CVT CONTROL SYSTEM : TCM

INFOID:0000000009177477

• 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-30, "CVT CONTROL SYSTEM

: System Description"

.

CVT CONTROL SYSTEM : Transmission Range Switch

INFOID:0000000009177479

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

saxle case.

• The transmission range switch detects the selector lever position.

CVT CONTROL SYSTEM : Input Speed Sensor

INFOID:0000000009177480

• The input speed sensor is installed to the front side of transaxle

case.

• The input speed sensor detects input shaft speed.

COMPONENT PARTS

• The input speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

judges the rotating body speed from the pulse signal.

CVT CONTROL SYSTEM : Primary Speed Sensor

INFOID:0000000009177481

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

• The primary speed sensor detects primary pulley speed.

• The primary speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

judges the rotating body speed from the pulse signal.
