Motorola/Cummins MCM21 — Mercedes MCM on Mercedes and Freightliner
This page lists the Mercedes MCM engine controller under the spelling “Motorola/Cummins MCM21”, as it is written in the source database: 2 software versions from 2019 to 2024 — Mercedes Actros-1851, Freightliner SD122, with the 12.8 L.
The MCM is the Continental engine controller of the Mercedes-Benz Euro 6 engines — the OM93x 5.1–7.7 L and OM47x 10.7–15.6 L — and of their Detroit DD5, DD13, DD15 and DD16 versions; the ACM next to it runs AdBlue and holds all the DOC/DPF maps. We have worked with MCM/ACM since 2017. The complete route is to read both the MCM and the ACM; reading only the MCM and unplugging the ACM also works, but the vehicle then needs Xentry coding, and we send the instructions.
Every software version below has its own page with the vehicle it belongs to, the solutions available for that exact file and a price calculator. Read the ECU, find your number, open the page.

Questions about Motorola/Cummins MCM21
Do I need to read the ACM as well?
The complete route is to read both the MCM and the ACM. Reading only the MCM and unplugging the ACM also works, but the vehicle then needs Xentry coding afterwards, and we send the instructions.
