Inducement strategy when abnormality is found in the KDPF System by the
Urea SCR system
If any abnormality is detected in the KDPF System through the Urea SCR system, the Inducement strategy is
activated.
The inducement strategy progresses in 5 levels, "Warning",
"Escalated Warning", "Mild Inducement", "Severe Inducement"
and "Final Inducement". The Inducement strategy includes vis-
ual alert by the KDPF System caution lamp (1), DEF system
caution lamp (2), and Action Level displayed on the machine
monitor (3), audible 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 (Mild In-
ducement)" and advances to further deration when "L04 (Se-
vere Inducement and Final Inducement)" is displayed. Once
the system advances to "Final Inducement", the engine speed
is fixed to low idle. 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.
