Showing of the latest error codes and alarms
To be able to access the showing of inactive errors, the engine
must be turned off. Inactive warning and errors are shown inverted
relative to the display setting. If inverted display already has been
selected, the inactive errors will be shown in the standard display
mode.
The ten last shown alarms / error codes, which then have become
inactive, are to be saved on the list.
It the inactive alarms / error codes are shown in reversed
chronological order as they were shown to the operator.
A condition for an alarm / error code to take up a new position in
the list is that it has not been stored previously during the same
24 hours.
Alarm screens
The alarm screen will be shown as long as the error remains.
If amber central warning lights up when the alarm display is shown,
the cause must be investigated at the next stop. The alarm will be
repeated next time the engine is started, if it still is active.
Acknowledgement of the alarm is done with the select/
acknowledge key.
If red central warning flashes when the alarm screen is shown, the
machine should be stopped and the cause investigated
immediately. Values may be checked by using the respective
component keys on the keyboard, but the alarm screen returns ten
seconds after the last pressing of a key. When required, contact a
workshop authorised by Volvo CE.
In certain cases also the buzzer sounds at the same time as the
red central warning flashes.
If more than one alarm occurs at the same time, these will be
shown one after the other. If any of the alarms causes red central
warning to flash and in some cases also the buzzer to sound, only
this alarm (these alarms) will be shown.
It is not possible to browse between different levels, e.g. between
orange and red. Reds are always predominant.
