CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE

• Due to the adoption of the power retractable hardtop control module, the CAN system has been changed.

• 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 (AT)

- DSC HU/CM (with DSC)

- ABS HU/CM (with ABS)

- Keyless control module (with advanced keyless system)

- Steering angle sensor (with DSC)

- Instrument cluster

- Power retractable hardtop control module (with power retractable hardtop)

• 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.
