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.

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. -

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.

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. -

4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor is
able to compensate the wear up to a specific level. Check the coupler attached surface of
windshield for porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage
from low sensitivity (Smark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wi
per switch “AUTO” position, the wiper operates one cycle

problem, go to diagnosis mode in STICS and check the terminal that receives signal from
wiper and communication lines between rain sensor unit and STICS. -
When the variable resistance knob is rotated by 4 stage from 0 stage without stoping, the
wiper operates one cycle. The wiper operates one cycle when changing the wiping stage (0
→ 1, 1 → 2, 2 → 3). -

Let the engine run for 1 to 2 minutes and
stop it. If the brake pedal stroke is
shortened as pumping the brake pedal,
the system is normal. If not, the system is
defective.
Depress the brake pedal several times with
engine off. If the brake goes down when
starting engine with pedal depressed, the
system is normal. If not, the system is
defective. 1.
2.
Depress the brake pedal when the engine
is running. If the pedal height is not
changed for 30 seconds after stopping the
engine, the system is normal. If not, the
system is defective. 3.
If the above three checks are OK, the system
is normal. If any condition is not met, check
the valve, vacuum hose and brake booster.
