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.

CAUTION
Do not ground accessories directly to
the battery terminal. Doing so will bypass
the variable voltage control system
and the vehicle battery may not
charge completely.
Use electrical accessories with the engine
running to avoid discharging the

CVT Fluid cooler system
Cleaning
Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT
fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can be trapped or be deposited
in the CVT fluid cooler. This
debris can contaminate th ...
