MULTIPLEX COMMUNICATION SYSTEM OUTLINE

id094000000100

• 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 ABS (ABS/TCS or DSC) HU/CM to instrument cluster

- Instrument cluster to audio unit

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