NOTE
When removing the fuel pump (high pressure), air may
get into the fuel pump (high pressure). If air gets into
the fuel pump (high pressure), diagnosis code No.56 for
abnormal fuel pressure will be output.
2. Use the MUT-IIto check the diagnosis code. If the
diagnosis code No.56 for fuel pressure sensor system
defect is output, erase it.

O-RING/FUEL PRESSURE HOSE INSTALLATION
1. Apply a small amount of fresh engine oil to the O-ring.
Caution
Take care not to let any of the engine oil get inside
the fuel pump (high pressure) or the delivery pipe
assembly.
2. While being careful not to damage the O-ring, turn the
fuel pressure hose to the left and right and connect it
to the delivery pipe assembly. After connecting, check
that the fuel injector turns smoothly.
3. If the fuel pressure hose does not turn smoothly, the cause
may be that the O-ring is getting caught. Remove the fuel
pressure hose, check the O-ring for damage and
re-connect the fuel pressure hose to the delivery pipe
assembly and then re-check.

DRIVE CYCLE
Performing the running test of the car using the following five drive cycle patterns makes it possible to
monitor all the diagnosis codes that are required for operation of the car in order to determine if the
applicable system is operating properly or not.
In other words, doing such a drive allows to regenerate any kind of trouble which involves illuminating the
Engine Warning Lamp (Check Engine Lamp) and to verify the repair procedure has eliminated the trouble
[the Engine Warning Lamp (Check Engine Lamp) is no longer illuminated].
Caution
Two technicians should always be in the vehicle when carrying out a test drive.
NOTE
Check that the diagnosis code is not output before traveling in the Drive cycle pattern. Erase the diagnosis
code if it has been output.
