Questions about this file
Is this original file compatible with my Peterbilt MODEL 387?
Compare the hardware number (3684275) and the software number (AV10217.10) with the identification your tool reads from the ECU. The software number must match; a different hardware revision usually means a different file. Motorola CM controllers (Cummins, DAF PACCAR, Scania EMS) are identified by the CM model and a calibration/ECM code; many are read via the diagnostic connector with the engine harness powered.
What exactly do I receive when I buy the Motorola CM871 original for €25?
An unmodified factory read of the Motorola CM871 (HW 3684275, SW AV10217.10) as stored in our archive — a binary file in the format produced by the original reading tool. No modifications, no checksum changes: it is meant to restore the ECU to its stock calibration or to serve as a reference for a tuning job.
How and when is the file delivered?
After payment we confirm the read matches the numbers on this page and release it to your account, with an email notification — usually within 3 hours, within 24 hours on business days. If your ECU reports different numbers, tell us with the order and we look for the right file before delivering anything.
Can you also tune this Motorola CM871 or remove EGR / AdBlue / DPF?
Yes — upload your own read through the tuning service and choose the modifications; every tuning job is quoted individually before you pay. The original on this page is useful as a backup before any modification is flashed.
