STICS
(5) Auto Door Unlock (Crash Unlock)
For conventional vehicles, G-sensor in RK STICS generates “UNLOCK” signal when
collided over 15 km/h over vehicle speed. In this vehicle, the factory installed air bag module
transmits the collision signal to STICS to unlock the door.
The air bag collision signal cannot be accepted within 7 seconds after turning the ignition
key to “ON” position.

The “Unlock” control by air bag signal prevails over any “LOCK” or “UNLOCK”
control by other functions.
The “LOCK/UNLOCK” request by other functions will be ignored after/during the
output of “UNLOCK” by the air bag.
However, the door lock is controlled by other functions when IGN1 SW is “OFF” and
IGN2 SW is “OFF”.
If the door lock system outputs “LOCK” and “UNLOCK” simultaneously, only the
“LOCK” output can be activated.
Even though the “LOCK/UNLOCK” output is requested, the door lock system cannot
output “LOCK/UNLOCK” when all door lock switches are locked/unlocked.
Also, even though the “UNLOCK” output for the driver’s door is requested, the door
lock system cannot output “UNLOCK” when the driver’s door is unlocked. (1)

2) Speedometer
The speedometer indicates the vehicle speed by calculating the signals from the rear right
wheel speed sensor through ABS or ESP unit.
If the speedometer pointer vibrates, stands at a certain range or sounds abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be appeared when
the tire has uneven wear, different tire inflation pressures or different tire specifications.
Perform the speedometer test regarding the tolerance as described. However, it is not simila
r
simple work in field due to lack of measuring conditions such as test equipment and
preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer by
using a tester.
Check if the speedometer pointer is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer. 1.

The allowable tolerance increases when the tires are worn or the tire pressure is out of
specified range. -

4) Coolant Temperature Gauge
The coolant temperature gauge displays the coolant temperature with a pointer. The angle of
pointer that changes by coolant temperature is as shown below.
Measurement of coolant temperature sensor resistance
Measure the resistance between the terminal and the ground with an ohmmeter and replace i
f
the resistance is out of specified range.
Resistance value by coolant temperature:
20°C : 2449 Ω ±5 %
50°C : 826 Ω ±5 %
80°C : 321 Ω ±5 %
100°C : 112 Ω ±5 %
When the resistance value by coolant temperature is within the specified range, check
thermostat, water pump, radiator related coolant circuit for normal operation. Also, check the
wiring harnesses and connectors for proper connection.

RAIN SENSOR

The rain sensing wiper unit in this vehicle doesn’t control the wiper directly.
The rain sensing unit detects the amount of rain drops and sends the operating signal to
STICS, and STICS drives the wiper directly.
1. COMPONENTS OF RAIN SENSOR
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing
section(rain sensor mounting section on the
windshield)with photodiode. Rain sensing unit
Multifunction wiper switch:
AUTO and sensitivity control AUTO
: Wiper operates automatically by rain sensor
FAST <-------> SLOW
: Auto delay/Auto speed control. A position
that
can control sensitivity against rains on the
windshield and transmits wiping demand
signal accordingly.

At this moment, STICS determines the wiper operation mode
(washer, MIST, AUTO), then sends the information to the rain
sensor.

2. RAIN SENSOR OPERATION
The rain sensor is installed on the specific heat treated windshield that has minimum 13% of
transmittance rate with specified intensity of radiation. It is installed on the glass with a
adhesive of Sorepa.
It communicates with STICS and makes the wipers to operate automatically under the rain
sensing mode (multifunction switch wiper: AUTO mode).
The emitting section of the rain sensor unit emits infrared rays against the windshield and then
detects the amount of rain drops by receiving reflected rays with photodiode.
The sensing section on the windshield is located just above the center point between LED and
photodiode.

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 wiper switch “AUTO” position, the wiper operates
one cycle to remind a driver that the wiper switch is in “AUTO” position.
When the wiper switch is turned to “AUTO” from OFF, the wiper operates one cycle. It
always operates one cycle for the initial operation, however, the wiper does not operate
afterwards to prevent the wiper blade wear if not raining when turning the wiper switch to
“AUTO” from “OFF”. However, the wiper operates up to 5 minutes after rain stops.
If this function does not occur, check No. 2 terminal on the rain sensor. If any defective
cannot be found, check the wiper relay (LOW) for defective. 1)
2)
3)If the installed wiper brushes are out of specification (size and length), the rain sensing
area cannot be fully wiped. In this case, the rain sensor’s sensitivity could be
decreased and the wipers are not properly operated -
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not
any 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. -

4) Washer Coupled Wiper Function
Check the washer coupled wiper operation by pressing the washer switch.
5) Irregular Operations (Abrupt Operations)
6) Self Diagnosis
Position the wiper switch to “AUTO” position and rotate the variable resistance knob from
“FAST” toward “SLOW” by one step.
At this moment, check if the wiper operates one cycle.
The wiper operates when the windshield glass is excessively worn or scratched, the windshield
glass is not cleared wiped due to using worn wiper blade or different wiper blade, or the rain
sensor is not improperly installed.Check the sensor for coming off.
Check the rain sensor cover installation.
Check that the customer is familiar to how to control the wiper sensitivity. -
-
-
If the wiper blade cannot wipe the glass uniformly and clearly, the irregular operations could be
occurred. And, the wiper blade should be replaced with new one with same specifications. Check that the customer can select the sensitivity by selecting the variable resistance value
(stage 1 to stage 5), that is, the wiper sensitivity control value. And, also check whether the
sensitivity is selected to the highest value of FAST (stage 5).
Check the wiper blade for wear. -
▶Poor sensing
▶Poor sensor
Rotate the variable resistance knob toward “SLOW” by 2 more steps. At this moment,
check if the wiper operates one cycle.
The wiper operates when the sensor is defective.
