NOTE: The information contained in this document is intended for use by trained, professional technicians with the knowledge, tools, and equipment to properly and
safely perform diagnoses and repairs. It informs service technicians about conditions that may occur in some vehicles, or provides information that could assist in
proper vehicle diagnosis, service, or repair, and does not indicate that a defect is present. DO NOT assume that a symptom or condition, or a described cause of a
symptom or condition, affects any particular vehicle or that a described repair applies to any particular vehicle. There can be multiple causes resulting in the same
symptoms or conditions, and trained professional service technicians must use their diagnostic skills to make evaluations on a case-by-case basis.

SUBJECT:
Waffle Clutch-equipped DUONIC™ Transmission ECU Reprogramming and Initialization
POTENTIALLY AFFECTED MODELS:
2012 M/Y and up Canter vehicles with newly installed waffle type clutch transmissions.
DESCRIPTION:
Please see the attached reprogramming and initialization procedures for waffle clutch-equipped DUONIC™
transmissions.
All Canter vehicles built after August 1, 2013 are produced with a DUONIC™ transmission incorporating this
new clutch design. When installing a waffle clutch equipped DUONIC™ transmission (FE - ME530181XR/FG ME530223XR) in earlier Canters, it is imperative to download correct software for correct application pressure.
Failure to apply correct software will result in premature clutch failure. Such failures will not be covered by
warranty!

(2) Reprogramming
Perform Reprogramming.
* Download an Inquiry Number and Password from the
MFTBC Field Rewrite Network (FRN) in advance.
When the software update is complete, confirm the
software object number and version under the "Version"
tab in the TCM.
Perform “Reset of coding”.
Note: If coding is not reset, some items may not be displayed
during the parameter coding described later.
(3)
Check #013 "Model of clutch" and change parameters according to the vehicle's clutch type.
When installing a waffle type clutch equipped
transmission, change Model of clutch to "Inner clutch
plate B".
Model of clutch
Internal clutch plate
A
[Old] Radial (dot) type
Internal clutch plate
B
[New] Waffle type
Caution:
- If the selected clutch type does not match the clutch on the vehicle, the high temperature alarm may not sound correctly,
which can cause ATF temperature to rise in the clutch, resulting in a clutch seizure.
- When updating to new software, the initial parameter is set to "inner clutch A” (radial (dot) type: old clutch).
If only a software update has been performed, without installing a waffle style clutch equipped transmission, coding for the
clutch type is not required.
However, always check the parameter to ensure the proper clutch parameter is set properly.
- Check the parameter at Actual value #185-6 (calibration value) "Model of clutch".
(4) After checking clutch type, check coding #003：Pulse width modulated signal 'Solenoid valve ''Gearshift''' during
the shift operation
If the value is
・Pulse width modulated signal 'Solenoid valve ''Gearshift'''
during the shift operation<=300Nm：
There is no work to do.
Confirm that the value is "Pulse width modulated signal Solenoid

the value
is during the shift operation <=370_No2". If it is any

other value but this, change
it.
during the shift operation>=370Nm：
Confirm that the text “No2” is included. If not, select the
coding that includes the text “No2”.
(5) Afterrun
・Turn the ignition off and wait 60 seconds. Turn the ignition on again and check for DTC’s.
(6) Perform DUONIC Initialization (see next page)
(7) Upload ECU data
・Perform “Copying to USB storage device” and Upload ECU data
(8) Perform an ECU quick test.

DUONIC™ Transmission Initialization Procedure for
the Waffle Type Clutch
MODELS:
2014 M/Y FEC52, FEC72, FEC92, and FGB72 Canter vehicles produced after August 1, 2013.
DESCRIPTION:
The DUONIC™ electronic control unit initialization process memorizes the transmission’s initial setting.
Initialization must be performed after any of the following have occurred:



Service has been performed on the engine and/or transmission which may have altered or
changed their characteristics.
Automatic transmission fluid (ATF) in the dual clutch housing or the transmission gear oil has
been replaced.
A body has been installed on the chassis.
Before beginning the initialization procedure, ensure that:



Transmission fluid temperatures have reached at least 120°F (50°C).
ATF has been sufficiently circulated through the system by starting the engine and cycling the
gear shift lever through the following positions, remaining in each position for approximately 3
to 5 seconds: “P”  “D”  “R”  “D”  “R”  “D”  “R”  “P”
Tire air pressures are at proper specification.
DUONIC™ Transmission Initialization Procedure:
1. Park the vehicle on a flat, level surface and chock the wheels to prevent movement of the
vehicle.
2. Fully engage the parking brake.
3. Insert the key into the ignition switch and turn to the “ON” position. (DO NOT START!)
4. Using your right foot, fully depress the accelerator to the floor (100% throttle) and hold the
pedal in this position until Step 11.
5. With your left foot, fully depress the brake pedal and hold it in this position until Step 13.
6. With your left hand, move the gearshift selector lever down from the “P” position through “R”,
to “N”, and then left to the “D” position for 1 second.
7. Using your left hand, move the selector lever to the “A/M” position and hold it in this position
until Step 10.
8. Using your right hand, release and fully engage the parking brake lever for 1 second.
9. Release and fully engage the parking brake a second time, then leave the parking brake fully
engaged. The gear position indicator should display a flashing “1” in the multi‐information
display.
10. Release the selector lever and move it to the “P” position.
11. Release the accelerator pedal.
12. Start the engine and leave it running at an idle.
13. Release the brake pedal. The gear position indicator should display a flashing “2”.
14. Monitor the gear shift indicator in the multi‐information display. Immediately after the
indicator starts flashing “5”, turn on the A/C to complete Inner Clutch Torque Learning.
NOTE: The A/C system is used to add a load to the engine. If the ambient temperature is below
70°F, use the cab heater to fill the cabin with a heat load to utilize the A/C system.
15. After approximately 10 to 13 seconds, the engine rotation decreases for a second time. Turn off
the A/C to complete Outer Clutch Torque Learning (See Graph below)
16. When the gear shift indicator flashes “N”, this initialization is complete.
17. Confirm the initialization results. (See next page)
Confirmation Method of the Initialization Results
Confirm (A) and (B) to make sure the initialization is completed. Even if the actual value of (A) is out of
range, perform procedure (B) to confirm whether there is excessive shift shock or not. If there is no
excessive shift shock present, initialization is complete. If the vehicle fails confirmation (A) or (B), please
perform the initialization again.
A) The actual values of the clutch (5kgfm) are within the following values.
B) Ensure there is no shift shock when moving the gear selector lever from “N” to “R”, and then
“R” to “N” while the vehicle is parked.
