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)"

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.
