constant vehicle speed controller in which control of the switch on the instrument panel makes it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal Set Operation When the main SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicator light in the combination meter Set Speed Control When the – SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is controlled Coast Control When the – SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to decelerate the vehicle Every time the – SET SW is turned on instantaneously, the vehicle speed is decelerated approximately 1.6 km/h Accel Control When the + RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to accelerate the vehicle Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approximately 1.6 km/h Resume Control When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control Manual Cancel Mechanism If any of the following signals is input during cruise control travelling, the cruise control is cancelled ∗ The stop lamp SW is turned on ∗ The CANCEL SW is turned on ∗ The main SW is turned off ∗ Gear is shifted from D position to other positions than D (A/T) ∗ Clutch pedal depresed (M/T) Auto Cancel Function If any of the following conditions is encountered, the cruise control is automatically cancelled ∗ The stop lamp SW wiring is faulty or short–circuited ∗ The vehicle speed signal is faulty ∗ The electronically controlled throttle malfunctions ∗ The actual vehicle speed becomes –16 km/h slower than the set speed ∗ The actual vehicle speed becomes slower than the minimum speed limit Overdrive Control Function Overdrive is sometimes cut off on gradients during cruise control driving When end of climbing gradient is determined by throttle opening degree information after overdrive is canceled, control is reset to overdrive condition after overdrive resetting timer operation Also, when overdrive is cut off during accelerator resuming control, control is reset to overdrive condition when accelerator resuming control is finished : Parts Location Code See Page Code A19 44 E7 E8 See Page Code D 44 J14 E 44 P1 C9 44 C14 44 J1

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 line pressure, throttle pressure, lock–up pressure and accumulator pressure etc through the solenoid valve The electronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response to the vehicle’s driving conditions and the engine condition detected by various sensors It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off Gear Shift Operation When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from the engine coolant temp sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL SP2+ of the engine control module At the same time, the throttle valve opening signal from the throttle position sensor is input to TERMINALS VTA1 and VTA2 of the engine control module as throttle angle signal Based on these signals, the engine control module selects the best shift position for the driving conditions and sends current to the electronically controlled transmission solenoid Line Hydraulic Pressure Control The engine control module adjusts the line hydraulic pressure to the optimal level by controlling TERMINAL SLT+ of the module according to the engine torque data This realizes the smooth gear shifting High Response Gear Shifting Control The engine control module performs the high response engine torque up control to control the ignition–timing lag as well as opening the electronic throttle when shifting down By doing this, the gear shifting is performed in a short period of time Moreover, the engine control module uses the orifice switching control, which optimizes the speed of applying and reducing the hydraulic pressure And it realizes the fine shifting condition by applying and reducing hydraulic pressure slowly when the gear shifting shock is important and quickly when the high response is required Clutch Hydraulic Pressure Control The engine control module controls the clutch operation in the optimal timing and with the best hydraulic pressure according to the engine torque data and the number of the clutch revolution Lock–Up and Flexible Lock–Up Control The engine control module carries out the lock–up control by controlling the TERMINAL SLU+ of the module according to the shift position, vehicle speed, throttle opening degree and running conditions The engine control module also steadily keeps applying the lock–up clutch a delicate slippage to improve the transmission efficiency (Fuel efficiency) of the torque converter Stop Lamp SW Circuit If the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of the engine control module The engine control module operates and cuts the current to the solenoid to release lock–up AI–Shift Control The engine control module judges whether the road is downslope or upslope by detecting the throttle opening degree or the vehicle’s speed Moreover it can expect the winding roads by detecting the turning condition of the vehicle The engine control module keeps unnecessary shifting up from the fourth gear from operating and carries out the automatic shifting down to the third gear in order to control the vehicle running according to the road conditions The engine control module also reads the driver’s intention during driving from his (her) accelerating operation and the running conditions of the vehicle As a result of that, ideal shifting patters for each driver are automatically selected without any switching operations : Parts Location Code See Page A19 E7 E8 C9 A 44 C10 B 44 D4 E1 A E2 Code 44 See Page

using mechanically controlled throttle hydraulic pressure, governor hydraulic pressure and lock–up hydraulic pressure The electronically controlled transmission, however, controls the line pressure and lock–up pressure etc electrically, through the solenoid valve The engine control module controls each solenoid valve based on the input signals from each sensor, which makes smooth driving possible by shift selection for each gear that is most appropriate to the driving conditions at that time Gear Shift Operation During 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 TERMINAL THW of the engine control module, and also the input signals to TERMINAL SPD of the engine control module from the vehicle speed sensor devoted to the electronically controlled transmission Current is then output to the electronically controlled transmission solenoid When shifting to 1st speed, the current flows from TERMINAL S1 of the engine control module to TERMINAL (B) of the solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL of the electronically controlled transmission solenoid to GROUND, and continuity to the No.1 and No.2 solenoid causes the shift For 2nd speed, the current flows from TERMINAL S1 of the engine control module to TERMINAL (B) of the solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL (B) of the solenoid to GROUND, and continuity to solenoid No.1 and No.2 causes the shift For 3rd speed, there is no continuity No.1 solenoid, only to No.2, causing the shift Shifting into 4th speed (Overdrive) takes place when there is no continuity to both No.1 and No.2 solenoid Stop Lamp SW Circuit If the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of the engine control module, the engine control module operates and continuity to the lock–up solenoid is cut AI–Shift Control The engine control module judges whether the road is downslope or upslope by detecting the throttle opening degree or the vehicle’s speed Moreover it can expect the winding roads by detecting the turning condition of the vehicle The engine control module keeps unnecessary shifting up from the fourth gear from operating and carries out the automatic shifting down to the third gear in order to control the vehicle running according to the road conditions The engine control module also reads the driver’s intention during driving from his (her) accelerating operation and the running conditions of the vehicle As a result of that, ideal shifting patters for each driver are automatically selected without any switching operations :
