CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE

id094000101300
• 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 (FS5A-EL, JA5AX-EL)
  - 4WD control module
  - DSC HU/CM (with DSC)
  - ABS (ABS/TCS) HU/CM (with ABS (ABS/TCS))
  - Keyless control module (with advanced keyless system)
  - Instrument cluster
  - Audio unit (base module)

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