*: These components are included in control valve assembly.

CVT CONTROL SYSTEM : TCM

INFOID:0000000009759319

• The TCM consists of a microcomputer and connectors for signal

input and output and for power supply.

• The vehicle driving status is judged based on the signals from the

sensors, switches, and other control units, and the optimal tran-

saxle control is performed.

• For TCM control items, refer to 

TM-93, "CVT CONTROL SYSTEM

: System Description"

.

CVT CONTROL SYSTEM : ROM Assembly

INFOID:0000000009759320

• The ROM assembly   is installed to control valve.

• 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:0000000009759321

• The transmission range switch is installed to upper part of tran-

saxle case.

• The transmission range switch detects the selector lever position.
