Errors: messages and removal
Depending on the error type, errors that are diagnosed are displayed via the local
diagnostic indicators and/or transmitted to the controller as diagnostic messages.
The tables below provide an overview of the diagnosed errors, their causes, effects, and
possible measures for error removal.
In this manual, diagnostic codes are sorted in ascending order by error type. The following
errors are possible:

error is then acknowledged. Errors that must be acknowledged are indicated in the
“Acknowledgment” column in the tables below.
