Diagnostic Tool Set - Software Communication Problem

REFERENCE: SPECIAL SERVICE TOOLS

NO.: SSOO1-96

DATE: AUGUST 30, 1996

MODEL: ES 300

VERSION 3.1 DIAGNOSTIC TOOL SET SOFTWARE COMMUNICATION PROBLEM WITH 1997 ES 300





Due to a change in communication standard for the 1997 ES 300, the Version 3.1 Diagnostic Tool Set Software will display the error message below when the technician attempts to use the ALL DATA list or the ACTIVE TEST functions in ENHANCED OBD II.

This problem will be corrected with the release of 1997 Model Year software in November. Until then, there are two alternatives for diagnosing the ES 300 with the current Version 3.1 software:

1. ENHANCED OBD II

^ USER DATA list (less than 50 data lines)

^ Specialized data list from SELECT DATA menu (MISFIRE, O2 SENSOR, EGR, etc.)

2. CARB OBD II

^ All CARB OBD II functions work normally.
