CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000009650087

DESCRIPTION

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit
ofthe main electronically controlled input/output parts is damaged.

OIL PRESSURE CONTROL SYSTEM : System Description

INFOID:0000000009650089

The hydraulic control mechanism consists of the oil pump directly driven by the engine, the hydraulic control
valve that controls line pressure and transmission, and the input signal line.

LINE PRESSURE AND SECONDARY PRESSURE CONTROL

• When an input torque signal equivalent to the engine driving force is transmitted from the ECM to the TCM,

the TCM controls the line pressure solenoid valve and secondary pressure solenoid valve.

• Highly accurate line pressure control and secondary pressure control reduces friction for improvement of

fuel economy.
