WARNING

A high-tension voltage is flowing between
the engine-ECU and the injectors while the
engine is running. Handle them carefully to
avoid receiving electric shocks from the volt-
age.

CAUTION

After replacing the engine-ECU, register the
injector identification code and learn fuel injec-
tion. (Refer to GROUP 00

− Precautions Before

Service

− What The Common Rail Engine Learns

)

CAUTION

After replacing the injector, register the injector
identification code and learn fuel injection. (Refer
to GROUP 00

− Precautions Before Service −

What The Common Rail Engine Learns ).

CAUTION

After replacing the supply pump, learn the supply
pump. (Refer to GROUP 00

− Precautions Before

Service

− What The Common Rail Engine Learns

).

CAUTION

The vehicle equipped with the DPF shall initialize
the learning value after the following parts are
replaced (Refer to GROUP 00

− Precautions

Before Service

− Initialization Procedure for

Learning Value in Diesel Particulate Filter (DPF)
System <Euro5> ).

• DPF
• Exhaust differential pressure sensor
• Catalytic converter
• Engine oil

DIAGNOSIS FUNCTION

M1133003800954

ENGINE WARNING LAMP (CHECK
ENGINE LAMP)

When the abnormal condition occurs with respect to
the items of electronically controlled fuel injection
system shown in the table, the engine warning lamp
is illuminated. When the lamp remains illuminated
after the engine start, or when the lamp is illuminated
while the engine is running, check the diagnosis
code output. There are two methods for checking the
indicator lamp burn out: When the ignition switch is in
ON position, the indicator lamp is illuminated, and
then extinguished few seconds later. When the igni-
tion switch is in ON position and the engine starts,
the indicator lamp is extinguished.

ENGINE WARNING LAMP INSPECTION ITEMS

CAUTION

The engine warning lamp continuously illuminates when the engine-ECU malfunctions.
