*: 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
.
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.
