SSTEM OUTLINE Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The electronically controlled transmission, however, electrically controls the governor pressure and lock-up through the solenoid valve. ontrol of the solenoid valve by the engine control module based on the input signals from each sensor makes smooth driving possible by shift selection for each is most appropriate to the driving conditions at that time.. GER SHIFT OPERTION uring driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions, based on input signals from the engine coolant temp. sensor to TERMINL THW of the engine control module and also the input signals to TERMINL SP+ of the engine control module from the vehicle speed sensor devoted to the electronically controlled transmission. urrent is then output to the electronically controlled transmission solenoid. When shifting to st speed, current flows from TERMINL S of the engine control module to TERMINL of the electronically controlled transmission solenoid to GROUN, and continuity to the no. solenoid causes the shift. For nd speed, current flows from TERMINL S of the engine control module to TERMINL of the electronically controlled transmission solenoid to GROUN, and from TERMINL S of the engine control module to TERMINL 8 of the electronically controlled transmission solenoid to GROUN. nd continuity to solenoid no. and no. causes the shift. For rd speed, there is no continuity to no. solenoid, only to no. causing the shift. Shifting into th speed (Overdrive) takes place when there is no continuity to the either no. or no. solenoid.. LOK-UP OPERTION When the engine control module judges from each signal that lock-up operation conditions have been met, current flows from TERMINL SL of the engine control module to TERMINL 7 of the electronically controlled transmission solenoid to GROUN, causing continuity to the lock-up solenoid and causing lock-up operation.. STOP LIGHT SW IRUIT If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINL STP of the engine control module, the engine control module operates and continuity to the lock-up solenoid is cut.. OERRIE IRUIT O/ main SW on When the O/ main SW is turned on, a signal is input to TERMINL OMS of the engine control module and engine control module operation causes gear shift when the conditions for overdrive are met. O/ main SW off When the O/ main SW is turned off, a signal is input into TERMINL OMS of the engine control module, and turns on the O/ off indicator light. This activates the EU, and the transmission system is controlled not to shift to overdrive. 5. /T OIL TEMP. WRNING When the /T fluid temp. sensor affixed to the transmission case detects that the fluid temp. is 50 (0 F) or more, the engine control module operates and the current flowing through the GUGE fuse flows to the /T oil temp. warning light to TERMINL OILW of the engine control module to GROUN, so that warning light lights up, informing that the /T oil temp. is high. When the /T oil temp. drops to 0 (8 F) or less, the engine control module stops operating and the warning light goes out. 00 RUNNER (EW5U) 9
