PRECAUTIONS [RE4F04B] PRECAUTIONS PFP:00001 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” ECS0095K The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision.
Page 11 PRECAUTIONS [RE4F04B] When connecting or disconnecting pin connectors into or from TCM, take care not to damage pin terminals (bend or break). Make sure that there are not any bends or breaks on TCM pin terminal, when connecting pin connectors.
Page 12: Service Notice Or Precautions
PRECAUTIONS [RE4F04B] Service Notice or Precautions ECS0095N FAIL-SAFE The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major electrical input/output device circuit is damaged. Under Fail-Safe, the vehicle always runs in third gear, even with a shift lever position of 1, 2 or D. The cus- tomer may complain of sluggish or poor acceleration.
Page 13 PRECAUTIONS [RE4F04B] *: For details of OBD-II, refer to EC-53, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" Certain systems and components, especially those related to OBD, may use a new style slide- locking type harness connector. For description and how to disconnect, refer to GI-24, "How to Check Terminal"...

CAUTION: Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner. Spray cooler cleaner only with adequate ventilation.
Page 22 A/T FLUID [RE4F04B] If one or more pieces of debris are found that are over 1mm (0.040 in) in size and/or peeled clutch facing material is found in the coffee filter, the fluid cooler is not serviceable. The A/T fluid cooler/radiator must be replaced and the inspection procedure is ended.

Page 37 OVERALL SYSTEM [RE4F04B] TCM FUNCTION The function of the TCM is to: Receive input signals sent from various switches and sensors. Determine required line pressure, shifting point, lock-up operation, and engine brake operation. Send required output signals to the respective solenoids.
Page 38: Control Mechanism
OVERALL SYSTEM [RE4F04B] Control Mechanism ECS0095X LINE PRESSURE CONTROL TCM has various line pressure control characteristics to meet the driving conditions. An ON-OFF duty signal is sent to the line pressure solenoid valve based on TCM characteristics. Hydraulic pressure on the clutch and brake is electronically controlled through the line pressure solenoid valve to accommodate engine torque.
Page 39 OVERALL SYSTEM [RE4F04B] The line pressure is reduced below 60°C (140°F) to prevent shifting shock due to low viscosity of automatic transaxle fluid when temperature is low. SAT006J Line pressure is increased to a maximum irrespective of the throttle opening when fluid temperature drops to −10°C (14°F).

Page 423: Line Pressure Control
A/T CONTROL SYSTEM [RE5F22A] Line Pressure Control ECS009CN The pressure control solenoid valve A controls linear line pressure by control signal from TCM and line pressure for clutches and brakes to reduce shift shock. This pressure control solenoid valve A controls the pressure regulator valve as the signal pressure and adjusts the pressure of the operating oil discharged from the oil pump to the line pressure most appropri- ate to the driving state.
Page 424 A/T CONTROL SYSTEM [RE5F22A] SPECIAL SHIFT MODE Upslope Mode When TCM detects upslope from load of engine torque and decrease of acceleration, this mode changes shift points in high-speed side according to the upslope degree and avoids busy shift of A/T. Downslope Mode When TCM detects downslope from increase of acceleration with accelerator full close, this mode operates moderate engine brake by changing shift points in high-speed side.
Page 425: Lock-Up Control
A/T CONTROL SYSTEM [RE5F22A] Lock-Up Control ECS009CP The torque converter clutch piston in the torque converter is engaged to eliminate torque converter slip to increase power transmission efficiency. The torque converter clutch control valve operation is controlled by the pressure control solenoid valve C, which is controlled by a signal from TCM, and the torque converter clutch control valve engages or releases the torque converter clutch piston.
Page 426 A/T CONTROL SYSTEM [RE5F22A] SMOOTH LOCK-UP CONTROL When shifting from the lock-up released state to the lock-up applied state, the current output to the pressure control solenoid valve C is controlled with the TCM. In this way, when shifting to the lock-up applied state, the torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Page 427: On Board Diagnostic (Obd) System
ON BOARD DIAGNOSTIC (OBD) SYSTEM [RE5F22A] ON BOARD DIAGNOSTIC (OBD) SYSTEM PFP:00028 Introduction ECS009CQ The A/T system has two self-diagnostic systems. The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in the ECM memory but not the TCM memory.
Page 428 ON BOARD DIAGNOSTIC (OBD) SYSTEM [RE5F22A] If the DTC is being detected currently, the time data will be “0”. SAT015K If a 1st trip DTC is stored in the ECM, the time data will be “1t”. SAT016K Freeze Frame Data and 1st Trip Freeze Frame Data The ECM has a memory function, which stores the driving condition such as fuel system status, calculated load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle speed at the moment the ECM detects a malfunction.

Page 434: How To Perform Trouble Diagnosis For Quick And Accurate Repair
TROUBLE DIAGNOSIS [RE5F22A] How To Perform Trouble Diagnosis For Quick and Accurate Repair ECS009CX INTRODUCTION The TCM receives a signal from the vehicle speed signal, throttle position sensor (accelerator pedal position sensor) or PNP switch and provides shift control or lock-up control via A/T solenoid valves. The TCM also communicates with the ECM by means of a signal sent from sensing elements used with the OBD-related parts of the A/T system for malfunction-diagnostic purposes.
