If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.PREPARATION BEFORE OPERATION (PART 2)
With CONSULT
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Confirm that the CVT fluid temper ature is in the following range.
With GST
1. Start the engine.
2. Set the CVT fluid to 10 °C (58° F) or more.
NOTE:
When the ambient temperature is 20 °C (68° F), the CVT fluid usually increases to 50 to 80 °C (122 to
176° F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 10
°C (58°F) or more?
YES >> GO TO 3.
NO >> 1. Warm the transaxle. 2. GO TO 3.
3.CHECK DTC DETECTION

Press the ATF changer hose all the way onto the charging
pipe until it stops.
21. Fill approximately 3 liter (2-5 /8 lmp qt) of the CVT fluid.
22. Remove the ATF changer hose and charging pipe, then install the drain plug.
NOTE:
Perform this work quickly because CVT fluid leaks.

CVT FLUID
• During adjustment of the CVT fluid level, check CO
NSULT so that the oil temperature may be main-
tained from 35 to 45 °C (95 to 113 °F).
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.
1. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104° F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
5. Lift up the vehicle.
6. Check that there is no CVT fluid leakage.
7. Remove the drain plug. Refer to TM-242, "
Removal and Installation".
8. Install the charging pipe set (KV311039S0) (A) into the drain plug hole.
CAUTION:
Tighten the charging pipe by hand.
9. Install the ATF changer hose (B) to the charging pipe. CAUTION:
Press the ATF changer hose all the way onto the charging
pipe until it stops.
10. Fill approximately 0.5 liter (1/2 lmp qt) of the CVT fluid.
11. Remove the ATF changer hose from the charging pipe, and check that the CVT fluid drains out from the charging pipe. If it
does not drain out, perform charging again.
CAUTION:
Perform this work with the vehicle idling.
12. When the flow of CVT fluid slows to a drip, remove the charging pipe from the oil pan.
13. Tighten the drain plug to the specified torque. Refer to TM-242, "
Removal and Installation".
CAUTION:
Never reuse drain plug gasket.
14. Lift down the vehicle.
15. Stop the engine.

Inspection and AdjustmentINFOID:0000000012431194
INSPECTION AFTER REMOVAL
Check oil pan for foreign material.
• If a large amount of worn material is found, clutch plate may be worn.
• If iron powder is found, bearings, gears, or clutch plates may be worn.
• If aluminum powder is found, bushing may be worn, or ch ips or burrs of aluminum casting parts may enter.
Check points where wear is found in all cases.
ADJUSTMENT AFTER INSTALLATION
Erase the CVT fluid deterioration data.
INSPECTION AFTER INSTALLATION
• When replacing control valve, perform "ADDITION AL SERVICE WHEN REPLACING CONTROL VALVE OR
TRANSAXLE ASSEMBLY". Refer to TM-127, "
Work Procedure".
• Check the CVT fluid level, condition and leakage.
