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.
