POWER STEERING OIL PRESSURE SWITCH
CHECK
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 - 60_C.
3. The engine should be idling.
4. Disconnect the connection of the connector for the oil
pressure switch, and set an ohmmeter in position.
5. Gradually close the shut-off valve of the pressure gauge
and increase the hydraulic pressure, then check whether
or not the hydraulic pressure that activates the switch
is the standard value.
Standard value: 1.8 - 2.4 MPa
6. Gradually open the shut-off valve and reduce the hydraulic
pressure; then check whether or not the hydraulic pressure
that deactivates the switch is the standard value.
Standard value: 1.0 - 2.4 MPa
7. Remove the special tools, and then tighten the pressure
hose to the specified torque.
Tightening torque: 18 ± 3 N·m
8. Bleed the system.
BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing
it with finger.
2. If the dust cover is cracked or damaged, replace the
