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.

Overdrive control switch
TM-64, "CVT CONTROL SYSTEM : Overdrive Control Switch"
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.
