Purpose\/Function<\/p>\n

\u2022 The TCM detects the vehicle conditions and performs calculations and processing based on input information from each type of sensor and switch.<\/div>\n
\u2022 Outputs control signals to each solenoid valve so that each type of control is optimally implemented according to the vehicle conditions.<\/div>\n

Main control content<\/p>\n<\/th>\n<\/tr>\n<\/thead>\n

\n
Shift point control<\/div>\n<\/td>\n
\n
Automatic shift control<\/div>\n
(D position)<\/div>\n<\/td>\n
\n
Driving mode<\/div>\n<\/td>\n
\n
Normal mode<\/div>\n<\/td>\n
\n
\u2022 Normal mode selected using drive selection<\/div>\n
\u2022 Performs automatic shift corresponding to vehicle speed and accelerator pedal depression amount<\/div>\n<\/td>\n<\/tr>\n
\n
SPORT mode<\/div>\n<\/td>\n
\n
\u2022 SPORT mode selected using drive selection<\/div>\n
\u2022 Performs automatic shifting corresponding to vehicle speed and accelerator pedal depression amount<\/div>\n
\u2022 Lower gear is selected than while in the Normal mode<\/div>\n<\/td>\n<\/tr>\n
\n
Active Adaptive Shift (AAS) mode<\/div>\n<\/td>\n
\n
\u2022 Unnecessary shift up is suppressed for several seconds by maintaining the gear corresponding to the operation speed at which the accelerator pedal is released<\/div>\n
\u2022 The optimum gear on the low vehicle-speed side is selected and shift down is executed corresponding to the operation force at which the brake pedal is depressed<\/div>\n
\u2022 During cornering, shift up is suppressed in preparation for acceleration after cornering<\/div>\n
\u2022 In regions of high elevation, the optimum gear is selected corresponding to the environment<\/div>\n
\u2022 The slope is estimated in the TCM to select the appropriate gear for ascent and descent<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 When SPORT mode is selected, the AAS selects a lower gear compared to when normal mode is selected, and maintains it for a longer period of time<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/td>\n<\/tr>\n
\n
High ATF temperature mode<\/div>\n<\/td>\n
\n
\u2022 Controls engine torque when the ATF temperature is high<\/div>\n<\/td>\n<\/tr>\n
\n
Low engine coolant temperature mode<\/div>\n<\/td>\n
\n
\u2022 If the engine coolant temperature is low, a gear lower than when in normal mode is selected<\/div>\n<\/td>\n<\/tr>\n
\n
Direct mode (with steering shift switch)<\/div>\n<\/td>\n
\n
\u2022 When the steering shift switch is operated while driving with the selector lever in the D position, the gear position may temporarily switch<\/div>\n<\/td>\n<\/tr>\n
\n
Manual shift control<\/div>\n
(M position)<\/div>\n<\/td>\n
\n
\u2022 When M position is selected, manual shifting is prioritized according to the driver\u2019s shift up\/shift down operation<\/div>\n<\/td>\n<\/tr>\n
\n
Shift pressure control<\/div>\n<\/td>\n
\n
Line pressure control<\/div>\n<\/td>\n
\n
\u2022 Controls line pressure with high accuracy and fine control corresponding to engine load conditions and vehicle driving conditions<\/div>\n<\/td>\n<\/tr>\n
\n
Direct electric shift control<\/div>\n<\/td>\n
\n
\u2022 Performs direct, electronic control of clutch engagement pressure appropriate to engine load conditions and vehicle driving conditions<\/div>\n<\/td>\n<\/tr>\n
\n
Learning control<\/div>\n<\/td>\n
\n
\u2022 Learns engine performance changes and transaxle deterioration over time to optimally correct clutch engagement pressure<\/div>\n<\/td>\n<\/tr>\n
\n
Torque converter clutch (TCC) control<\/div>\n<\/td>\n
\n
\u2022 Based on adoption of full range TCC control, active TCC control directly after acceleration from stop<\/div>\n
\u2022 By gradually engaging\/disengaging TCC piston, shock during operation is reduced<\/div>\n
\u2022 Implements TCC control when accelerator pedal is fully closed for improved fuel economy and emission performance<\/div>\n<\/td>\n<\/tr>\n
\n
Engine-transaxle integration control<\/div>\n<\/td>\n
\n
\u2022 Optimally controls engine output torque when shifting<\/div>\n
\u2022 Calculates optimum clutch engagement pressure according to engine output torque<\/div>\n<\/td>\n<\/tr>\n
\n
On-board diagnostic system<\/div>\n<\/td>\n
\n
\u2022 Main part of transaxle control includes self-diagnosis function. In case of malfunction, automatic transmission warning light illuminates to alert driver, and DTC is stored in TCM<\/div>\n
\u2022 When transaxle malfunction is determined resulting from on-board diagnostic test, system control is switched to prevent any dangerous situation while driving<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
