2010 NISSAN LATIO brake fluid

CVT-40
< SERVICE INFORMATION >[RE0F08B]
TROUBLE DIAGNOSIS
The CVT fluid temperature rises in the range of 50 - 80
°C (122 - 176° F) during 10 minutes of driving.
3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special service tool: - (OTC3492)].
CAUTION:
When using the oil pressure gauge, be sure to u se the O-ring attached to the oil pressure detec-
tion plug.
4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, and then measure the line pressure at both idle and the stall speed.
CAUTION:
• Keep the brake pedal pressed all the way down duringmeasurement.
• When measuring the line pressure at the stall speed, refer
to "STALL TEST" .
6. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque below.
CAUTION:
• Do not reuse O-ring.
• Apply CVT fluid to O-ring.

• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom- eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indi cator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
