Was bedeutet der Fehlercode?

Every time the engine control module (ECM) starts up, the stored checksum of its software is compared with a calculated one. If they differ, this code is set, which happens when the software has been changed, for example after an optimisation, or when it is corrupted. If the software was changed on purpose, the code does not need to be acted on.

Mögliche Ursachen

The engine control module software has been changed
Invalid internal checksum in the engine control module software

Was Sie tun können

1If the engine control module has had modified software, for example an optimisation, that explains the code and it needs no action
2Tell the workshop that the software has been modified so that it is not overwritten by mistake during a software download
3If the software has not been changed on purpose, have a workshop download new software to the engine control module
