Acyclic extended diagnostics (general fault codes)
In addition to the extended diagnostics available by cyclic data exchange (shown above), further
extended diagnostics are available via acyclic communications. This consists of six bytes. See
Diagnosis reply (available cyclically) (Page 237
) for information on the location of the
Extended
Diagnostics.
Note
Certain fault codes (identified by an asterisk [*] in the tab
le below) will persist until a manual
reset has been performed [see Fault Reset (3.2.)
].
