Interchangeable Part Numbers:

This PCM is 100% compatible with and supersedes PCMs bearing any of the following Part Numbers:

Firmware Revisions: 16265035, 16263494

Hardware Codes: 16263494

Hollander Part Number: 590-05454

The Hardware Code is a number assigned to an PCM 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 PCM. 

Part Number Notes: 

  1. The last two alpha characters in PCM Part Numbers refer to the firmware revision. We will ship you the latest revision which is backward-compatible with all prior revisions.
  2. 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 PCM with or without a leading zero.
  3. Your old PCM 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.

MAK’s stands behind everything we sell and you are always just a free phone call away from a live expert who knows PCMs!
