Repair Procedures: Removal
WARNING:
- Be sure to read and follow the "GENERAL SAFETY INFORMATION & 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 read and follow the "HIGH VOLTAGE SHUT-OFF PROCEDURES " before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
CAUTION:
- When the solenoid valve Diagnostic Trouble Codes (DTC) is on, perform the following procedure to replace it.
- Automatic transaxle is composed of delicate components. Be careful not to cause any damage on the component in the course of assembly and disassembly.
- Maintain clean condition so that foreign substance does not get into the automatic transaxle.
- Use a coated apron, latex gloves, and stainless tray to prevent foreign substance from getting into the transaxle.
- Automatic transaxle fluid (ATF) can be reused. Collect it using a clean 10-liter beaker.
- Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.
(Refer to General Information - "LIFT AND SUPPORT POINTS ")
- Shut off the high voltage circuit.
(Refer to Automatic Transaxle System - "REPAIR PROCEDURE ")
- Remove the under cover.
(Refer to Engine Mechanical System - "ENGINE ROOM UNDER COVER ")
- Drain the engine coolant.
(Refer to Engine Mechanical System - "COOLANT ")
- Drain the coolant of hybrid motor cooling system.
(Refer to Hybrid Motor System - "COOLANT ")
- Remove the Hybrid Power Control Unit (HPCU) assembly and tray.
(Refer to Hybrid control system - "REMOVAL ")
- Remove the ATF warmer.
(Refer to Automatic Transaxle Cooling System - "ATF WARMER ")
- Separate the air bleeder hose (A).
- Remove the drain plug (A) and reinstall the drain plug after draining ATF totally.
Drain plug tightening torque:
34.3 - 43.1 N.m (3.5 - 4.4 kgf.m, 25.3 - 31.8 lb-ft)
CAUTION:- Replace the gasket before reinstalling the drain plug.
- Remove the bracket (A) after loosening the bolts.
- Loosen the mounting bolts of the valve body cover (A).
Tightening torque:
12.7 - 13.7 N.m (1.3 - 1.4 kgf.m, 9.4 - 10.1 lb-ft)
CAUTION:- Be careful when removing the valve body cover because the remaining ATF remains in the valve body cover.
- Loosen the bolts and then removing the main harness (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
- Remove the solenoid valve support bracket (A) after loosening the bolts.
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
- Disconnect the connector (A) from the solenoid valve connector module.
- Loosen the solenoid valve connector module mounting bolts (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
- Disconnect the solenoid valve connector (A).
- Loosen the bolt and then removing the solenoid valve connector fixing clip (A).
- Put down the solenoid valve connector and then separate the solenoid valve connector (B) from the transaxle.
