Repair Procedures: Removal
- 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 ")
- 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 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.
- Shut off the high voltage circuit.
(Refer to Automatic Transaxle System - " HIGH VOLTAGE SHUT-OFF PROCEDURES ")
- Remove the engine room 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 - " HPCU (HYBRID POWER CONTROL UNIT) ")
- 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:
33.3 - 43.1 N.m (3.4 - 4.4 kgf.m, 24.6 - 31.8 lb-ft)
- 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)
CAUTION:- Check for the looseness, poor connection, bending, corrosion, contamination, deterioration, or damage before reinstalling the solenoid valve connector.
- 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 bolts and then removing the input/output speed sensor (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
