Initialization of DUONIC

system

Initializing the DUONIC

system stores the GSU (gear

shift unit) gear position, road surface grade zero point
correction value, clutch fill time learning value and
clutch torque learning value in the memory of the TCU.
It must be performed after ANY type of transmission-
related service.

If any abnormality occurs during normal running, it
may be cleared by initialization. Some kinds of body
equipment work to the vehicle can cause an error in
road surface grade recognition. To prevent this, be
sure to initialize the DUONIC

system under the

following conditions after body equipment work.

Conditions for initialization

Check the following before initialization.

(a) The engine electronic control unit and

DUONIC

electronic control unit (TCU) are

finished with flashing (programming) and
coding (in case of a change in tire size or final
ratio). For details, contact a MITSUBISHI FUSO
service center.

(b) To compute the road grade zero point

correction value, make sure that the vehicle is
in the following state:

• Standing still, brake released, on a flat surface

such that the vehicle remains stationary
without drifting forward or backward

• Equipped with specified wheels with the tires

filled to correct pressures.

• Cab tilt locked (a G sensor is provided in the

cab.)

the engine, such as the following, must be
stopped:

• Air conditioner
• Load for equipment (compressor for refrig-

erator, etc.)

• Exhaust brake

Change lever pattern

Initialization procedure

(a) In case of failure of initialization
• Repeat the initialization procedure from the

start.

• If initialization still goes wrong, there may be a

problem with the hardware. Check the
transmission (including gears, clutch,
associated parts, valve body and GSU) and their
connections.

• If the indicator shows from [2] to [R] blinking,

move the vehicle once, then perform the initial-
ization procedure. The problem may be
resolved.

Operation

Resultant status

Remarks

• Hold vehicle on flat surface. (3.8.3

(b))

• Turn key ON.
• Stop engine.
• Switch off air conditioner,

equipment load and exhaust
brake. (3.8.3 (c))

• Accelerator ON (50% or more)
• Foot brake ON
• Change lever

D → (hold for approx. 1 second)
→ Hold A/M

• Parking brake

ON → (hold for approx. 1 second)
→ OFF → (hold for approx. 1
second) → ON (pull a little hard)

[Initialize mode standby status] is
established and indicator shows [1]
blinking.

[To clear initialize mode
standby status to return to
normal mode], release
parking brake or turn key OFF
and hold it OFF for 1 second.

From initialize mode standby status,

• Turn accelerator OFF
• Place change lever to [P].

Then, start engine.

• With progress of initialization,

indicator shows [2-3-4-5-N]
blinking in that order.

• If initialization goes wrong, [R] is

shown blinking.

Even if foot brake is released
after engine is started,
initialize mode remains, but
for safety, foot brake should
be kept ON.

(Status by indication)

[2] Detection of GSU gear position in

progress

[3] Clutch warming up + road grade

zero point compensation in
progress

[4] Clutch fill time learning in

progress

[5] Clutch torque learning in progress
[N] Initialize completed
[R] Initialize failed

Release parking brake or turn key
OFF and hold it in that state for 1
second.

Mode is returned to normal.

3.8.4

Resetting of initial DUONIC

settings

The DUONIC

system has a reset function for

restoring the initially set GSU gear position, road
grade zero point compensation value, clutch fill time
learning value and clutch torque learning value to the
pre-initialization status. (This is a back-up function
used in case any initial settings are found to be
abnormal and affect the vehicle operation; it is not
normally used.)

Cautions during body equipment work on
DUONIC

vehicle

The DUONIC

transmission and control system is a

computerized and electronically controlled system;
mishandling could cause system errors and in the
worst case, breakdown of the computer itself.
Therefore, body equipment work on the vehicle should
be carried out with following the precautions given
below.

General handling precautions

• Be sure not to change the tire size, final ratio, and

speedometer gear ratio of a DUONIC

vehicle.

• Be sure not to alter DUONIC

-associated devices,

sensors, harnesses and connectors in any way.

• Before disconnecting DUONIC

-associated

connectors, set the starter switch of the vehicle to
OFF. Before turning the starter switch ON,
reconnect the disconnected connectors.
If DUONIC

-associated device connectors are

disconnected while power is supplied to the TCU, a
warning lamp will light or the system may lose
functionality.

• Before painting the transmission body, mask

electric parts, harnesses, connectors, breathers,
oil cooler pipe joints and other parts which should
be covered.
Furthermore, mask wrong fluid/oil supply
preventive labels (ATF ONLY, GEAR OIL ONLY)
attached near to appropriate fluid/oil plugs so that
they are not covered with paint.

• After completing the body equipment work on the

vehicle, make sure that the vehicle runs without
any problem.

Operation

Status

Remarks

• Turn key ON.
• Stop engine.
• Accelerator ON (50% or more)
• Foot brake ON
• Change lever

D → (hold approx. 1 second) →
Hold A/M

• Parking brake

ON → (hold approx. 1 second) →
OFF → (hold approx. 1 second)
→ ON

[Initialize mode standby status] is
established and indicator shows
[1] blinking.

[To clear initialize mode standby
status to return to normal mode],
release parking brake or turn key
OFF and hold it OFF for 1 second.

From initialize mode standby status,
place change lever to [–].

With resetting completed,
indicator [6] blinks.

Release parking brake, or hold key
OFF for 1 second.

Mode returns to normal.

3.8.6

Power take-off for DUONIC

(mechanical

automatic transmission)-equipped
vehicle

The vehicle cannot be run while the power take-off is
in operation.

Vacuum-type power take-off operation procedure

• With the engine running, place the shift lever into

the P position (or N position).

• Set the power take-off main switch in the cab to

ON.

• The indicator lamp

lights to indicate that the

power take-off is in preparation.

• With the indicator lamp

on, the power take-off

can be used.

• To clear this status, set the power take-off main

switch in the cab to OFF. The indicator lamp

goes off and the indicator lamp

goes on. The

power take-off is being released.
The indicator lamp

goes off to indicate that the

power take-off has been released.

Cable type power take-off operation procedure

• With the engine running, place the shift lever to the

P position (or N position).

• Set the power take-off main switch in the cab to

ON.

• The indicator lamp

lights.

• Connect the power take-off by means of the power

take-off lever or damp lever.

• The indicator

goes on to indicate that the

power take-off is operational.

• To release the power take-off, set the power take-

off main switch in the cab to OFF. The indicator
lamp

goes off and the indicator lamp

goes

on to indicate that the power take-off is ready to be
released.
Release the power take-off by means of the power
take-off lever or damp lever. The indicator lamp

goes off to indicate that the power take-off has

been released.

Cautions

• The indicator lamp

may not show, depending

on the sequence, operating speed or device
response speed, which is not an abnormality.

• If the shift lever is in a position other than P or N,

the power take-off is not connected even if the
power take-off switch is turned ON. In the case
where the shift lever is in a position other than P or
N or the power take-off switch is turned to ON
during running, the buzzer sounds and the warning
indication of

appears on the meter. Turning

the power take-off switch to OFF restores the state
to normal.

• If the shift lever is placed into a position other than

P or N or the power take-off switch is turned to ON
when the power take-off is working, the buzzer
sounds and the warning indication of

appears

on the meter.
