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.
