2. Disconnect the transaxle harness connectors.
3. Disconnect the CVT oil warmer water hoses from engine side. Refer to TM-199, "WATER HOSE :
Removal and Installation".
4. Remove the transaxle to engine and engine to transaxle bolts.
5. Remove the CVT fluid charging pipe.
6. Separate the engine from the transaxle assembly. Refer to EM-84, "Removal and Installation"
.
NOTE:
Using paint, put matching marks on the drive plate and torque converter when removing the torque con-
verter to drive plate nuts.
7. Remove transmission bracket.
INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Write down the serial number of the new transaxle assembly.
CAUTION:
• When replacing an engine or tr ansaxle you must make sure any dowels are installed correctly during
re-assembly.
• Improper alignment caused by missing dowels m ay cause vibration, oil leaks or breakage of driv-
etrain components.
• Do not reuse O-rings or copper sealing washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-62, "Removal and Installa-
tion".
• After converter is installed to drive plate, rota te crankshaft several turns to check that CVT rotates
freely without binding.
• When installing the CVT to the engine, align the ma tching mark on the drive plate with the matching
mark on the torque converter.
When installing the CVT to the engine, attach the bolts in accor-
dance with the following standard.
• (A) : Transaxle assembly to engine assembly.
• (B) : Engine assembly to transaxle assembly.

On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000009464176
The TCM and ECM have an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to
warn the driver of a malfunction causing emission deterioration.
CAUTION:
• Be sure to turn the ignition switch OFF and di sconnect the battery cable from the negative terminal
before any repair or inspection work. The open/s hort circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

REMOVAL
• Rotate bayonet ring counterclockwise. Pull out CVT unit har-
ness connector upward and remove it.
INSTALLATION
1. Align marking on CVT unit harness connector terminal with marking on bayonet ring. Insert CVT unit harness connector.
2. Rotate bayonet ring clockwise.
3. Rotate bayonet ring clockwise until marking on CVT unit har- ness connector terminal body is aligned with the slit on bayo-
net ring as shown in the figure (correctly fitting condition).

PRECAUTIONS
• Securely align marking (A) on CVT unit harness connec-
tor terminal body with bayonet ring slit . Then, be care-
ful not to make a half fit cond ition as shown in the figure.
• Never mistake the slit of bayonet ring for other dent por- tion.

CVT CONTROL SYSTEM : Protection Control
INFOID:0000000009464206
The TCM becomes the protection control status temporar ily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM has the following protection control.

Control
When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
Limits engine output when a wheel spin occurs in any of right and left drive wheels.
Vehicle behavior in
control If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
a certain degree.
Normal retu rn condi-
tion Wheel spin convergence returns the control to the normal control.
Control Engine output is controlled according to a vehicle speed while reversing the vehicle.
Vehicle behavior in
control Power performance may be lowered while reversing the vehicle.
Normal retu rn condi-
tion Torque returns to normal by positioning the selector lever in a range other than “R” position.
Control
When the CVT fluid temperature is high, the gear shift permission maximum revolution and the maximum
torque are reduced than usual to prevent increase of the oil temperature.
Vehicle behavior in
control Power performance may be lowered, compared to normal control.
Normal retu rn condi-
tion The control returns to the normal control when CVT fluid temperature is lowered.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOST
IC (OBD) SYSTEM
DescriptionINFOID:0000000009464211
This is an on board diagnosis system which records diagnosis information related to the exhaust gases. It
detects malfunctions related to sensors and actuators. The malfunctions are indicated by means of the mal-
function indicator lamp (MIL) and are stored as DTC in the ECU memory. The diagnosis information can be
checked using a diagnosis tool (GST: Generic Scan Tool).
Function of OBDINFOID:0000000009464212
The GST is connected to the diagnosis connector on t he vehicle and communicates with the on-board control
units to perform diagnosis. The diagnosis connector is the same as for CONSULT. Refer to GI-51, "Function
and System Application".
