Five Hundred AWD V6-3.0L VIN 1 (2005)
N17-N21
Normal Operation
The medium speed CAN has an unshielded twisted pair cable, circuits 2180 (WH/BK) and 2181 (BK/YE). The audio unit, the driver seat module
(DSM) (if equipped), the dual automatic temperature control (DATC) module (if equipped), the digital versatile disc (DVD) player (if equipped), the
instrument cluster, and the smart junction box (SJB) are all on the medium speed CAN. The medium speed CAN remains operational with the
severing of one of the medium speed CAN circuits or if the data minus circuit is shorted to ground. Communication may also continue if one of the
termination resistors is lost. The medium speed CAN does not remain operational if the data plus circuit is shorted to ground or shorted to voltage.
The medium speed CAN also does not remain operational if the data minus circuit is shorted to voltage. The total resistance values must not be more
than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the medium speed CAN circuits, damage to the data link connector
