STICS Engine Compartment Fuse Box
STICS ▶
The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS,
and STICS drives the wiper directly. At this moment, STICS determines the wiper operation mode
(washer, MIST, AUTO), then sends the information to the rain sensor.
Auto Light Sensor and Rain Sensor Coupled Control ▶
Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost
LOW), the headlamps are turned on automatically. -
Night detected wiping: When the auto light control turns on the headlamps and the rain
sensor detects the rain, the wiper sensitivity is automatically increased by one level in
comparison with daytime.
(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.) -Wiper relay (HI)

7) Speed Sensitive INT Wiper
Calculates and converts the Intermittent interval automatically by obtaining the INT VOLUME
when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive mode as soon as turning the INT auto
switch to the "ON" position with the ignition key ON or turning the ignition key to the "ON"
position with the INT auto switch ON.
This applies to the vehicle without the rain sensor. -

Controls the wiper intermittent operation by the values from the vehicle speed and the setting

TCU ▶
TCU is located under the driver's seat and controls the operations of transmission.
TCU receives the ignition voltage and has three connectors (16-pin, 12-pin, 20-pin).
TCU receives input signals from certain transmission-related sensors, gear select lever and
inhibitor switch. TCU also uses these signals when determining transmission operating strategy.
TCU uses PCAN to communicate with other units. And, TCU communicates with engine ECU,
ESP unit, TCCU and instrument cluster through CAN lines to control the gear shifting and to
recognize the current gear position.
DSI M78 Automatic Transmission is based on the transmission in the vehicle with D20DT engine
for EURO III or EURO IV or EURO V.
Differences: changed some components (torque converter and torque converter housing, some
pinion gears, sun gear), increased torsional damping force.

1. OVERVIEW
The six speed automatic (M78) transmission
is available in two variants: four wheel drive
and two wheel drive.
The transmission has the following features:
Six Forward Speeds
One reverse gear
A torque converter with an integral converter lock-up clutch
Electronic shift and pressure controls
A single planetary gear-set
A double planetary gear-set
Two hydraulically controlled brake bands
Three multi-plate clutches
All hydraulic functions are directed by electronic solenoids to control: -

The transmission contains fully synthetic automatic transmission fluid (ATF) and is filled for life;
therefore it does not require periodic servicing.
Engine power reaches the transmission via a torque converter with integral converter lock-up
clutch.
The six forward gears and one reverse gear are obtained from a single planetary set, followed by
a double planetary set. This type of gear-set arrangement is commonly known as Lepelletier type
gear-set.
The automatic transmission is electronically controlled. The control system is comprised of the
following elements:
External transmission control unit (TCU)
Internal embedded memory module (EMM)
Input and output speed sensors
Valve body unit comprised of four on/off solenoid valves and six variable bleed solenoids

2) Cooling System
The transmission cooling system ensures rapid warm-up and constant operating temperature
resulting in reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient cooling and
lubrication to the transmission drivetrain in the event of a blockage in the transmission cooler.
Gear Shift ▶
Coastdown ▶
Torque Demand ▶ Transmission gear change is controlled by the TCU. The TCU receives inputs from various engine
and vehicle sensors to select shift schedules and to control the shift feel and torque converter
clutch (TCC) operation at each gear change
Coastdown downshifts occur at 0% accelerator pedal when the vehicle is coasting down to a
stop. To reduce the shift shock and to improve the shift feeling during downshift, TCU
electronically controls the transmission.
Torque demand downshifts occur (automatically) when the driver demand for torque is greater
than the engine can provide at that gear ratio. If applied, the transmission will disengage the TCC
to provide added acceleration.
