When the CVT-ECU, the CVT assembly
or the valve body assembly is replaced, adopt the system
by using the M.U.T.-III.
|
|
1.Turn the ignition switch
to the "LOCK" (OFF) position. Then, connect M.U.T.-III to
the diagnosis connector.
|
|
2.Turn the ignition switch
to the "ON" position.
|
|
3.Execute the special
function
"Write calibration value (Calibration value Read&save)"
on the M.U.T.-III to read a serial number which is stored in
the CVT-ECU.

|
4.Make sure that the read
serial number corresponds with the one stamped on the CVT
assembly
(see illustration).
note |
If it does not correspond,
observe the following
procedure.
- Remove the oil pan (refer to
),
and check the serial number
of the valve body assembly shown in the
illustration.
- If no serial number is stamped
on the valve body assembly, import data
from the
server to the M.U.T.-III according to
the serial number on the CVT
assembly.
- If a serial number is stamped
on the valve body assembly, make sure
that the read
serial number corresponds with the one
stamped on the valve body assembly (see
illustration).
YES: Store the serial
number in the M.U.T.-III. NO: Import
data from the server to the M.U.T.-III
according to the serial number on the
valve body assembly.
|
5.Store the serial number in the
M.U.T.-III.
note |
Be sure to write down the
serial number. The serial number will be needed
to compare it
with the number imported into the M.U.T.-III and
to select the number.
|
6.Turn the ignition switch to the "LOCK"
(OFF) position. 7.Remove the CVT-ECU and install a
new CVT-ECU (Refer to ). 8.Turn
the ignition switch to the "ON" position. 9.Make
sure that the selector lever is in the P or N range and that
P or N is not displayed
on the combination meter. 10.Execute the special
function
"Write calibration value (Saved calibration value writing)"
on the M.U.T.-III to write the serial number into the
ECU. 11.The shift range symbol (P or N) in the
combination meter should illuminate.
note |
If the shift range symbol (P
or N) in the combination meter does not
illuminate, observe
the following procedure.
- Move the selector lever to the
R range.
- Depress the accelerator pedal
while depressing the brake pedal.
(Engine stops.)
Use the M.U.T.-III special function to
execute "Calibration value reset (item
No.1: Calibration
value reset)" while holding them in
applied position.
- Set the selector lever to the P
range.
- Turn the ignition switch to the
"LOCK" (OFF) position, and then wait for
ten seconds.
- Repeat from Step 2.
|
12.Make sure that the serial number on
"Saved calibration value writing" completion screen
corresponds with the serial number of the CVT assembly (or
the valve body assembly) that was
written down earlier.
note |
If it does not correspond,
observe the following
procedure.
- Move the selector lever to the
R range.
- Depress the accelerator pedal
while depressing the brake pedal.
(Engine stops.)
Use the M.U.T.-III special function to
execute "Calibration value reset (item
No.1: Calibration
value reset)" while holding them in
applied position.

range.
- Turn the ignition switch to the
"LOCK" (OFF) position, and then wait for
ten seconds.
- Repeat from Step 10.
|
13.Turn the ignition switch to the "LOCK"
(OFF) position. 14.Observe the operations
below:
- Wait until the engine is warmed up. Then
road test
the vehicle for approx. one minute at 40 km/h
or more. Consequently, check whether
the CVT is in the following
conditions.
- No CVT-related diagnosis code is
set.
- A diagnosis code is set, but you cannot
identify any trouble symptoms (e.g. abnormal
noise)
- There is no fluid leak.
- Start the engine.
- Teach the system a meeting point. All of
the following conditions must be satisfied
for approximately 90
seconds.
- The vehicle is stationary.
