Hardware Codes: 04727040AA, P04727040AA
The Hardware Code is a number assigned to an ECM during initial manufacturing. It is the “platform” onto which firmware specific to your vehicle / powertrain is then loaded. Always seek to purchase the latest Firmware Revision of your original ECM.
Part Number Notes:
- The last two alpha characters in ECM Part Numbers refer to the firmware revision. We will ship you the latest revision which is backward-compatible with all prior revisions.
- The presence or absence of a leading zero as the first character in the part number is not significant. It may appear on your old ECM with or without a leading zero.
- Your old ECM may show a “P”, or “P/N” in front of the part number. This is merely a field heading on the sticker that means “Part Number” and is not significant.
