2. CHECKING CABLES AND WIRES
Check for loose connection or rust.
Check terminals and wires for corrosion due to electrolyte leakage.
Check terminals and wires for open circuit.
Check the wire insulation and coat for damage, cracks or deterioration.
Check if the conductive parts of the terminals do not contact with vehicle body or other metal
parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
Check that wires are properly routed.
Make sure that wires are securely fixed to avoid contact with sharp body parts and
hightemperature
parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be
secured tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such
as the engine, after slackening it slightly to prevent it from being damaged. -

The certification for the immobilizer is performed when turning the ignition switch to the "ON"
position after the CAN communication between the ECU and immobilizer is established.

2. 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. If the verification has been failed,
the engine cannot be started and the immobilizer warning lamp blinks.

3. VERIFICATION OF KEY
1) Verification
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the
engine. The transponder inside the key communicates with the immobilizer installed in the key
box, and the system permits the engine to start after confirming the encrypted coding from the
engine ECU.
In the following cases, a driver may be unable to start the vehicle with the immobilizer.The immobilizer unit transmits
the encrypted code to the
transponder. (2)
The transponder sends an encrypted signal to the unit as a response.
The transmitted code is changed to an encrypted signal in the unit.
The system compares the signal from transponder and the encrypted signal in immobilizer unit. (3)
(4)
(5)
When two or more immobilizer keys come into contact with (each) other(s).
When the key is close to any device sending or receiving electromagnetic fields or waves.
When the key is close to any electronic or electric devices such as lightening equipment,
security keys or security cards.
When the key is close to a magnetic or metal object or a battery. -

ECU
Immobilizer Indicator and Warning Lamp ▶
This indicator comes on when the ignition
key is communicating with the engine
control unit (during engine starting) and
goes out after starting the engine.
When turning the ignition key to ON
position, the ECU transmits the challenge
message to the immobilizer unit to verify
whether the key is valid. (1)
Only when the two signals are identical, it
recognizes the key as the authorized one and
transmits the positive message to the ECU.
The ECU allows the engine to be started. (6)
(7)
Do not drop or shock to the transponder in the key as it may be damaged.
With a damaged transponder, the engine cannot be started.
When you erase the code or register an extra key, let the owner attend on the site.
In any case, the immobilizer system cannot be removed from the vehicle. If you attempt to
remove it and damage the system, starting will be impossible, so never attempt to remove,
damage or modify it.
The remote engine starter cannot be installed on the vehicle equipped with the immobilizer
system. -

2. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial
engine start is made. This may cause the wiper blades to wear prematurely. Therefore, other
than rainy days, set the switch to the OFF position. Especially during the winter time, check if
the wiper blades are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the
windshield can be scratched and the wiper blades can wear prematurely. Use the wiper with the
washer fluid when the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of
the wipers. -
-
-
-
When cleaning the windshield over the sensor with damp clothes, the wiper may operate
suddenly. It could cause serious injury. Make sure to place the wiper switch to the OFF
position and ignition switch OFF when not in use.
Irregular operation (abrupt operation) ▶
Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to
work irregularly. Therefore, in this case, replace the wiper blade with a new one. -
