the injector of malfunctioning cylinder
B
Identify malfunctioning cylinders by conducting power balance test:
S Perform power balance inspection to
identify malfunctioning cylinders
S Clean malfunctioning cylinder injector,
then check and repair it
(a) If revised injection volume of more than
3.0 mm3
Abnormal value cylinder injector injects excessively small quantity of fuel:
S Fuel injection volume too low due to injector nozzle being blocked by deposits
(b) If revised injection volume of less than
−3.0 mm3
Abnormal value cylinder injector injects excessively large quantity of fuel:
S Fuel injection volume too high due to injector nozzle being stuck open by deposits
C
Inspect and repair all cylinder injectors:
S Clean all cylinder injectors, and then inspect and repair them
All cylinder injectors inject excessively
small quantity of fuel:
S Fuel injection volume too low due to all
cylinder injector nozzles being blocked by
deposits
*: When the Injection Volume displayed on the intelligent tester II is too large despite the Common
Rail Pressure and Revised Injection Volume #1 to #4 in the Data List being normal, the injector may
have a clogging malfunction. In this case, there may be deposits inside or outside the injector.
HINT:
S
Despite the injector functioning normally, the indicated Revised Injection Volume #1 to #4 value may be outside the normal operating range due to compensation for other problems (such
as low compression).
S
Revised Injection Volume is the value used to correct the fuel injection volumes of each cylinder, in order to optimize (compensate for the unevenness between) all the cylinder combustion
condition. If any of the cylinders malfunction, the fuel injection volumes for the normal cylinders
are corrected simultaneously. As a result, the Revised Injection Volume may deviate from the
standard range.

*: When the Injection Volume displayed on the intelligent tester II is too large despite the Common
Rail Pressure and Revised Injection Volume #1 to #4 in the Data List being normal, the injector may
have a clogging malfunction. In this case, there may be deposits inside or outside the injector.
HINT:
S
Despite the injector functioning normally, the indicated Revised Injection Volume #1 to #4 value may be outside the normal operating range due to compensation for other problems (such
as low compression).
S
Revised Injection Volume is the value used to correct the fuel injection volumes of each cylinder, in order to optimize (compensate for the unevenness between) all the cylinder combustion
condition. If any of the cylinders malfunction, the fuel injection volumes for the normal cylinders
are corrected simultaneously. As a result, the Revised Injection Volume may deviate from the
standard range.
