NOTE: After the engine-ECU has detected a malfunction, the engine warning lamp illuminates when the

engine is next turned on and the same malfunction is re-detected. However, for items marked with a "

*

1" in

the diagnosis code number column, the engine warning lamp illuminates only on the first detection of the mal-
function.

NOTE: The codes marked with a "

*

2" in the diagnosis code number column have the following two conditions

for illuminating the engine warning lamp.

.

•

In case that the misfire causing the damaged catalyst is detected, the engine warning lamp will flash until
the condition is corrected. If the system detects the same malfunction after the next engine start and then
the condition is corrected, the engine warning lamp will flash (not illuminate).

•

In case that the misfire deteriorating the exhaust gas is detected, the engine warning lamp is illuminated
when the same malfunction is redetected after the next engine start.

NOTE: Even if the malfunction is not detected when the engine-ECU monitors the malfunction three consec-
utive times* after the engine warning lamp illuminates, turn off the engine warning lamp when the engine
starts next time.

*: In this case, "one time" in monitoring the malfunction means the period from the time of the current engine
start to the time of the next engine start. "One time" in monitoring the misfire or the fuel system malfunction
means the time when the operating conditions (such as the engine speed or the engine coolant temperature)
becomes similar operating conditions of the first detected malfunction.

METHOD OF READING AND ERASING
DIAGNOSIS CODES

Refer to GROUP 00

− How to Use Troubleshoot-

ing/Inspection Service Points

− Diagnosis Function .

INSPECTION WITH M.U.T.-III DATA LIST
AND ACTUATOR TEST

Reading data list or performing an actuator test using
M.U.T.-III enables you to check the vehicle body har-
nesses and components for abnormalities. Sensor
input or output to the actuator can be displayed in
numerical values or graphs in the data list while in
the actuator test the actuator can be forced to drive
(ON/OFF driving in the specified time).

DIAGNOSIS PROCEDURE

1. Connect M.U.T.-III to perform inspection with the

data list and actuator test function.

2. If any abnormality is found, inspect and repair

vehicle body harnesses and components.

3. After repair, check that input and output have

returned to normal.

4. If a failure code which is caused by inspection

and repair work is generated, erase the failure
code.

5. Disconnect M.U.T.-III and perform a test run to

check that the malfunction phenomenon is
resolved.

PROVISIONAL DIAGNOSIS CODE CON-
FIRMED

If detecting the malfunction during the first drive
cycle, the engine-ECU temporarily stores the diagno-
sis code as the provisional diagnosis code. If detect-
ing the same malfunction during the next drive cycle,
the engine-ECU determines that the malfunction
exists. The engine-ECU outputs the diagnosis code.
On the M.U.T.-III, it is possible to display the stored
provisional diagnosis code which the engine-ECU
had detected during the first drive cycle. This makes
it possible to confirm in one drive cycle whether the
malfunction could happen again after the repair.

CONFIRMATION METHOD

1. After the ignition switch is in "LOCK" (OFF) posi-

tion, connect the M.U.T.-III to the diagnosis con-
nector.

2. Turn the ignition switch to the "ON" position.
3. Select "MPI/GDI/DIESEL" from System select

Screen of the M.U.T.-III.

4. Select "Special Function" from MPI/GDI/DIESEL

Screen.

5. Select "Provisional DTCs" from Special Function

Screen.

FREEZE FRAME DATA

When the engine-ECU detects a malfunction and
stores a diagnosis code, it also stores a current sta-
tus of the engine. This function is called "Freeze
frame data". By analyzing this "Freeze frame" data
with the M.U.T.-III, an effective troubleshooting can
be performed.
The display items of freeze frame data are shown
below.

NOTE:

*

1: Accumulated time of current malfunction from time point when malfunction is detected.

NOTE:

*

2: The items can be seen by selecting "Freeze Frame Data (OBD)" on Self-diagnosis Screen of

MUT-III. If detecting multiple malfunctions, the engine-ECU stores the data for only the first item that was
detected. If detecting the misfire or fuel system malfunction, the engine-ECU stores the data by giving priority
to the misfire or fuel system malfunction in spite of the chronological order of the detected malfunction.

NOTE: The Freeze Frame Data (OBD) should not be stored for the diagnosis code when the engine warning
lamp does not illuminate.

NOTE:

*

3: Condition in which oxygen sensor signals are fed back to the engine-ECU for controlling fuel.

NOTE:

*

4: Condition in which fuel is controlled without oxygen sensor signals being fed back to the

engine-ECU because the condition to shift to the closed loop is not met.

NOTE:

*

5: Data items are displayed on M.U.T.-III display, but the in-line 4 engine is not applicable and its data

is displayed as "N/A" or "****".

FAIL-SAFE AND BACKUP FUNCTION

This function exercises control, by predetermined
control logic, to keep a condition in which a vehicle
can be safely driven when main sensor failures are
detected by the diagnosis function.
