Error due to
receipt of an
unexpected
message
01F3 Error due to receipt
of an unexpected
message while ac-
knowledging a diag-
nostic message.
The device firmware
handles this diag-
nostic message with
the highest priority.
Only when this mes-
sage has been ac-
knowledged cor-
rectly are other
errors indicated (if
present).

ment process,

dicated.
Check and adapt the
assignment of the di-
agnostic and confir-
mation variables at
the DEVICE_STATE

nostic message
