Automatic Transaxle System

2007 > 2.7L V6 GASOLINE >
Electronic Control System
DESCRIPTION
The electronic control system used in the new generation auto transaxle is far superior to the previous systems. This
system is able to adopt a variable shift pattern for smooth and problem free shifting.
A solenoid valve is applied to each of the clutches and brakes and is independently controlled. Feedback control and
correction control is performed in all gears as well as utilization of mutual control system to increase shift feeling.
The torque converter damper clutch uses a partial lock up and full lock - up system. An additional control method called
the HIVEC system (neural network) is adopted to increase shift feeling.

ELECTRIC CONTROL LOCATION
The TCM(PCM) is located on the intake manifold in the engine room.

OPERATING COMPONENTS AND FUNCTIONS
SensorFunction
Input shaft speed sensor Detect turbine speed at UD retainer
Output shaft speed sensor Detect T/F drive gear speed at T/F driven gear (4A/T)
Crank angle sensor Detect engine speed
TPS(Gasoline) Throttle opening ratio by potentiometer
Air conditioner switch A/C load by thermister
Inhibitor switch Select lever position by contact switch
Brake switch Brake pedal position
Vehicle speed sensor Detect vehicle speed by speedometer driven gear
Sport mode switch Sport mode On/Off signal

Sport mode up- shift switchSport mode up- shift signal
Sport mode downshift switch Sport mode downshift signal
Request of torque reduction Send the request of torque reduction to ECM
ABS - ECM, Engine ECM In case of CAN communication
Sports Mode
Sports Mode Switch
Sports mode allows the manual up- shift and downshift with the accelerator pedal is depressed. The prompt response
and shift would be obtained due to the continuous shifting without cutting of driving power. The shifting time is also
decreased about 0.1sec during up- shift, 0.2sec during downshift. As the selector lever is pushed upward or downward
one time, the gear is up shifted or downshifted by one gear.

Controller Area Network (CAN)
Previously, for different computers in the vehicle to share the same information, each signal required a different pin
and wiring. However, with the introduction of a CAN system, only two lines are required to achieve the same function.
The information is in digital format. This method does not use an integrated ECM.

Input signals to TCM(PCM) through ‘CAN communication’
- Engine rpm, TPS signal
- A/CON signal, Engine coolant temperature
- Quantity of intake airflow, Vehicle speed
- Shift holding signal (FTCS ON)
Output signals from TCM(PCM) through ‘CAN communication’
- Request signal for torque reduction
- ATF temperature, TCM(PCM) type, TCM(PCM) error or not
- Damper clutch ON, OFF / Gear position
