DIAGNOSIS FUNCTION

ENGINE WARNING LAMP (CHECK ENGINE LAMP)

If an abnormality occurs in any of the following items related
to the GDI system, the engine warning lamp will illuminate
or flash. If the lamp remains illuminated or if the lamp illuminates
while the engine is running, check the diagnosis code output.
However, the warning lamp will illuminate as bulb check for
five seconds whenever the ignition switch is turned to the
ON position.

NOTE
1.

If the engine warning lamp illuminates because of a malfunction of the engine-ECU, communication
between MUT-

II

 and the engine-ECU is impossible. In this case, the diagnosis code cannot be read.

2.

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 “



”

in the diagnosis code number column, the engine warning lamp illuminates only on the first detection
of the malfunction.
As for P1220, P1221, P1223, P1224, and P1228, the engine warning lamp flashes. If malfunctions
are detected at the throttle position sensor (1st channel) and the throttle position sensor (2nd channel)
at the same time, or malfunctions are detected at the accelerator pedal position sensor (1st channel)
and the accelerator pedal position sensor (2nd channel) at the same time, the engine warning lamp
will flash.

3.

After the engine warning lamp illuminates, it will be switched off under the following conditions.
(1) When the engine-ECU monitored the power train malfunction three times* and met set condition

requirements, it detected no malfunction.
*:

In this case, “one time” indicates from engine start to stop.

(2) For misfiring malfunction, when driving conditions (engine speed, engine coolant temperature, etc.)

are similar to those when the malfunction was first recorded.

4.

Sensor 1 indicates the sensor mounted at a position closest to the engine, and sensor 2 indicates
the sensor mounted at the position second closest to the engine.

METHOD OF READING AND ERASING DIAGNOSIS
CODES

Refer to GROUP 00 – How to Use Troubleshooting/Inspection
Service Points.

DIAGNOSIS USING DIAGNOSIS 2 MODE

1.

Switch the diagnosis mode of the engine control unit to
DIAGNOSIS 2 mode using the MUT-

II

.

2.

Carry out a road test.

3.

Take a reading of the diagnosis code and repair the problem
location.

4.

Turn the ignition switch to OFF and then back to ON again.

NOTE
By turning the ignition switch to OFF, the engine-ECU
will switch the diagnosis mode from DIAGNOSIS 2 mode
to DIAGNOSIS 1 mode.

5.

Erase the diagnosis codes.

INSPECTION USING MUT-

II

 DATA LIST AND

ACTUATOR TESTING

1.

Carry out inspection by means of the data list and the
actuator test function. If there is an abnormality, check
and repair the chassis harnesses and components.

2.

After repairing, re-check using the MUT-

II

 and check that

the abnormal input and output have returned to normal
as a result of the repairs.

3.

Erase the diagnosis code memory.

4.

Remove the MUT-

II

, and then start the engine again and

carry out a road test to confirm that the problem has
disappeared.
