ERASING OF CVT FLUID DEGRADATION LEVEL DATA
- TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if the transaxle assembly/control valve is replaced, it is necessary to erase the CVT fluid degradation level data recorded by TCM.
CHECKING CVT FLUID
The fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check procedure is as follows

- Check for fluid leakage.
- With the engine warmed up, drive the vehicle in an urban area. When ambient temperature is 20°C (68°F), it takes about 10 minutes for the CVT fluid to warm up to 50 to 80°C (122 to 176°F).
- Park the vehicle on a level surface.
- Apply parking brake firmly.
- With engine at idle, while depressing brake pedal, move shift selector throughout the entire shift range.
- Pull out the CVT fluid level gauge from the CVT fluid charging pipe after pressing the tab on the CVT fluid level gauge to release the lock.
- Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid level gauge rotating 180° from the originally installed position, then securely push the CVT fluid level gauge until it meets the top end of the CVT fluid charging pipe. CAUTION: When wiping away the CVT fluid level gauge, always use lint-free paper, not a cloth rag.
- Place the selector lever in "P" or "N" and check that the fluid level is within the specified range. CAUTION: When reinstalling CVT fluid level gauge, insert it into the CVT fluid charging pipe and rotate it to the original installation position until securely locked.
CVT FLUID CONDITION
Check CVT fluid condition.
Scheme 119
- If CVT fluid is very dark or smells burned, check operation of CVT. Flush cooling system after repair of CVT.
- If CVT fluid contains frictional material (clutches, brakes, etc.), replace radiator and flush cooler line using cleaning solvent and compressed air after repair of CVT. Refer to " «CLEANING»(ref-621391-S25488287802014061000000) ".
| Fluid status | Conceivable cause | Required operation |
|---|---|---|
| Varnished (viscous varnish state) | CVT fluid become degraded due to high temperatures. | Replace the CVT fluid and check the CVT main unit and the vehicle for malfunctions (wire harnesses, cooler pipes, etc.) |
| Milky white or cloudy | Water in the fluid | Replace the CVT fluid and check for places where water is getting in. |
| Large amount of metal powder mixed in | Unusual wear of sliding parts within CVT | Replace the CVT fluid and check for improper operation of the CVT. |
