Hybrid Transaxle System

HYBRID TRANSMISSION / TRANSAXLE: HYBRID TRANSAXLE SYSTEM: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. CHECK TRANSAXLE FLUID LEVEL
NOTICE:
- Insufficient or excessive amounts of transaxle oil may be the cause of some trouble.
- Place the vehicle on a level surface.
- Use genuine ATF WS.





(a) Remove the filler plug.
(b) Ensure that the transaxle oil level is within 0 to 5 mm (0 to 0.20 in.) of the filler plug hole.
NOTE: Recheck the transaxle oil level after driving the vehicle when exchanging oil.
HINT: Transaxle fluid quantity: 3.8 liters (4.0 US qts, 3.3 Imp. qts.)

(c) Check for leaks if the quantity of oil is low.
(d) Install the filler plug with a new gasket.
Torque: 39 Nm (400 kgf-cm, 29 ft-lbf)
2. INSPECT OIL PRESSURE
NOTE: Perform the test at normal operating oil temperature 50 to 80°C (122 to 176°F).

(a) Lift up the vehicle.





(b) Remove the fluid pump cover plug and install SST.
SST: 09992-00095
09992-00112
09992-00271
(c) Set the blower switch to HI.
(d) Turn the A/C switch on.
(e) Push the power switch with the brake pedal depressed to start the engine (start the hybrid system).
(f) Keeping the engine speed of 1,200 rpm, measure the oil pressure.
Standard oil pressure:
9.8 kPa (0.1 kgf/cm2, 1.4 psi) or more





(g) Install a new O-ring and fluid pump cover plug.
Torque: 7.4 Nm (75 kgf-cm, 65 in-lbf)
3. INSPECT SHIFT LEVER
(a) Inspect the shift lever operation with the hybrid system operating.




(1) Carry the key into the indoor electrical key oscillator detection area or insert the key in the key slot.
(2) Turn the power switch ON (READY ON) while depressing the brake pedal.
Check that the gear changes according to the shift operation pattern. If the check result is abnormal, replace the shift lever assembly.
HINT: The shift operation pattern in power switch ON (READY ON) (when the vehicle is stopped) is shown below.









(b) Turn the power switch OFF when the vehicle is stopped.





(c) Inspect the shift lever operation with the power switch's power mode ON (IG).
(1) Carry the key into the indoor electrical key oscillator detection area or insert the key in the key slot.





(d) Turn the power switch ON (IG) without depressing the brake pedal.
HINT: The power switch's power mode changes between OFF, ON (ACC) and ON (IG) each time the power switch is pressed.

(e) Check that the gear changes according to the shift operation pattern. If the check result is not as specified, replace the shift lever assembly.
HINT: The shift operation pattern with the power switch's power mode ON (IG) is shown below.
