3. Warning indication and
countermeasures
Before starting the day's job, check the fluid level with
the DEF/AdBlue
®
gauge on the instrument panel.
If the fluid runs short during operation, the warning
indicator lights up. If you continue running the machine
as it is, the engine output will be limited by 50% or so. If
running is continued, the engine will be limited to idling.
(See SCR system inducement display and measures
on page 42.)
These limitations are stipulated in conformity with the
emission controls of each country and territory.

3.2.1 Diagnostic trouble code (DTC)
DTC can be used to diagnose the problem in engine
and SCR muffler.
For example,
“ENG P-208B”
: the code beginning with
the letter “P” or “U” is the DTC.
If a DTC appears, immediately contact your local
KUBOTA Dealer.
NOTE :
• When operating in cold weather, the DEF/
AdBlue
®
is automatically thawed while the
engine is running. However, in weather
conditions of under -30
℃
(- 22
℉
), the DEF/
AdBlue
®
cannot be completely thawed and
thus, a DTC (
“ENG P-208B”
) appears on the
instrument panel's LCD screen.
If the DTC (
“ENG P-208B”
) appears on the screen,
stop the engine and restart it after 10 seconds.
After restarting the engine, the DTC (
“ENG
P-208B”
) will disappear and the thawing of the
DEF/AdBlue
®
will resume.
In case the DTC (
“ENG P-208B”
) remains on the
screen even after restarting the engine several
times, contact your local KUBOTA Dealer.
