power derate. This engine power restoration works only when the Inducement status is “Severe Induce-
ment” and relieves back temporarily to the power deration of “Low level Inducement”. The operator can re-
store engine power through the machine monitor. For the engine power restoration procedure, refer to the
section of “Temporary Restoration from Inducement” in this manual. If Inducement advances to “Severe In-
ducement” and it becomes necessary to restore engine power, use the engine power restoration function to
move the machine to a safe place and contact your Komatsu distributor.
Inducement strategy when abnormality is found in the EGR Valve System by the
Urea SCR system
If any abnormality is detected in the EGR Valve System through the Urea SCR system, the Inducement strategy
is activated.
The inducement strategy progresses in 4 levels, “Warning”,
“Continuous Warning”, “Low level Inducement”, and “Severe In-
ducement”. The Inducement strategy includes visual alert by
the Engine system caution lamp (1), DEF system caution lamp
(2), and Action Level displayed on the machine monitor (3), au-
dible alert by a buzzer and stepwise engine power deration that
advances to speed limitation to low idle. Engine power deration
starts with Action Level “L03 (Warning, Continuous Warning
and Low level Inducement)” and advances to further deration
when “L04 (Severe Inducement)” is displayed. Once the sys-
tem advances to “Severe Inducement”, the engine power will
be further derated. If “L03” is displayed, move the machine to a
safe place and contact your Komatsu distributor.
The content of the warning can be checked on the “SCR Information” screen of the user menu.
Perform the following procedure.
Press the menu switch to display the “SCR Information”
screen.
After a lapse of 3 seconds to stop the machine, “SCR Informa-
tion” screen is displayed.
“SCR Information” screen displays remaining time to the next
Inducement status in the column (6), and information on the
Urea SCR System condition (4), and the current status of In-
ducement (5).
