2) Diagnostic Test for Engine Fuel System
(1) Overview
If a DTC is displayed on the diagnostic device, check the low pressure- and high pressure fuel
systems before removing the components.
To run the system properly, the electric system must be intact but for the DI engine, the fuel
pressure should be measured also when there is a malfunction even after the diagnostic test with
a diagnostic device.

(5) High Pressure System Pressure Test
Fuel rail pressure test ▶
Disconnect the pressure sensor connector
(A) and IMV connector (B) from the fuel
rail. 1.
Connect the pressure tester to the fuel rail
pressure sensor connector. 2.
Crank the engine 2 times for 5 seconds. 3.
Read the highest pressure value
displayed on the tester display.
If the highest pressure value is 1,050 bar
or less, refer to the section "Fuel System
Check Process". -

How To Use Pressure Tester ▶
Press the "TEST" button on the tester to
check if the message "TEST?" is
displayed.
If the button is pressed again at 4 seconds
after starting engine cranking, the highest
pressure is displayed on the tester. 1.
2.
The fuel rail pressure value can be checked using a diagnostic device.

HP pump pressure test ▶
Prepare a special tool for high pressure
test and clean it thoroughly to prevent
foreign materials from entering. 1.
Disconnect the high pressure fuel supply
pipe on the HP pump and install the close
rail in the tool kit. 2.
Connect the other end of the close rail to
the fuel rail for test. 3.
Disconnect the return hose for HP pump
and connect the clear hose and connect its
the other end to the return port of the fuel
rail for test. 4.
Connect the digital tester connector to the
sensor connector of the fuel rail for test.
Crank the engine 2 times for 5 seconds after
removing the IMV connector and fuel rail
pressure sensor connector.
Read the pressure value displayed on the
tester display is within the specified. 5.

(1) Checking
Using battery tester ▶
PASS (11.0 V or more): Explain to the customer that the battery is reusable.
Need to be charged (9.0 to 11.0 V): Charge the battery with a charger and reinstall it. Explain it
to the customer.
Need to be replaced (9.0 V or more): The battery should be replaced due to overdischarging. -
-
-
(2) How to use battery tester
How it works and How to use it ▶
Determine battery capacity by fixing current
(load capacity) and time and varying voltage.
Determine battery capacity based on the
amount of voltage drop when discharging a
fixed load capacity (120 A) for 5 seconds.
Connect the tester to the battery and read
the display while applying a load for 5
seconds. -

-
How to read display ▶
Red area (①): overdischarge or faulty
battery
Yellow area (②): Need to be charged (using
a vehicle alternator and a battery charger)
Green area (③): Normal
Red area on the left-hand side of OK (④):
Impossible to charge with an alternator
Green area with OK (⑤): Normally charged
Red area on the right-hand side of OK (⑥):
Overcharged by an alternator -
