Component DescriptionINFOID:0000000003848923
Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the con-
ventional AT and transmits it to the transaxle.
Oil pumpThe adoption of a trochoidal oil pump with a flow control valve actuated directly by the
engine enables the sufficient discharge from an oil pump in the low-rpm range and the
adequate discharge adjustments in the high-rpm range.
Planetary gear
Perform the transmission of drive power and the switching of forward/backward move-
ment. Forward clutch
Reverse brake
Primary pulley It is composed of a pair of pulleys (the groove width is changed freely in the axial direc-
tion) and the steel belt (the steel star wheels are placed continuously and the belt is guid-
ed 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 pul-
ley. Secondary pulley
Steel belt
Output gear
Reduction gear consists of primary deceleration (output gear and idler gear in pair) and
secondary deceleration (reduction gear and final gear in pair). Each of them uses a he-
lical gear. Idler gear
Reduction gear
Final gear
Differential
Manual shaft
The parking rod rotates the parking pole and the parking pole engages with the parking
gear when the manual shaft is in “P” position. As a result the parking gear and the output
axis are fixed. Parking rod

WORK SUPPORT MODE
Display Item List
Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“−1”“−2”“OFF” can be selected by touching “UP”or “DOWN” on CONSULT-III screen.
However, do not select a mode other than “0” and “OFF”. Selecting “+1” or “−1” or “–2” may cause
irregular driveability.

CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.
SELF-DIAGNOSTIC RESULT MODE
Display Items List
Refer to TM-121, "DTC Index".
DATA MONITOR MODE
Display Items List
Diagnostic test mode Function
Work Support This mode enables a technician to adjust some devices faster and more accurately.
Self-Diagnostic Results Retrieve DTC from ECU and display diagnostic items.
Data Monitor Monitor the input/output signal of the control unit in real time.
CAN Diagnosis This mode displays a network diagnosis result about CAN by a diagram.
CAN Diagnostic Support Monitor It monitors the status of CAN communication.
Function TestThis mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For en-
gine, more practical tests regarding sensors/switches and/or actuators are available.
ECU Identification Display the ECU identification number (part number etc.) of the selected system.
Special Function Other results or histories, etc. that are recorded in ECU are displayed.
Item name Description

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “Data Monitor” mode for “TRANSMISSION”.
3. Start engine and maintain the following conditions for at least 10 minutes (total).
With GST
Follow the procedure “With CONSULT-III”.
Is
“P0710 ATF TEMP SEN/CIRC” detected?
YES >> Go to TM-50, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003848962
1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check resistance between TCM vehicle side harness connector terminals.
Is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 1)
1. Disconnect CVT unit connector.

TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signals. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000003848976
 The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-
cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.
 Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
 When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed shall not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
