CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE
NG: CAN SYSTEM
• 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
— DSC/RSC HU/CM
— BCM
— AWD control module
— PLG control module
— SAS control module
— Keyless control module
— Instrument cluster
— Audio unit (base module)
— Audio amplifier
— RES unit
— Hands-free telephone unit
— Information display
— Engine off natural vacuum (Engine-off-natural-vacuum is integrated in the PCM)
• 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.
