CVT CONTROL SYSTEM : TOW Mode Indicator Lamp

INFOID:0000000009177494

• TOW mode indicator lamp is positioned on the combination meter. 

• TOW mode indicator lamp is ON when set to the tow mode. 

CVT CONTROL SYSTEM : Shift Position Indicator

INFOID:0000000009177495

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 : Malfunction Indicator Lamp (MIL)

INFOID:0000000009177496

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-26, "Malfunction Indicator Lamp (MIL)"

.

SHIFT LOCK SYSTEM

Overdrive control switch is pressed 
when the selector lever is in the “D” po-
sition and the OD OFF indicator lamp is 
ON.

OFF

Selector lever is shifted to other position 
when the selector lever is at “D” position 
and the OD OFF indicator lamp is ON.

Component

Function

Stop lamp switch

• The stop lamp switch turns ON when the brake pedal is depressed.
• When the stop lamp switch turns ON, the shift lock solenoid is energized.

Shift lock release button

Forcibly releases the shift lock when pressed.

Shift lock solenoid

It operates according to the signal from the stop lamp switch and moves the lock lever.

Park position switch

It detects that the selector lever is in “P” position.

STRUCTURE AND OPERATION

TRANSAXLE : Transaxle Mechanism

INFOID:0000000009177501

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.

PLANETARY GEAR

• 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.

Operation of Planetary gear

BELT & PULLEY

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the chain belt

.The groove width changes according to wrapping radius of chain 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.

Chain belt

The chain belt consists of approximately 150 locker pins   and
1,000 link plates  . Chains are rotated by locker pins sandwiched by

pulleys. This produces tension difference in chains among pulleys.

Accordingly, the power is transferred by the tension.

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.
