Introduction
Over the next three model years, all Lexus vehicles will begin using an all-new diagnostic communication protocol, Controller Area Network (CAN). CAN will be introduced on the 2004 LS 430 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.
- 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.
