Program update function
This function allows you to update the engine ECM program
to the latest version using a reprogram-
ming harness (VPP harness).
Writing function of engine serial numbers
A new function enables you to write an engine serial number to a new, replacement part engine ECM
(sup
plied by the Part Division). With this new function, it will be possible to reprogram engine ECMs that
are supplied as replacement parts by communicating with YMAN.
