DESCRIPTION OF CONSTRUCTION AND OPERATION
ACTIVE STABILITY CONTROL SYSTEM (ASC)35C-24
Traction control operation
ASC-ECU receives various kinds of information from
the engine ECU, steering wheel sensor, G and yaw
rate sensor, and wheel speed sensor. When
ASC-ECU determines that the driving wheel is slip
-
ping, it suppresses the wheel slippage. At this time,
ASC-ECU controls the brake fluid pressure of the
driving wheel determined to be slipping so that the
torque is transferred to another driving wheel. The operations of suction valve, cut valve, and solenoid
valve are basically the same as that of the stability
control. ASC-ECU and the engine ECU communi
-
cate with each other via CAN bus line. When the
accelerator pedal is depressed too far, the signal
requesting the engine output reduction is sent to the
engine ECU so that the TCL controllability can be
secured.

CVT
CONTINUOUSLY VARIABLE TRANSMISSION (CVT)23-2
CVT
GENERAL INFORMATIONM2231000100165
The F1C1A transmission is adopted for the CVT.
This transmission is basically the same as conven
-
tional transmission.
The ATF warmer (ATF cooler) is adopted.
