The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper
sensitivity is changed to 2 from 1 during receiving the malfunction signal (3) from the rain
sensor (while the ignition key is in “ON” position and the wiper switch is in “AUTO”
position). Also, the wiper relay (LO) is turned on and the wiper motor runs one cycle when
the wiper sensitivity is changed to 2 from 1 during receiving the ground fixed or IGN fixed
signal from the rain sensor. 3)

STICS
(3) Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed
and INT VOLUME when the ignition switch is in “ON” position and the INT switch is in
“ON” position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch
to “ON” position with the engine running or starting the engine with the INT switch
positioned “ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -
-
-
2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the
table in next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

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
RODIUS 2005.07
8610-11
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.

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.
