Bleed the air, and then start the engine and turn the steering wheel several times so that the fluid temperature can rise to approximately 50-60°C (122-132°F) operating temperature.
Increase the engine speed to 1000 +/- 100 RPM.
Close the shut-off valve of the special tool and measure the fluid pressure to confirm that it is within the standard value range.
Standard value
1. Relief pressure: 5.9 MPa (60 kg-cm² , 853 psi)
  CAUTION: Do not keep the shut-off valve on the pressure gauge closed for more than ten seconds.
2. If the fluid pressure is not within the standard value range, overhaul the oil pump.
3. Remove the special tools, and tighten the pressure hose to the specified torque.
  Tightening torque 55-65 Nm (550-650 kg.cm, 40.6-47.9 lb.ft)
4. Bleed the system.
