Caterpillar has frequently been asked about the possibilities of the engine Electronic Control Module (ECM) becoming corrupted by computer viruses that are introduced though PC based service tools such as Electronic Technician (ET).
A review of the ECM FLASH file process and PC virus attachment methods has been conducted to identify the potential risks and possible effects associated with servicing Caterpillar product with virus infected PC service tools. The review has concluded that with the ECM FLASH file encryption process, there is virtually no risk of an infected software FLASH file being executed by an ECM.
If an ECM FLASH file was infected prior to installation, the ECM would identify the new FLASH file as containing errors and would not execute the installed software. If the PC service tool were infected and resulted in FLASH file corruption during installation, the ECM would again identify the corrupted file and would not execute the infected software.
