Questions about this file
Is this original file compatible with my Caterpillar 320D?
Compare the hardware number (2781151-00) and the software number (3317539-00) with the identification your tool reads from the ECU. The software number must match; a different hardware revision usually means a different file. Caterpillar ADEM 3/4 modules are identified by the part number on the module and the flash file (software) part number visible in Cat ET.
