AT3 AUTOMATIC TRANSMISSION OPERATION V03468 AT4 AUTOMATIC TRANSMISSION OPERATION AT5 AUTOMATIC TRANSMISSION OPERATION AT6 AUTOMATIC TRANSMISSION OPERATION AX01A0M HYDRAULIC CONTROL SYSTEM The hydraulic control system is composed of an oil pump, valve body, solenoid valves, accumulators, clutches and brakes, as well as the fluid passages which connect all of these components. Based on the hydraulic pressure created by the oil pump, the hydraulic control system governs the hydraulic pressure acting on the torque converter clutch, clutches and brakes in accordance with the vehicle driving conditions. The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to operate the shift valves, and change the gear shift position. The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lockup clutch of the torque converter clutch. The No.4 solenoid valve is operated by signals from the ECM to control the engagement speed and reduce gear shift shock. V04973 AT7 AUTOMATIC TRANSMISSION OPERATION AT0KY06 ELECTRONIC CONTROL SYSTEM General The electronic control system for the A340E automatic transmission provides extremely precise control of the gear shift timing and lockup timing in response to driving conditions as sensed by various sensors located throughout the vehicle and in response to the engine's running condition. At the same time, the ECM control reduces vehicle squat when the vehicle starts out and gear shift shock. The electronic control system is also equipped with a self diagnosis system which diagnoses malfunctions of electronically controlled components and warns the driver, and a failsafe system which makes it possible for the vehicle to continue functioning when a malfunction occurs. Construction The electronic control system can be broadly divided into three groups; the sensors, ECM and actuators. V05702 AT8 AUTOMATIC TRANSMISSION OPERATION SYSTEM DIAGRAM No. 7 6 5 4 3 2 1 Cruise Control ECU O/D Main Switch RPM Sensor Stop Light Switch Throttle Position Sensor Park/Neutral Position Switch Pattern Select Switch Components This ECU prevents the transmission from shifting into O/D and prohibits lockup control when the vehicle's speed drops below the cruise control set speed parameter. Prevents upshift to the O/D gear if the O/D main switch is off. Detects the throttle valve opening angle. Detects if the brake pedal is depressed. Detects the shift lever position. Detects the engine speed. Function Selects the Power mode or the Normal mode for shift and lockup timing. ARRANGEMENT OF COMPONENTS AUTOMATIC TRANSMISSION OPERATION AT9 AT10 AUTOMATIC TRANSMISSION OPERATION 8 No.1 and No.2 Vehicle Speed Sensor Detects the vehicle speed. Ordinarily, transmission control uses signals from the No.2 vehicle speed sensor, and the No.1 vehicle speed sensor is used as a backup. 9 O/D Direct Clutch Speed Sensor Engine Coolant Temp. Sensor ECM Detects the input shaft speed from 1st gear to 3rd gear. Detects the engine coolant temperature. Control the engine and transmission actuators based on signals from each sensor. 10 11 12 No.1 and No.2 Solenoid Valves Control the hydraulic pressure applied to each shift valve, and control the gear position and timing. Controls the hydraulic pressure applied to the back chamber of the accumulator and smooths the engagement of clutches and brakes during shifting. Controls the hydraulic pressure applied to the lockup clutch and controls lockup timing. 13 No.4 Solenoid valve (For accumulator back pressure modulation) No.3 Solenoid valve (For lockup control) 14 15 O/D OFF Indicator Light Blinks and warns the driver, while the O/D main switch is pushed in, when the electronic control circuit is malfunctioning.

"X" mark means "O/D OFF" light never blinks. *2: "O" marks means the ECM memorizes the malfunction code if the ECM detects the diagnostic code detection condition. *3: This indicates items for which "2 trip detection logic" is used. With this logic, when a logic malfunction is first detected, the malfunction is temporarily stored in the ECM memory. If the same case is detected again during the second drive test, this second detection causes the O/D OFF light to blink. The 2 trip repeats the same mode twice. (However, the IG switch must be turned OFF between the 1st trip and 2nd trip.) HINT: S If the malfunction returns to normal while a malfunction warning is being output, the O/D OFF indicator light stops blinking and goes off. However, the diagnostic trouble code is retained in memory until it is cleared from memory. S If the diagnosis system output a diagnostic trouble code even though the O/D OFF indicator was not blinking, there is intermittent trouble. Check all the connections in the circuits corresponding to that code. S Codes 42, 62, 63 and 64 are limited to short or open circuits in the electrical system comprised of the solenoids, wire harnesses, and connectors. The ECM is unable to detect mechanical trouble (sticking, for example) in the solenoid valves. S If the speed sensors No.1 and No.2 happen to fail simultaneously, the ECM will neither alert the driver by blinking the O/D OFF indicator nor record any diagnostic trouble code. It will, however, decide that the vehicle can be driven only in 1st and none of the other gears, shifting upward will then be prohibited.

