FUEL SYSTEM
DTC P0611 INJECTOR CIRCUIT MALFUNCTION (MORE THAN TWO
INJECTORS)
COMPONENT LOCATION
ECDE1443
Injector
LFIG257A
GENERAL DESCRIPTION
EB9B42E6
Injectors spray fuel in the highly compressed combustion chamber, and power generates through combustion process.
Fuel pressure is raised to 1600bar in common rail diesel engine for the purpose of making fuel into minute particles. And
fuel devided into minute particles leads smoke reduction, high power generation, and improved fuel efficiency. To control
pressure of 1600bar with solenoid, oil pressure servo is applied. And injector solenoids is actuated by solenoid operating
voltage raised to 80V with the method of current control.
DTC DESCRIPTION
ED515DBC
P0611 is set when the problems of more than 2 injector circuits are detected thus, it is difficult to find abnormal injector.
Check "Circuit Inspection" of all injectors

TERMINAL AND CONNECTOR INSPECTION
EEE364CD
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
