CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE

id094000103200

• 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
  ― Engine off natural vacuum (Engine-off-natural-vacuum is integrated in the PCM)
  ― TCM
  ― DSC/RSC HU/CM
  ― BCM
  ― 4WD control module
  ― Keyless control module
  ― PLG control module
  ― BSM control module (RH)
  ― BSM control module (LH)
  ― Position memory control module
  ― SAS control module
  ― Theft-deterrent control module
  ― Forward sensing camera
  ― Instrument cluster
  ― Audio unit
  ― Audio amplifier
  ― 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.
