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.

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.
