ENGINE CONTROL SYSTEM
Ignition “OFF” ▶
4. INDUCTION SYSTEM
1) Throttle Valve Actuator
The throttle actuator is actuated by the Engine Control Module(ECM) according to the position
of the accelerator pedal position.
It has two potentiometers which signal the position of the throttle valve to the ECM to enable it
to recognize the various engine load states.
In the de-energized states the throttle valve position is determined to be spring capsule.
Ignition “ON” ▶
When the ignition S/W on the servo motor in the throttle actuator is operated by the ECM.
The throttle valve adopts a position in line with the coolant temperature.
In the closed throttle position, the servo motor controls engine speed by operating the throttle
valve further (greater mixture) or closing it further (reduced mixture), depending on coolant
temperature and engine load.
When this is done, the throttle valve can be closed further by the servo motor overcoming the
force of the spring capsule (mechanical end stop).
If the actuator is deenergized, the throttle valve is resting against the spring capsule.
Consequently, the throttle valve opening is a constant 10 ~ 12° approximately.
At no load, this produces an engine speed of about 1,800 rpmClosed Position ▶

3. ON-VEHICLE SERVICE
(1) Electronic system service precautions
Take care to avoid electronic brake control module (HECU) circuit overloading. In testing for
opens or shorts, do not ground or apply voltage to any circuit unless instructed to do so by the
diagnostic procedure. Test circuits only with a high-impedance multi-meter. Never remove o
r
apply power to any control module with the ignition switch in the ON position. Always turn the
ignition to the OFF position before removing or connecting battery cables, fuses or connectors.
(2) General service precautions
Disconnect the HECU connector before performing any vehicle welding work using an electric
arc welder. Do not attempt to disassemble any component designated as nonserviceable. The
hydraulic modulator and the HECU can be seperated. (There is however no access to repai
r
the each components.)
(3) Bleeding system
Replacement modulators are shipped already filled and bled. In normal procedures requiring
removal of the modulator, such as to replace the HECU, air will not enter the modulator, and
normal bleeding will be all that is needed.
If air enters the hydraulic modulator, or if an unfilled modulator is installed, use the brake
bleeding program in the scan tool to bleed the modulator. Manual bleeding of the hydraulic
modulator is not possible.
1) Service Precautions
Brake Fluid may irritate eyes and skin. In case of contact, take the following actions:
Eye contact - rinse thoroughly with water.
Skin contact - wash with soap and water.
Ingestion - consult a physician immediately. -
-
-
To help avoid personal injury due to poor braking. DO NOT Tap into the vehicle’s
brake system to operate a trailer brake system.
When fasteners are removed, always reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use the correct part number fastener
for is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners that are not reused, and those requiring thread-locking compound will be
called out. The correct torque values must be used when installing fasteners that require
them. If the above procedures are not followed, parts or system damage could result.

ABS SYSTEM
Service precautions ▶
Observe the following general precautions during any ABS/TCS service. Failure to adhere to
these precautions may result in ABS/TCS system damage.
Disconnect the EBCM harness connector before performing the electric welding procedures.
Carefully note the routing of the ABS/TCS wiring and wiring components during removal.
The ABS/ TCS components are extremely sensitive to EMI (eletromagnetic interference).
Proper mounting is critical during component service.
Disconnect the EBCM connector with the ignition OFF.
Do not hang the suspension components from the wheel speed sensor cables. The cables
may be damaged.
Do not use petroleum based fluids in the master cylinder. Do not use any containers
previously used for petroleum based fluids. Petroleum causes swelling and distortion of the
rubber components in the hydraulic brake system, resulting in water entering the system
and lowering the fluid boiling point. 1.

3. FUNCTIONS OF RK STICS
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.

STICS
Rain sensing operation point ▶
The wiper relay is turned on and the wiper motor runs one cycle when the ignition key is
turned to “ON” position (while the wiper switch is in “AUTO” position).
The wiper relay (LO) is turned on and the wiper motor runs one cycle when changing the
wiper switch to “AUTO” position from any other positions (while the ignition key is in
“ON” position). When the wiper switch is turned to “AUTO” position again from other
positions, the system drives the wiper relay (LO) to run the wiper motor one cycle only when
the rain sensor detects the “Rain Detected” signal. 1)
2)
Rain sensing sensitivity control ▶
The wiper relay is turned on and the wiper motor runs one cycle when the volume sensitivity is
increased (ex: from 0 to 1) (while the ignition key is in “ON” position, the wiper switch is
in “AUTO” position, and the wiper motor is in “Parked” position). However, the wiper
motor can be operated only when the rain sensor detects the “Rain Detected” signal.
* If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle.

Defective rain sensor ▶
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wipe
r
sensitivity is changed to 2 from 3 during receiving the malfunction signal (1) from the rain
sensor (while the ignition key is in “ON” position and the wiper switch is in “AUTO”
position). 1)
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper
sensitivity is changed to 3 from 4 during receiving the malfunction signal (2) from the rain
sensor (while the ignition key is in “ON” position and the wiper switch is in “AUTO”
position). 2)

(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. ·
