EEPROM Programming Procedure

NOTE: Refer to latest Isuzu Technical Communication System (ITCS) information for reprogramming or flashing procedures. Programming PCM/EEPROM requires the use of a scan tool and special manufacturer equipment.

Connect TECH 2 scan tool to DLC and retrieve program information from PCM. Ensure that battery is fully charged. Turn ignition on. Ensure that Vehicle Interface Module cable connection is securely connected to DLC. Follow scan tool instructions to program EEPROM using latest software available from ITCS. If PCM fails to program, recheck PCM connections. Ensure that most recent ITCS information is being used. Attempt to program PCM. If it still can not be programmed properly, replace PCM. Reprogram new PCM, then perform ON-BOARD DIAGNOSTIC II SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. Start engine and run for one minute. Use scan tool to check for any stored DTCs.
