Error indication is reported if the steering wheel disengage ability check (if enabled) has failed. This means that too
much time has passed since a steering wheel position change has last exceeded the defined position change
threshold. Both the position change threshold and the timeout value can be configured as required by the
application.
To allow removable set-point controllers to be used, vehicle specific data can be stored in the PVED-CL's
configuration memory. For further details refer to PVED-CL User Manual, 11079550.

Diagnostics

Although PVED-CL supports J1939 diagnostic protocol [J1939-73], there exists a proprietary way of
informing about errors. The configuration/diagnostic tool has an access to the event logs maintained by
PVED-CL's software, which is intended to make the debugging easier as well as to help an OEM or a
support team to tune the system. Detailed information about the interface is provided in the chapter
Diagnostics (proprietary) on page 35.
