SIGNAL PATH
• When a overdrive control switch signal is input to the combination meter, the combination meter transmits
the overdrive control switch signal to the TCM via CAN communication.
• When all of the following conditions are satisfied, t he TCM transmits a O/D OFF indicator signal to the com-
bination meter via CAN communication. The combination meter turns ON the O/D OFF indicator lamp on the
combination meter, according to the signal.
- TCM receives overdrive control switch signal via CAN communication from combination meter.
- Selector lever: D position

TCM transmits shift position signal to combination meter via CAN communication. The actual shift position is
displayed on combination meter according to the signal.
CVT CONTROL SYSTEM : Malfunc tion Indicator Lamp (MIL)INFOID:0000000012431008
The malfunction indicator lamp (MIL) is located on the combination
meter.
The MIL will illuminate when the ignition switch is turned ON without
the engine running. This is a bulb check.
When the engine is started, the MIL should turn off. If the MIL
remains illuminated, the on board diagnostic system has detected an
engine system malfunction.
For details, refer to EC-57, "

Mechanism
It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt
(the steel plates are placed conti
nuously and the belt is guided with the multilayer steel rings on both sides).
The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive
status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.
Steel belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒ The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divided by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.
Pulley gear shifting operation
• Pulley gear shifting operation The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine
load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation
pressures of the primary pulley and the secondary pulle y, and controls the pulley groove width. Along with
change of the pulley groove width, the belt contact radi us is changed. This allows continuous and stepless

Part name Function
Torque converter It is composed of the cover converter, turbine assembly, stator, pump impeller assem-
bly, etc. It increases the engine torque and transmits the power to the transaxle.
Oil pump Through the oil pump drive chain, it uses the vane oil pump driven by the engine. It gen-
erates necessary oil pressure to circulate fluid and to operate the clutch and brake.
Counter gear set The power from the torque converter is transmitted to the primary pulley through the
counter drive gear and the counter driven gear.
Belt & pulley (Continuously variable transmis-
sion) It is composed of the primary pulley, secondary pulley, steel belt, etc. and the mecha-
nism performs shifting, changes the gear ratio and transmits the power with oil pressure
from the control valve.
Auxiliary gearbox (stepped transmission) It is composed of the planetary gear, multi-disc clutch, multi-disc brake, etc. and the
mechanism performs shifting (1-2 gear shifting and reverse) with oil pressure from the
control valve.
Reduction gear set Conveys power from the transmission mechanism to the reduction gear and the final
gear.
Parking mechanism When the shift lever is changed to P position, the mechanism fixes the parking gear (in-
tegrated with the reduction gear) and the fixes the output shaft.
Control valve Controls oil pressure from the oil pump to the pressure suitable for the line pressure
control system, shift control system, lock-up control system and lubrication system.
Pressure regu lator valve Adjusts the discharge pressure from the oil pump to the optimum pressure (line pres-
sure) corresponding to the driving condition.
Torque converter regulator valve Adjusts the feed pressure to the torque converter to the optimum pressure correspond-
ing to the driving condition.
Pilot valve Adjusts line pressure and produces a constant pressure (pilot pressure) necessary for
activating each solenoid valve.

FLUID COOLER & FL
UID WARMER SYSTEM
FLUID COOLER & FLUID WARMER SYSTEM : System DescriptionINFOID:0000000012431015
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer (1) is installed on the front part of transaxle
assembly.
• When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high.
CVT Fluid Cooler (Water-cooling)
• The CVT fluid cooler (water-cooling) is installed in the radiator side tank (right side).
• CVT fluid is cooled by engine coolant.
SHIFT LOCK SYSTEM
Manual valve Distributes the clutch and brake operation pressures (pilot pressure) corresponding to
each shift position.
High clutch/reverse brake switching valve Switches the circuit for the high clutch and the reverse brake.
Torque converter clutch control valve It is operated with the torque converter clutch solenoid valve and it adjusts the tighten-
ing pressure and non-tightening pressure of the torque converter clutch piston of the
torque converter.
Primary pressure control valve It is operated with the primary pressure solenoid valve and adjusts the feed pressure to
the primary pulley.

INPUT/OUTPUT SIGNAL TABLE
SYSTEM DESCRIPTION
• CVT detects the vehicle driving status from switc hes, sensors and signals, and controls the vehicle so that
the optimum shift position and shift timing may always be achieved. It also controls the vehicle to reduce
shift and lockup shock, etc.
• Receives input signals from switches and sensors.
• Sends the output signal necessary for operation of solenoid valves, and evaluates the line pressure, shift timing, lockup operation, engine brake performance, etc.
• If a malfunction occurs on the electric system, activate the fail-safe mode only to drive the vehicle.