AT64 AUTOMATIC TRANSMISSION TROUBLESHOOTING DTC 46 No. 4 Solenoid Valve Circuit (For Accumulator Back Pressure Modulation) CIRCUIT DESCRIPTION The No. 4 solenoid valve controls the hydraulic pressure acting on the brakes and clutches of the planetary gear units when gears are shifted and does smooth gear shifting. The ECM determines optimum operating pressure according to the signals from the throttle position sensor,speed sensor and O/D clutch speed sensor and controls the volume of current flow to the solenoid valve. The amount of electric current to the solenoid is controlled by the (*) duty ratio of ECM output signals, causing momentary change to the hydraulic pressure acting on the clutches during gear shifting. When the duty ratio is high, the hydraulic pressure acting on the clutches is low. (*) Duty Ratio The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then DTC No. DTC Detection Condition All conditions below are detected for 1 second or more.

AT68 AUTOMATIC TRANSMISSION TROUBLESHOOTING DTC 61 No. 2 Vehicle Speed Sensor Circuit CIRCUIT DESCRIPTION The No. 2 vehicle speed sensor detects the rotation speed of the transmission output shaft and sends signals to the ECM. The ECM determines the vehicle speed based on these signals. An AC voltage is generated in the No. 2 vehicle speed sensor coil as the rotor mounted on the output shaft rotates, and this voltage is sent to the ECM. The gear shift point and lock-up timing are controlled by the ECM based on the signals from this vehicle speed sensor and the throttle position sensor signal. If the No. 2 speed sensor malfunctions, the ECM uses input signals from the No. 1 vehicle speed sensor as a back-up signal. DTC No. DTC Detection Condition All conditions below are detected 500 times or more continuously.

Check and repair harness and connector between ECM and No. 2 vehicle speed sensor (See page IN-29). AT71 AUTOMATIC TRANSMISSION TROUBLESHOOTING DTC 62, 63 No. 1, No. 2 Solenoid Valve Circuit CIRCUIT DESCRIPTION Shifting from 1st to O/D is done in combination with ON and OFF of the No. 1 and No. 2 solenoid valves controlled by ECM. If an open or short circuit occurs in either of the solenoid valves, the ECM controls the remaining normal solenoid to allow the vehicle to be operated smoothly (Fail safe function). Fail Safe Function If either of the solenoid valve circuits develops a short or an open, the ECM turns the other solenoid ON and OFF to shift the gear positions shown in the table below. If both solenoids malfunction, the hydraulic control is not made electronically and can only be operated manually. Manual shifting as shown in the following table must be done.

