Trapping indicator lamps
According to a level of the trapped black
smoke, the "Green" lamps will incrementally
come on one by one and then the "Yellow" will
come on sequentially.
Alarm indicator lamp
This lamp comes on and the buzzer rings
simultaneously to warn you when the amount
of black smoke trapped exceeds the limit or
when malfunction occurs in the DPF System.
Caution Caution
When the alarm indicator lamp comes on,
request an inspection from your Toyota
dealer.
Regeneration indicator lamp
Indicate that DPF regeneration is underway.
Regeneration switch

Caution Caution
Do not start up the engine with the external
power connector plugged in. If so, the
buzzer will sound and the alarm indicator
will blink.
3. During operation
The amount of black smoke trapped is
indicated by the trapping indicator lamp,
the alarm indicator lamp and the buzzer,
in that order.
4. If a malfunction occurs in the DPF Sys-
tem, the alarm indicator lamp comes on
and the buzzer rings for 5 seconds.
Caution Caution
When the alarm indicator lamp comes on,
stop operation and request an inspection
from your Toyota dealer.
5. Operation completion
Carry out DPF regeneration when a day's
operation is over.
Toyota DPF-II System regeneration method
Caution on regeneration Caution
• Use a single phase AC200–240V external
power source, rated 15A or more. Con-
nect securely to a power source earth.
The yellow/green cord of the AC cable
for regeneration is the earth wire.
• Have any repairs to the external power
supply plug done by an electrical special-
ist.
• Always fit an electromagnetic switch with
earth leakage breaker that complies with
the specifications described below to the
external current plug electrical source.
• Rated Current: 15A or 20A
• Sensed Current: 30mA
• Rated Voltage: Single phase AC 200–
240V
• Do not allow water into the DPF air
cleaner when washing the vehicle, etc.
• When the external power is cut off for one
minute or longer due to power outage
among others, the abnormality is
detected, and the operator is notified by
the blinking of the regeneration indicator
lamp. At this time, after confirming that
the external power has been normally
restored, conduct regeneration again.
• Check that there are no objects that can
easily catch fire around the DPF System
before carrying out regeneration.
Select a location for regeneration which
is well ventilated (with a draught), away
from the rain and not near any waste
paper etc. that can easily catch fire.
• Do not handle the power plug with wet
hands. A high voltage is used (single
phase AC200–240V), so there is a danger
of electric shock.
• Before starting DPF regeneration opera-
tion, make sure that a specified external
power is supplied to the machine.
So long as the external power is not sup-
plied, regeneration will fail to start, even
if attempted.
• During regeneration operation, combus-
tion smoke is emitted out of the tail pipe.
