LINE PRESSURE CONTROL : System Description
SYSTEM DIAGRAM

DESCRIPTION
Highly accurate line pressure control (secondary pressure control) reduces friction for improvement of fuel economy.
Normal Oil Pressure Control
Appropriate line pressure and secondary pressure suitable for driving condition are determined based on the accelerator pedal position, engine speed, primary pulley (input) speed, secondary pulley (output) speed, vehicle speed, input torque, stop lamp switch signal, transmission range switch signal, lock-up signal, power voltage, target shift ratio, oil temperature and oil pressure.
Secondary Pressure Feedback Control
In normal oil pressure control and oil pressure control in shifting, highly accurate secondary pressure is determined by detecting the secondary pressure using a oil pressure sensor and by feedback control.

Vehicle Dynamic Control (VDC) system (if so equipped)
The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC System helps to perform
the following functions:
Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive w ...

Description
ECM receives input speed sensor signal from TCM via the CAN communication
line. ECM uses this signal for
engine control.
