio stores two sets of
station presets and can be recalled by pressing the optional memory select button (located on the drivers door). The RBR will have 6 speakers and a 120
watt external amplifier. The RBN will have 7 speakers and a 240 watt external amplifier. The RAZ will have 9 speakers and a 320 watt external
amplifier. Depending on the manufacturer, some systems have a Front/Rear channel system and others have a Left/Right channel system.
