• TCM selects “BLIPPING CONTROL” or “NORMAL SHIFT CONTROL” according to the gear position, the
selector lever position, the engine torque and the speed when accelerating by pedal depression.
• Engine speed control demand signal is transmitted from TCM to ECM under “BLIPPING CONTROL”.
• ECM synchronizes the engine speed according to the engine speed control demand signal.

INPUT/OUTPUT SIGNAL CHART
*: This signal is transmitted via CAN communication line.
SYSTEM DESCRIPTION
ASC (Adaptive Shift Control)
It automatically selects the shift pattern (such as road environment and driving style) suitable for the various
situations so as to allow the vehicle to be driven efficiently and smoothly.
For example. .
• When driving on an up/down slope
