ADDITIONAL SERVICE WHEN RE PLACING TRANSAXLE ASSEMBLY
DescriptionINFOID:0000000009464012
Perform the following work after the transaxle assembly is replaced.
ERASING AND WRITING TCM DATA• TCM performs accurate control by retrieving data (inher ent characteristic value) of each solenoid. For this
reason, after replacing transaxle assembly, it is nec essary to erase data stored in TCM and write new data.
ERASING OF CVT FLUID DEGRADATION LEVEL DATA • TCM records the degradation level of the CVT fluid calc ulated from the vehicle driving status. Therefore, if
the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by
TCM.
Work ProcedureINFOID:0000000009464013
1.CHECK THE SERIAL NUMBER (PART 1)
Write down the serial number of new transaxle assembly.
>> GO TO 2.
2.CHECK THE SERIAL NUMBER (PART 2)
1. Turn ignition switch ON.
2. Insert the attached CD into CONSULT.
3. Select “Work Support” in “TRANSMISSION”.
4. Select “WRITE IP CHARA - REPLACEMENT AT/CVT”.
5. Check that the serial number displayed on CO NSULT screen and those written in the memo agree.
CAUTION:
Never perform writing procedure.
6. Go back to MENU of “Work Support”.
>> GO TO 3.
3.INITIALIZE TCM
1. Set parking brake.
2. Select “ERASE MEMORY DATA”.
3. Touch “Start” according to the instructions on the CONSULT screen.
Is
“COMPLETED” displayed?
YES >> GO TO 4.
NO >> Turn ignition switch OFF and wait for a mi nimum of 10 seconds then perform the work again.

CAUTION:
• Always use shop paper. Never use shop cloth.
• Replace a drain plug gasket with new ones at the fi nal stage of the operation when installing.
• Use caution when looking into the drain hole as there is a risk of dripping fluid entering the eye.
• After replacement, always pe rform CVT fluid leakage check.
1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
2. Select “FLUID TEMP” and confirm t hat the CVT fluid temperature is 40°C (104 °F) or less.
3. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
4. Lift up the vehicle.
5. Remove the drain plug and drain the CVT fluid from the oil pan. Refer to TM-186, "Exploded View"
.
6. Install the drain plug to oil pan. CAUTION:
Drain plug gasket use the old one.
7. Remove the overflow plug from converter housing.
8. Install the charging pipe set (KV311039S0) (A) into the overflow 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 3 liter (2-5 /8 lmp qt) of the CVT fluid.
11. Remove the ATF changer hose and charging pipe, then install the overflow plug.
NOTE:
Perform this work quickly because CVT fluid leaks.
12. Lift down the vehicle.
13. Start the engine.
14. While depressing the brake pedal, shift the selector leve r to the entire position from “P” to “DS”, and shift it
to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
15. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35°C (95 °F) to 45 °C (113 °F).
16. Stop the engine.
17. Lift up the vehicle.
18. Remove the drain plug, and then drain CVT fluid from oil pan. CVT fluid : Refer to
TM-212, "General Specification"
.
Fluid capacity : Refer to TM-212, "General Specification"

26. Lift down the vehicle.
27. Start the engine.
28. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
29. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35 °C (95 °F) to 45 °C (113 °F).
30. Lift up the vehicle.
31. Remove the overflow plug and confirm that the CV T fluid is drained from the overflow plug hole.
CAUTION:
Perform this work with the vehicle idling.
NOTE:
If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.
32. When the flow of CVT fluid slows to a drip, tighten the overflow plug to the specified torque. Refer to TM-
186, "Exploded View".
CAUTION:
Never reuse O-ring.
33. Lift down the vehicle.

AdjustmentINFOID:0000000009464015
CAUTION:
• 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).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• 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 “DS”, and shift it to the “P” position.
NOTE: CVT fluid : Refer to
