Siemens (Continental) MCM2.1 — after a calibration edit the checksum must be recalculated.
This unit is found on дизельных vehicles BharatBenz, Claas, Mercedes Trucks, Setra, Vervaet, Western Star (2003–2022) — a total of 21 models, among them BharatBenz HDT C, Claas Jaguar, Mercedes Trucks Actros, Setra S415 UL, Vervaet Beet Eater, Western Star 4700 Series.
Recalculation is needed after any calibration edit — Stage 1 truck, AdBlue off, DPF off, EGR off, Limiter speed/RPM, DTC removal, Cold-start fix: the checksum no longer matches, and the ECU throws an error or refuses the firmware.
Upload the modified file (MOD) and the original (ORI) — the tool compares them, finds the affected regions and recalculates only the required checksums, leaving the rest of the calibration untouched. The result is ready in a second and free; downloading the fixed .bin requires registration in the portal.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
