COMPONENT PARTS

*: These components are included in control valve assembly.

CVT CONTROL SYSTEM : TCM

INFOID:0000000009019834

• 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-73, "CVT CONTROL SYSTEM : System Description"

.

CVT CONTROL SYSTEM : ROM Assembly

INFOID:0000000009019835

• The ROM assembly is installed to control valve.

Component

Function

IPDM E/R

The TCM receives the A/C compressor feedback signal via CAN communica-
tions from the IPDM E/R.

Combination meter

The TCM receives the overdrive cntrol switch signal via CAN communications 
from the combination meter.

ABS actuator and electric unit (control unit)

The TCM receives the following signals via CAN communications from the ABS 
actuator and electric unit (control unit).
• Vehicle speed signal
• VDC operation signal
• VDC malfunction signal

ECM

• For purposes including improving the feeling when shifting and preventing 

drops in engine speed, control signals are exchanged between the ECM and 
TCM, and real-time cooperative control is performed according to the vehicle 
driving conditions. (Engine and CVT integrated control)

- Engine and CVT integrated control signal
• The TCM receives the following signals via CAN communications from the 

ECM.

- Engine speed signal
- Accelerator pedal position signal
- Closed throttle position signal
• TCM sends and receives the following signals with ECM through CAN com-

munication to perform D position N idle control. 

- N idle instruction signal 

BCM

The TCM receives the following signals via CAN communications from the 
BCM.
• Stop lamp switch signal 
• Turn indicator signal

• The ROM assembly stores the calibration data (characteristic value) of each solenoid valve. TCM enables

accurate hydraulic control by obtaining the calibration data.

CVT CONTROL SYSTEM : Transmission Range Switch

INFOID:0000000009019836

• 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 Sensor

INFOID:0000000009019837

• The primary speed sensor is installed to side cover of transaxle.

• The primary speed sensor detects primary pulley speed.

• The primary 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, the faster the change cycle is”. The TCM judges the

rotating speed from the changing cycle of this pulse signal.

CVT CONTROL SYSTEM : Secondary Speed Sensor

INFOID:0000000009019838

• The secondary speed sensor is installed to side cover of transaxle.

• The secondary speed sensor detects secondary pulley speed.

• The secondary 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, the faster the change cycle is”. The TCM judges

the rotating speed from the changing cycle of this pulse signal.
