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 fuel rail pressure sensor
connector and then IMV connector. 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.

Pressure leak test in fuel system with scan tool ▶
When the dynamic test for injector backleak is performed, this test should be done together with it.
However, you can check the pressure leak from the fuel system only with this test.

470096009d008c00990047005d0057020b006a00550047006a>heck the conditions of sensors
and components in fuel system with scan tool.
Perform the diagnostic test as follows: 1.
2.
3.
Select the "Vehicle Model" and go to "Diagnosis Mode".
Select "Pressure Leak Test in Fuel System" in "Diagnosis Menu".
If the conditions are OK, press "Start". -
-
-
The pressure leak test procedure is performed in 4 cycles. The engine speed goes up to
3,500 rpm and down again four times for 18 seconds. If the system is OK, the "System OK"
message will be displayed.

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 range. 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
