Can Communication Signal Chart

Refer to HOW TO USE CAN COMMUNICATION SIGNAL CHART for how to use CAN communication signal chart.

NOTE:

Refer to ABBREVIATION LIST for the abbreviations of the connecting units.
CAN data of the air bag diagnosis sensor unit is not used by usual service work, thus it is omitted.
The AV control unit uses CAN communication only for communicating with the diagnostic tool (not with other connected control units).
