Be sure to read and follow the “General Safety Information
and Caution” before doing any work related with the high voltage
system. Failure to follow the safety instructions may result in serious
electrical injuries.
•
Be sure to shut off the high voltage circuit according to the
“High Voltage Shut-off Procedures” before doing any work related
with the high voltage system to avoid serious electrical injuries.
1.
Shut off the high voltage circuit.
( Refer to Automatic Transaxle System - "High Voltage Shut-off Procedure")
2.
Remove the under cover (A).
Tightening torque :
7.8 ~ 11.8 N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7 lb-ft)
3.
Drain the coolant of hybrid motor cooling system.
( Refer to Hybrid Motor System - "Coolant")
4.
Drain the coolant of engine & transaxle cooling system.
(Refer to Engine Mechanical System - "Coolant ")
5.
Remove the hybrid power control unit assembly.
( Refer to Hybrid Control System - "HPCU (Hybrid Power Control Unit)"
6.
Remove the duct (A).
Tightening torque:
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
7.
Remove the air cleaner assembly.
(1)
Disconnect the breather hose (A).
(2)
Disconnect the air intake hose (B) and then remove the air cleaner assembly (C).
Tightening torque:
Hose clamp bolt:
2.9 ~ 4.9 N.m (0.3 ~ 0.5 kgf.m, 2.2 ~ 3.6 lb-ft)
Air cleaner assembly bolts:
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
•
When installing the air intake hose, the plate of the hose clamp must be in line with the stopper of the hose.
•
When installing the air intake hose, the center of the mark of hose must be in line with the throttle body rib.
8.
Remove the hybrid power control unit (HPCU) tray (A).
Be careful not to damage other system or parts when removing the transaxle assembly.
Installation
1.
Install in the reverse order of removal.
•
If install the new transaxle, remove the hanger bracket (A) and then install the transaxle.
(Does not need to be re-installed)
•
If the oil seal on the transaxle is damaged and fluid is
leaking, replace the oil seal . When installing the new oil seal, use
the specialized tool (oil seal installer: 09452-3D100).
•
Perform the procedures below after replacing the transaxle.
1)
Refill the automatic transaxle with fluid.
(Refer to Hydraulic System - "Fluid")
2)
Refill the engine & transaxle system with coolant.
(Refer to Engine Mechanical System - "Coolant ")
3)
Refill the hybrid motor cooling system with coolant and then perform the air bleeding using the GDS.
(Refer to Hybrid Motor System - "Coolant")
4)
Clear the diagnostic trouble codes (DTC) using the GDS. Even
though disconnecting the battery negative terminal, the DTCs will not be
cleared. So, be sure to clear the DTCs using the GDS.
5)
Reset the automatic transaxle adaptive values using the GDS.
6)
Perform the resolver sensor calibration using the GDS.
(Refer to Hybrid Motor System - "Resolver Sensor")
7)
Perform the clutch pressure sensor calibration using the GDS.
(Refer to Hybrid Control System - "Clutch Pressure Sensor")
8)
Perform the TCM adaptive values learning procedure.
(Refer to Automatic Transaxle Control System - "Repair Procedures")
Removal 1. Disconnect the brake fiuid level switch connector, and remove the reservoir cap. 2. Remove the brake fluid from the master cylinder reservior with a syringe. Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it off immediately ...
