Cummins CM850 — the older generation in trucks and machinery
CM850 is an older Cummins engine controller, and it is supported for files read with Calterm. This catalogue indexes 49 software versions, most of them from 2006 to 2018.
It shows up in a wide mix: DAF CF, LF45 and LF55 trucks, Komatsu WA470 loaders, PC800 excavators and D155AX dozers, JCB, Nissan Atleon, International and Kenworth trucks, King Long buses and the New Holland T8040 tractor. Engines range from the 4.5 L and 6.7 L up to the 15.2 L and 23.2 L.
Files read with Calterm are modified, checksums are recalculated and the file comes back in XCAL format, ready to write back with Calterm.
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 CM850
Can I send a CM850 file read with Calterm?
Yes — it comes back in XCAL format with checksums recalculated, ready to write back with Calterm.
Can I remove only the DPF and keep AdBlue/DEF?
We do not recommend removing only the DPF while AdBlue/DEF keeps working: the SCR side will keep logging faults. AdBlue/DEF can be removed on its own while the DPF stays in service.
