CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE

id094000101300

• Due to the simplification of the wiring harness, a controller area network (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 to EPS control module to ABS HU/CM to instrument cluster

• With an on-board diagnostic function included for each multiplex module, display of DTCs using the WDS or equivalent has improved serviceability.
