GENERAL

OUTLINE OF CHANGES

Due to the changes shown below, the service procedures regarding the different description from the
previous version have been established.



On-board Diagnostics System has been adopted to expand the diagnostic items and to change diagnosis
code numbering system.



Fuel pressure regulator (high-pressure) incorporate fuel pump (high-pressure) has been adopted.



An oxygen sensor (rear) has been added.



A ignition failure sensor has been added.



Lead cables of the crank angle sensor have been contained in the timing belt cover.



An accelerator pedal position sensor attached to the accelerator pedal has been adopted.



An engine-ECU has been changed.(Change of terminal layout) <Vehicles with M/T>



An engine-A/T-ECU has been adopted. <Vehicles with A/T>

GENERAL INFORMATION

SELF-DIAGNOSIS FUNCTION

Following functions have been added.



The engine-ECU records the engine operating condition when the diagnosis code is set.
This data is called “freeze frame” data.
This data can be read by using the MUT-

II

, are can then be used in simulation tests for troubleshooting.

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.
