Updated software is available for the engine Electronic Control Module (ECM) for the above listed engines. This software contains several new features and several improvements to existing strategies.Refer to one of the cross-references for flash files that are published in the Service Information System (SIS) or the FIND system in order to determine the correct numbers for flash files that are for a particular engine. To use the FIND system, type "FLASH" in the "Search Document Types" field. Then type "3500B" in the "Key Word/Phrase" field. This search should return the following documents:
3500B Commercial Engine (Built > 4/97) FLASH File Cross-Reference
3500B Commercial Engine (Built < 4/97) FLASH File Cross-Reference
3500 With EUI Option Commercial Engine FLASH File Cross-Reference
3500B HD (High Displacement) Commercial Engine FLASH File Cross-Reference
3500B Machine Engine FLASH File Cross-ReferenceUse the appropriate document to look up the flash file for a particular engine.In the SIS, all the above cross-references for flash files are grouped into a single file that is called "readxref.txt". You can download this file and you can open this file with a word processor.The cross-references for the flash files will be updated as files become available. The FIND system has the most current information. The SIS is updated periodically with information from the FIND system. Currently, the "FLASH File Part Number Progression" application in the TMI system does not provide accurate data for 3500 Engines.SOFTWARE CHANGES
Software Changes
All of the following changes are included in the software for engines that were built after April 1997 that contain the D version of the electronics. Only the "Low Coolant Temperature Warning" change was added to the software for the engines that were built prior to April 1997 that contain the C version of the electronics. The 3.2 version or a latter version of the Cat ET is required to access some of the new parameters for this software.Diagnostics Indicate An Incorrect Signal From A Fuel Pressure Sensor
The above listed engines may log "94-02 and/or 289-02 An Incorrect Signal from a Fuel Pressure Sensor" diagnostic codes mistakenly. A previous software release disabled these diagnostics when engine speed was less than 200 RPM. The previous software release reduced the problem, but the software release did not eliminate the problem.This strategy has been improved in order to eliminate the false logging. The trip point for the diagnostic codes has been changed from 15 kPa (2 psi) differential pressure to 70 kPa (10 psi). This change will help prevent the incorrect fault logging, but this change will delay the notification of an "Incorrect Signal from a Fuel Pressure Sensor" problem until the differential pressure exceeds 70 kPa (10 psi).In addition, the absolute value of the fuel filter differential pressure
