(6) Low Pressure System Pressure Test
Inspection procedure ▶
All wirings/connectors and fuel lines should
be connected and the engine should work
properly.
Prepare a special tool for low pressure test
and clean it thoroughly to prevent foreign
materials from entering. 1.
2.
Disconnect the key connector for fuel filter connection, and connect both connectors to the fuel filter
and hose. 3.
Start the engine and check visually for clogged low pressure fuel system, excessive air or air entry.
If the fuel flow is not sufficient or air is in the fuel, repair the leak area. 4.

If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a
malfunction in the charge system including the battery. Therefore, carrying out the system check is
needed.
(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the
battery cables with the ignition key turned to ON or ACC position, several electric units can be
damaged due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted
with soapy water. -

(14) Immobilizer control
A. Overview
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is
turned to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if
correct, allows the vehicle to start the engine.

C. Key approval process
When turning the ignition switch to ON position, the power is supplied to BCM and ECU. ECU
communicate with the immobilizer key to check if it is valid crypto code. If it is valid, ECU start to control
the engine when turning the ignition switch to START position. The system has 10 seconds of valid
time-out period. If the engine does not start in this period, the key approval process should be done
again.

1) Wiper Control
(1) Wiper MIST and Washer Coupled Wiper
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch for 0.2 ~
0.59 seconds (T2) with the ignition key “ON”, and it is turned off when the parking terminal
is turned off. 1.
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch over 0.6
seconds (T2) with the ignition key “ON”, and it is turned on three times immediately after
turning off the washer switch. 2.
