CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the
M.U.T.-III.
When detecting fault and storing the diagnosis code,
the ECU connected to CAN bus line obtains the data
before the determination of the diagnosis code and
the data when the diagnosis code is determined, and
then stores the ECU status of that time. By analysing
each data from M.U.T.-III, the troubleshooting can be
performed more efficiently. The displayed items are
as the table below.

TROUBLESHOOTING PROCEDURE
WHEN VEHICLE POWER DOES NOT
TURN ON

M1429628300042

When the power does not turn ON, open and close
the driver's door several times. Then, check the com-
munication between OSS-ECU and M.U.T.-III and
others as shown in the flowchart below. (OSS-ECU
can communicate with the M.U.T.-III even when the
power supply is OFF.)

AC905152

Is the communication with
M.U.T.-III possible?

· Battery failure
· Malfunction of the CAN-C/CAN-C-Mid bus line
· Malfunction of ETACS-ECU (power supply, earth system)
· Malfunction of OSS-ECU (power supply, earth system)

Is the diagnosis code
set?

Carry out the OSS-ECU check by
diagnosis code.
(With the forcible power supply
output using the M.U.T.-III,
distinction from failure of another
systems is possible.)

Is it possible to turn ON the
power when the keyless operation
key is placed in the key box?

Diagnose the KOS-ECU.
· Low battery voltage of
keyless operation key, etc.

Carry out the OSS-ECU check
by trouble symptom.
· Power does not turn on.
(not possible with both of power
supply mode ACC and ON)

Yes

FORCED POWER SUPPLY OUTPUT
PROCEDURE

M1429627400013

With OSS, the power supply cannot be turned ON
until the certification communication with KOS and
electrical steering lock is complete. However, using
the M.U.T.-III, the power can be forced ON even
when the certification communication with KOS and
electrical steering lock is not completed. (However,
locking/unlocking of the electrical steering lock is not
performed.) Through this process, the error in certifi-
cation with KOS or electrical steering lock can be dis-
tinguished from the malfunction in power supply. In
addition, the process allows the CAN bus diagnosis
as well as the reading of diagnosis code, belonging
to systems other than OSS, to be performed.

FORCED POWER SUPPLY OUTPUT
PROCEDURE

1. Connect the M.U.T.-III to the diagnosis connector.

2. On the M.U.T.-III system selection screen, select

"OSS."

3. Select "Special Function" from OSS screen.

4. Select "Forced power supply output" from Special

Function screen.

5. From the forced power supply output screen,

select the status with which the control is desired.
(Selection can be made from IG-ACC, IG-ON, and
IG-ST.)

6. On the execution confirmation screen, select OK.

7. While the process is executed, the selected

control status is maintained.

NOTE: During the forced power supply output, the

indicator flashes in orange.

8. To cancel the forced power supply output, select

"Forced power supply output (stop)" on the
Special Function screen, or operate the engine
switch.
