CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE


id094000101300

•  Due to the simplification of the wiring harness, a CAN system for transmission of multiplex input/output signals among electrical modules has been adopted.
•  Twisted-pair wiring is used for connections between the following modules. (Each electrical module hereafter referred to as a CAN system-related module):
―  PCM
―  TCM (ATX only)
―  DSC HU/CM
―  4WD control module
―  SAS control module
―  BCM
―  Keyless control module (with advanced keyless)
―  Instrument cluster
―  Audio amplifier (with Bose®)
―  Climate control unit (with full-auto air conditioner)
―  Audio unit (base module)
―  Information display
•  With an on-board diagnostic function included for each multiplex module, display of DTCs using the Mazda Modular Diagnostic System (M-MDS) has improved serviceability.
