[CVT: RE0F10B]

Precautions for Removing of Battery Terminal

INFOID:0000000010197929

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

Precaution for On Board Diagnosis (OBD) System of CVT and Engine

INFOID:0000000009752490

The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.

CAUTION:

• Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal

before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.

• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will

cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

• Be sure to route and secure the harnesses properly after work. Interference of the harness with a

bracket, etc. may cause the MI to light up due to a short circuit.

• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube

may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.

• Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and

ECM before returning the vehicle to the customer.

COMPONENT PARTS

• The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the

CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal volt-
age value.

CVT CONTROL SYSTEM : Secondary Pressure Sensor

INFOID:0000000009752504

• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
• When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is

deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Volt-
age is increased along with pressure increase.

• The line pressure solenoid valve is installed to control valve.
• The line pressure solenoid valve controls the pressure regulator valve. For information about the pressure

regulator valve, refer to

TM-167, "MECHANICAL SYSTEM : Component Description"

• The line pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].

NOTE:
• The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed

inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is
proportional to this pressing force.

• The N/H (normal high) produces hydraulic control when the coil is not energized.

• The torque converter clutch solenoid valve is installed to control valve.
• The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information

about the torque converter clutch control valve, refer to

TM-167, "MECHANICAL SYSTEM : Component

Description"

• The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type].

NOTE:
• The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed

inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is
proportional to this pressing force.

• The N/L (normal low) type does not produce hydraulic control when the coil is not energized.

CVT CONTROL SYSTEM : Lock-up Select Solenoid Valve

INFOID:0000000009752508

• The lock-up select solenoid valve is installed to control valve.
• The lock-up select solenoid valve controls the select switch valve. For information about the select switch

valve, refer to

TM-167, "MECHANICAL SYSTEM : Component Description"

• The lock-up select solenoid valve utilizes an ON-OFF solenoid valve.

NOTE:
• The only operations of the valve spool installed inside the coil are pressing or not pressing the ball which

seals the hydraulic supply section into the seat. This A/T uses N/L (normal low) type.

• When voltage is not applied to the coil, the force of the pilot pressure presses the ball against the seat,

stopping the pilot pressure at that point.

• When voltage is applied to the coil, the valve is pulled in the direction of the coil, disengaging the hydraulic

seal which the ball creates. This supplies pilot pressure to the operating locations.

CVT CONTROL SYSTEM : Step Motor

INFOID:0000000009752509

The step motor changes the step with turning 4 coils ON/OFF according to the signal from TCM. As a result,
the flow of line pressure to primary pulley is changed and pulley ratio is controlled.

CVT CONTROL SYSTEM : Manual Mode Switch

INFOID:0000000009752510

• The manual mode switch [mode select switch and position select switch (shift-up/shift-down)] is installed in

the CVT shift selector assembly.

• The mode select switch detects the position (the main shift gate side or manual shift gate side) of the selec-

tor lever and transmits a manual mode signal or a not manual mode signal to the combination meter. Then,
the TCM receives a manual mode signal or non-manual mode signal from the combination meter.

• The position select switch (shift-up) detects that the selector lever is shifted to the shift-up side of the manual

shift gate and transmits a manual mode shift up signal to the combination meter. Then, the TCM receives a
manual mode shift up signal from the combination meter.

• The position select switch (shift-down) detects that the selector lever is shifted to the shift-down side of the

manual shift gate and transmits a manual mode shift down signal to the combination meter. Then, the TCM
receives a manual mode shift down signal from the combination meter.

TRANSAXLE : Main Component Elements

INFOID:0000000009752517

TORQUE CONVERTER (WITH LOCK-UP FUNCTION)

In the same way as a conventional A/T, the torque converter is a system that increases the engine torque and
transmits the torque to the transaxle. A symmetrical 3-element, 1-stage, 2-phase type is used here.

OIL PUMP

Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to increase
efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume in high-speed
zone. Discharged oil from oil pump is transmitted to control valve. It is used as the oil of primary and second-
ary pulley operation, the oil of clutch operation, and the lubricant for each part.

FORWARD/REVERSE SELECTION UNIT

• A planetary gear type of forward/reverse selector mechanism is installed between the torque converter and

primary pulley.

• The power from the torque converter is input via the input shaft, operating a wet multi-plate clutch by means

of hydraulic pressure to switch between forward and reverse driving.

FINAL DRIVE AND DIFFERENTIAL

The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and sec-
ondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.
The lubrication oil is the same as the fluid (Genuine CVT fluid) which lubricates the entire transaxle.

STRUCTURE AND OPERATION

TRANSAXLE : Belt & Pulley

INFOID:0000000009752518

STRUCTURE

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 continuously 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 maintains necessary friction force. In this way, the
