P Output Speed Sensor (Secondary Speed Sensor)
The shift pattern is changed in accordance with the throttle position when an unexpected signal is sent from
the output speed sensor (secondary speed sensor) to the TCM. The sport mode is inhibited, and the transaxle
is put in “D”.
Input Speed Sensor (Primary Speed Sensor)
The shift pattern is changed in accordance with the throttle position and secondary speed (vehicle speed)
when an unexpected signal is sent from the input speed sensor (primary speed sensor) to the TCM. The sport
mode is inhibited, and the transaxle is put in “D”.
PNP Switch
If an unexpected signal is sent from the PNP switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature Sensor
If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before
receiving the unexpected signal is maintained or the gear ratio is controlled to keep engine speed under 5,000
rpm.
Transmission Fluid Pressure Sensor A (Secondary Pressure Sensor)
 If an unexpected signal is sent from the transmission fluid pressure sensor A (secondary pressure sensor) to
the TCM, the secondary pressure feedback control is stopped and the offset value obtained before the non-
standard condition occurs is used to control line pressure.
 If transmission fluid pressure sensor A (secondary pressure sensor) error signal is inputted to the TCM, sec-
ondary pressure feedback control stops, but line pressure is controlled normally.
Pressure Control Solenoid A (Line Pressure Solenoid Valve)
If an unexpected signal is sent from the solenoid valve to the TCM, the pressure control solenoid A (line pres-
sure solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Pressure Control Solenoid B (Secondary Pressure Solenoid Valve)
If an unexpected signal is sent from the solenoid valve to the TCM, the pressure control solenoid B (secondary
pressure solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid Valve
If an unexpected signal is sent from the solenoid valve to the TCM, the torque converter clutch solenoid valve
is turned OFF to cancel the lock-up.
Ste p M oto r
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used just before the non-standard condition occurred.
CVT Lock-up Select Solenoid Valve
If an unexpected signal is sent from the solenoid valve to the TCM, the CVT lock-up select solenoid valve is
turned OFF to cancel the lock-up.
TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to the TCM. Normal status is restored when turning the ignition
switch OFF to ON after the normal power supply.

MECHANICAL SYSTEM
Component Description
INFOID:0000000003806353
Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the conventional
CVT and transmits it to the transaxle.
Oil pumpThe efficiency of pump discharge rate has been increased at low-rpm and optimized at high-rpm
by adopting a vane-type oil pump controlled by the engine. Discharged oil from oil pump is trans-
mitted to the control valve. It is used as the oil of primary and secondary pulley operation and the
oil of clutch operation and the lubricant for each part.
Planetary gear
Perform the transmission of drive power and the switching of forward/backward movement. Forward clutch
Reverse brake
Primary 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 star wheels are placed continuously and the belt is guided with the mul-
tilayer 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. Secondary pulley
Steel belt
Output gear
Reduction gear consists of primary deceleration (output gear and idler gear in pair) and second-
ary deceleration (reduction gear and final gear in pair). Each of them uses a helical 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

< FUNCTION DIAGNOSIS >[CVT: RE0F10A]
HYDRAULIC CONTROL SYSTEM
Normal Control
Optimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throt-
tle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revo-
lution speed, the brake signal, the PNP switch signal, the lock-up signal, the voltage, the target gear ratio, the
fluid temperature, and the fluid pressure.
Feedback Control
For the normal fluid control and the select fluid control, secondary pressure is detected for feedback control by
using a secondary pressure sensor to set a high-precision secondary pressure.

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch
OFF. Then wait at least 10 seconds before performing the next test.
Perform the following procedure to confirm the malfunction is eliminated after the repair.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “Data Monitor” mode for “TRANSMISSION”.
3. Start engine.
4. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
Is
“P0705 PNP SW/CIRC” detected?
YES >> Go to TM-213, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003806388
1.CHECK POWER SOURCE
1. Turn ignition switch OFF.
2. Disconnect PNP switch connector.
3. Turn ignition switch ON.
4. Check voltage between PNP switch vehicle side harness connector terminal and ground.
