COMPONENT DESCRIPTION
No. Component Function TCM TM-16, "CVT CONTROL SYSTEM : TCM"
ECM• For purposes including improving the feeling when shifting speeds and
preventing drops in engine speed, control signals are exchanged be-
tween the ECM and TCM, and real-time cooperative control is performed
according to the vehicle driving conditions. (Engine and CVT integrated
control)

COMPONENT PARTS
*: These components are included in control valve assembly.
CVT CONTROL SYSTEM : TCMINFOID:0000000009463963
• The vehicle driving status is judged based on the signals
from the sensors, switches, and other control units,
and the optimal transaxle control is performed.
• For TCM control items, refer to TM-30, "CVT CONTROL SYSTEM : System Description"
.
CVT CONTROL SYSTEM : Transmission Range SwitchINFOID:0000000009463964
• The transmission range switch is installed to upper part of transaxle case.
• The transmission range switch detects the selector lever position.
CVT CONTROL SYSTEM : Primary Speed SensorINFOID:0000000009463965
• The primary speed sensor is installed to side cover of transaxle.
• The primary speed sensor detects primary pulley speed.
• The primary speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM
judges the rotating body speed from the pulse signal.
CVT CONTROL SYSTEM : Output Speed SensorINFOID:0000000009463966
• The output speed sensor is installed to back side of transaxle.
• The output speed sensor detects final gear speed.

• The output speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body
speed which is “The higher the rotating body speed is, t he faster the change cycle is”. The TCM judges the
rotating speed from the changing cycle of this pulse signal.
CVT CONTROL SYSTEM : Input Speed SensorINFOID:0000000009463967
• The input speed sensor is installed to the front side of transaxle case.
• The input speed sensor detects input shaft speed.
• The input speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM
judges the rotating body speed from the pulse signal.
CVT CONTROL SYSTEM : CVT Fluid Temperature SensorINFOID:0000000009463968
• The CVT fluid temperature sensor is installed to control valve.
• The CVT fluid temperature sensor detects CVT fluid temperature in oil pan.

TORQUE CONVERTER (WITH LOCK-UP FUNCTION)
In the same way as a conventional A/T, the torque c onverter is a system that increases the engine torque and
transmits the torque to the transaxle. A symmetr ical 3-element, 1-stage, 2-phase type is used here.
OIL PUMP
Utilizes a vane-type oil pump that is driven by the engi ne 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 contro l 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 me chanism is installed between the torque converter and
primary pulley.
• The power from the torque converter is input via the i nput 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 steel belt
(the steel plates are placed conti nuously and the belt is guided with the multilayer steel rings on both sides).

19. Repeat steps 8 to 18 (one time).
20. Tighten the drain plug to the specified torque. Refer to TM-186, "Exploded View"
.
21. Remove the overflow plug.
22. Install the charging pipe set (KV311039S0) into the overflow plug hole. CAUTION:
Tighten the charging pipe by hand.
23. Install the ATF changer hose to the charging pipe. CAUTION:
Press the ATF changer hose all the way onto the charging pipe until it stops.
24. Fill approximately 3 liter (2-5/8 lmp qt) of the CVT fluid.
25. Remove the ATF changer hose and charging pipe, then install the overflow plug. NOTE:
Perform this work quickly because CVT fluid leaks.
26. Lift down the vehicle.
27. Start the engine.
28. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
29. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35 °C (95 °F) to 45 °C (113 °F).
30. Lift up the vehicle.
31. Remove the overflow plug and confirm that the CV T fluid is drained from the overflow plug hole.
CAUTION:
Perform this work with the vehicle idling.
NOTE:
If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.
32. When the flow of CVT fluid slows to a drip, tighten the overflow plug to the specified torque. Refer to TM-
186, "Exploded View".
CAUTION:
Never reuse O-ring.
33. Lift down the vehicle.

CAUTION:
• During adjustment of the CVT fluid level, check CO NSULT so that the oil temperature may be main-
tained from 35 to 45 °C (95 to 113 °F).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.
1. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104 °F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE: CVT fluid : Refer to
TM-212, "General Specification"
