KDPF SOOT ACCUMULATION CAUTION LAMP
The KDPF soot accumulation caution lamp warns that the soot
is accumulated in KDPF or the filtering function of KDPF has
lowered abnormally.
To clear the alarm, perform the manual stationary regeneration
of KDPF.
When abnormal
The caution lamp lights up in red, and the action level “L03” is
displayed.
The alarm buzzer sounds intermittently.
Large accumulation of soot in KDPF or a system failure such
as lowering of the filtering function of KDPF occurred.
Urgent remedy is required.
Move the machine to a safe place immediately and perform the manual stationary regeneration.
The manual stationary regeneration may start automatically to protect the KDPF system.
When soot is accumulated
The caution lamp lights up in yellow, and action level “L01” is displayed.
Much soot is accumulated in KDPF, however, the operation can be performed.
After the operation is finished, move the machine to a safe place and be sure to perform the manual stationary
regeneration.
REMARK
For the manual stationary regeneration, see “HANDLE Komatsu Diesel Particulate Filter (KDPF) (3-118)”.

Fault conditions that result in activation of the Inducement strat-
egy for engine derates to prompt to maintain or repair the emis-
sion control system.
When Lightning in red
With Action level “L04”, DEF tank level is too low. Inducement
status is “Severe Inducement”. Engine power is under heavy
deration. Hybrid system power is also under deration. This results in low swing motor power.
With Action level “L03”, DEF tank level is low. Inducement status is “Low level Inducement”. Engine power is
under deration. Hybrid system power is also under deration. This results in low swing motor power.
With No Action level display. DEF tank level is lower. Inducement status is “Continuous Warning”. Need to add
DEF immediately to avoid advancing to the next Inducement status.
With No Action level display. DEF tank level is becomes low. Warning starts. Inducement status is “Warning”.
Need to add DEF immediately.
When Lightning in white
When fluctuation of DEF tank level is large, frozen, or not limited to, tank level sensing is not performed correct-
ly.
When DEF is added after engine starting switch is turned to OFF position.
When DEF tank level sensor is defective.
