   CM849B ECM/ECU/PCM 2006 Dodge RAM 2500/3500 HD 5.9 L Cummins Rebuilt OEM 4931975 About Us Founded in 2015 by self-taught mechanic Mak Cabessa, our company began at a kitchen table with a passion for repairing and reselling automotive parts. After discovering a widespread need for reliable replacements of the Totally Integrated Power Module (TIPM) in Chrysler, Dodge, Jeep, and Ram vehicles, we focused our efforts on restoring these hard-to-find components. Since then, we’ve grown into a multi-location operation with warehouses in California and support teams in the Philippines. Today, we offer a range of rebuilt OEM parts—including TIPMs and ECMs—helping thousands of customers get back on the road with affordable, dependable solutions backed by hands-on expertise.

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. 02 The last two alpha characters in Automatic\|Manual Part Numbers refer to the firmware revision. We will ship you the latest revision which is backward-compatible with all prior revisions. 03 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 Automatic\|Manual with or without a leading zero. 04 Your old Automatic\|Manual 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. WHY CHOOSE MAKS MODULES?