AT84 AUTOMATIC TRANSMISSION TROUBLESHOOTING Stop Light Switch Circuit CIRCUIT DESCRIPTION The purpose of this circuit is to prevent the engine from stalling, while driving in lockup condition, when brakes are suddenly applied. When the brake pedal is operated, this switch sends a signal to ECM. Then the ECM cancels operation of the lockup clutch while braking is in progress. WIRING DIAGRAM AT85 AUTOMATIC TRANSMISSION TROUBLESHOOTING INSPECTION PROCEDURE 1 C Check operation of stop light. Check if the stop lights go on and off normally when the brake pedal is operated and released. OK NG Check stop light signal. Check and repair stop light circuit. 2 P 1. 2. Connect a voltmeter to the terminals TT and E1 of the DLC2. Turn ignition switch ON. Fully depress the accelerator pedal until the voltmeter indicates 8 V and hold it. Remove the park/neutral position switch (See page AT17). C 1. 2. OK NG OK Proceed to next circuit inspection shown on matrix chart (See page AT56). 3 OK Check harness and connector between ECM and stop light switch (See page IN29). NG Repair or replace harness and connector. Check and replace ECM. AT86 AUTOMATIC TRANSMISSION TROUBLESHOOTING Pattern Select Switch Circuit CIRCUIT DESCRIPTION The ECM memory contains the shift programs for the NORMAL and POWER patterns, 2 position, and L position and the lockup patterns. Following the programs corresponding to the signals from the pattern select switch, the park/neutral position switch and other various sensors the ECM switches the solenoid valves ON and OFF, there by controlling the transmission gear change and the lockup clutch operation. WIRING DIAGRAM AT87 AUTOMATIC TRANSMISSION TROUBLESHOOTING INSPECTION PROCEDURE 1 Check voltage between terminal P of ECM connector and body ground. P 1. 2. C Connect the Check Harness A to the ECM (See page EG256). Turn ignition switch ON. Measure voltage between terminal P of the ECM connector and body ground when the pattern select switch is set to the PWR (POWER) position and NORM (NORMAL) position. OK Hint The ECM uses the normal pattern signal if the power signal is not input. NG OK Check pattern select switch. Proceed to next circuit inspection shown on matrix chart (See page AT56). 2 P C Disconnect the pattern select switch connector. Measure resistance between terminals 1 and 2 of the pattern select switch connector when the select switch is set to PWR and NORM positions. OK OK NG Replace pattern select switch. 3 OK Check harness and connector between battery and pattern select switch, ECM and pattern select switch (See page IN29). NG Repair or replace harness and connector. Check and replace ECM. AT88 AUTOMATIC TRANSMISSION TROUBLESHOOTING O/D Main Switch & O/D OFF Indicator Light Circuit CIRCUIT DESCRIPTION The O/D main switch contacts go off when the switch is pushed in and come on when it is pushed out. In O/D main switch OFF position, the O/D OFF indicator lights up, and the ECM prohibits shifting to overdrive. The ECM also causes the O/D OFF indicator light to blink when a malfunction is detected. In this case, connecting the terminals in the DLC1 or DLC2 can display the malfunction code. WIRING DIAGRAM AT89 AUTOMATIC TRANSMISSION TROUBLESHOOTING INSPECTION PROCEDURE 1 Check operation of O/D Main Switch. C 1. 2. Turn ignition switch ON. Check "O/D OFF" light when O/D main switch is pushed in to ON. OK C OK "O/D OFF" light goes off. 3. Check "O/D OFF" light when O/D main switch is pushed again, to OFF. "O/D OFF" light lights up. Hint If the "O/D OFF" light blinks when the O/D main switch is pushed in to ON, a malfunction is occurring in the system. Check the Diagnostic trouble code. OK NG Go to step 4. 2 Check voltage between terminal OD2 of ECM connector and body ground. P 1. 2. C OK Connect the Check Harness A to the ECM (See page EG256). Turn ignition switch ON. Check voltage between terminal OD2 of ECM connector and body ground. NG OK Proceed to next circuit inspection shown on matrix chart (See page AT56). 3 OK Check harness and connector between O/D OFF indicator light and ECM (See page IN29). NG Repair or replace harness and connector. Check and replace ECM. AT90 AUTOMATIC TRANSMISSION TROUBLESHOOTING 4 Check OD Main Switch. C 1. 2. Disconnect O/D main switch connector. Measure resistance between terminals 1 and 2 of O/D main switch connector. OK OK NG Replace O/D Main Switch. Check and replace combination meter (See page BE75). AT91 AUTOMATIC TRANSMISSION TROUBLESHOOTING O/D Cancel Signal Circuit CIRCUIT DESCRIPTION While driving with cruise control activated, in order to minimize gear shifting and provide smooth cruising, up hill overdrive may be prohibited temporarily in some conditions. The Cruise Control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels overdrive shifting until these signals are discontinued. (For details, see the Cruise Control section). WIRING DIAGRAM AT92 AUTOMATIC TRANSMISSION TROUBLESHOOTING INSPECTION PROCEDURE 1 Check voltage between terminal OD1 of ECM connector and body ground. P 1. 2. C OK Connect the Check Harness A to the ECM (See page EG256). Turn ignition switch ON. Measure voltage between terminal OD1 of the ECM connector and body ground. Voltage: 46V NG OK Proceed to next circuit inspection shown on matrix chart (See page AT56). 2 Check voltage between terminal OD of Cruise Control ECU harness side connector and body ground. P 1. Disconnect Cruise Control ECU connector. 2. Turn ignition switch ON. C OK Measure voltage between terminal OD of Cruise Control ECU harness side connector and body ground. Voltage: 46V NG OK Check and replace Cruise Control ECU. 3 OK Check harness and connector between Cruise Control ECU and ECM (See page IN29). NG Repair or replace harness and connector.
