Siemens (Continental) 904 — after a calibration edit the checksum must be recalculated.
This unit is found on дизельных vehicles International (2006–2013) — a total of 13 models, among them International 3000 Re, International 3300 Ce, International 4100 Series, International 4200 Series, International 4300 Series, International 7300 Series.
Recalculation is needed after any calibration edit — Stage 1, Stage 2, DPF off, EGR off, AdBlue/SCR off, DTC removal, Flap off, Lambda off, Speed limiter off, Torque monitor off, Hot 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.
