NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Se lect Solenoid ValveINFOID:0000000009464191
• The select solenoid valve is installed to control valve.
• The select solenoid valve adjusts the tightening pressure of the forward clutch and reverse brake. For infor-
mation about the forward clutch and reverse brake, refer to TM-229, "TRANSAXLE : Component Descrip-
tion".
• The select solenoid valve uses the linear solenoid valve [N/H (normal high) type]. NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) type produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Torque Converter Clutch Solenoid ValveINFOID:0000000009464192
• The torque converter clutch solenoid valve is installed to control valve.
• The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information
about the torque converter clutch control valve, refer to TM-229, "TRANSAXLE : Component Description"
.
• The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type]. NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/L (normal low) type does not produce hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Line Pressure Solenoid ValveINFOID:0000000009464193
• The line pressure solenoid valve is installed to control valve.
• The line pressure solenoid valve controls the pressu re regulator valve. For information about the pressure
regulator valve, refer to TM-229, "TRANSAXLE : Component Description"
.
• The line pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type]. NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Paddle ShifterINFOID:0000000009464194
• The paddle shifter is installed to the steering.
• The paddle shifter transmits shift up and shift down switch signals to the combination meter. Then TCM
receives signals from the combination meter via CAN communication.
PADDLE SHIFTER FUNCTION
CVT CONTROL SYSTEM : Sh ift Position IndicatorINFOID:0000000009464195
TCM transmits shift position signal to combination mete r via CAN communication. The actual shift position is
displayed on combination meter according to the signal.

sition Function
D Although driving in manual mode is possible, selector lever automatically returns to D position after a certain period
of time because the selector lever is not fixed in manual mode.
DS Driving with the selector lever fixed in manual mode is possible.

5. Install transmitter (1) to road wheel while pressing at position (A).
CAUTION:
• Check that O-ring contacts horizontally with wheel.
• Check that the base of the valve stem is positioned in the
groove of the metal plate.
6. Install and tighten the valve stem nut to the specified torque. CAUTION:
Do not use power tool for installation.
7. Place wheel on turntable of tire machine. Ensure that transmitter
is 270 degrees from mounting/dismounting head.
NOTE:
Do not touch transmitter with mounting head.
8. Apply a suitable non-silicone lubricant to the tire outside bead. CAUTION:
• Do not use silicone lubricant. Use of silicone lubricant will
deteriorate the tire and wheel.
• Do not allow lubricant to make contact with transmitter.
9. Install the tire outside bead onto the road wheel as normal. NOTE:
If the tire is being reused, align the matching mark applied on
the tire with the position of the road wheel valve st em assembly for the purpose of road wheel and tire bal-
ance adjustment after installation. Ensure that the tire does not rotate relative to road wheel.
10. Install the valve core and inflate tire. CAUTION:
Do not reuse valve core.
11. Install the valve cap. CAUTION:
Do not reuse valve cap.
12. Balance the road wheel and tire assembly. Refer to WT-55, "Adjustment"
.
13. Install wheel and tire assembly in appropriate wheel position on vehicle. Refer to WT-55, "Adjustment"
.
NOTE:
If replacing the transmitter, then transmitter wake up operation must be performed. Refer to WT-25, "Work
Procedure".
14. Adjust neutral position of steering angle sensor. Refer to BRC-58, "Work Procedure"
