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". -

-
-
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
Red area on the left-hand side of OK
(④): Impossible to charge with an
alternator
Green area with OK (⑤): Normally
charged

(2) Passive LOCK
When the system searches for a smart key by the input from the outside door handle switch, the SKM
sends the passive LOCK signal to the BCM if all the doors are closed and a normal smart key is found
outside the vehicle.
Passive LOCK hardware control ▶
The SKM sends the door LOCK/UNLOCK signal to the BCM through the BCAN network when a
smart key is verified after the signal from the driver/passenger outside door handle switch is received
through the hardware.
The SKM sends the signal to the BCM and instrument cluster when the warning and indicator
display conditions are met. 1.
2.
Passive LOCK by outside door handle switch ▶
When the ignition status is OFF, ACC ON or IGN ON, the SKM performs the verification procedure if the
LOCK signal is received from the driver/passenger door handle switch.
When the outside door handle switch is operated, the SKM verifies if a smart key is outside the
vehicle using the corresponding exterior antenna.
The SKM sends the signal for [Passive LOCK command] to the BCM through the BCAN if a smart
key is identified as being outside the vehicle.
If no smart key is verified as being outside the vehicle, this process is stopped and restarted when the
next signal is received from the outside door handle switch.
When the driver's door is unlocked with the ignition status ACC ON, the SKM changes the ignition
status to OFF and sends the signal for [Passive LOCK command] to the BCM through the BCAN to
lock the door. The BCM ignores the signal if the ignition status is IGN ON.
The SKM recovers the deactivated smart key function inside the vehicle when it receives the theft
deterrent deactivation signal from the BCM through the BCAN communication. 1.
