BULLETIN
September 8, 2003
Over the next four model years, all Toyota vehicles will begin using an all±new diagnostic
communication protocol, Controller Area Network (CAN). CAN will be introduced on the
2004 Prius this fall. A CAN Interface Module has been distributed to all dealers as an
essential Special Service Tool (SST) and will allow the Diagnostic Tester to communicate
with CAN±equipped vehicles. Please use the following instructions to install the new CAN
Interface Module as soon as it arrives at your dealership.
NOTE:
Version 10.2a or later Diagnostic Tester Software must be used to enable
communication with CAN±equipped vehicles. Version 10.2a will be distributed to
dealers via TIS before CAN±equipped vehicles arrive at dealers.
There is no need to remove the CAN Interface Module when working with non±CAN
systems or older software versions (Version 10.1a or earlier). The Diagnostic Tester
will communicate with all DLC3/J1962 based systems with the CAN Interface
Module installed.
