NOTICE: Do 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 vehicle to 2WD inspection mode.
d. Measure the oil pressure.
Oil pressure: 9.8 kPa (0.1 kgf-cm, 1.4 psi) or more
NOTICE: Be sure to cancel the inspection mode immediately after the oil pressure check is completed.
e. Install a new 0-ring and fluid pump cover plug.
