10. If the change of the fluid level is 5 mm (0.2 inch) or more, the air has not been
completely bled from the system. The air bleeding procedure must be repeated.

OIL PUMP PRESSURE TEST Required Special Tools:
MB990662: Power Steering Oil Pressure Gauge MB991548: Power Steering Oil Pressure Gauge Adapter (Pump Side) MB991549: Power Steering Oil Pressure Gauge Adapter (Hose Side)
1. Disconnect the pressure hose from the oil pump, and then connect special tools
MB991548
, MB990662 and MB991549.

2. Bleed air, 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
(122 - 140°F).
3. Start the engine and idle it at 700 +/- 100 r/min.
4. Fully close the shut-off valve of the pressure gauge and measure the oil pump
relief pressure to confirm that it is within the standard value range. Open it
again immediately after checking the pressure.
Standard value: 9.3 - 9.8 MPa (1,349 - 1,421 psi)
CAUTION: The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.

5. If it is not within the standard value, replace the oil pump.
6. Check whether or not the hydraulic pressure is the standard value when no-
load conditions are created by fully opening the shut-off valve of the pressure
gauge.
Standard value: 0.8 - 1.0 MPa (116 - 145 psi)
7. If it is not within the standard value, the probable cause is a malfunction of the
oil line or steering gear, so check these parts and repair as necessary.
8. Turn the steering wheel all the way to the left or right; then check the retention
hydraulic pressure.
Standard value: 9.3 - 9.8 MPa (1,349 - 1,421 psi)
9. If not the standard value, overhaul or replace the steering gear. Remeasure
fluid pressure.
10. Remove special tools MB991548, MB990662 and MB991549, and then tighten
the pressure tube flare nut to the specified torque.
Tightening torque: 15 +/- 3 N.m (11 +/- 2 ft-lb)
11. Bleed the system (Refer to POWER STEERING SYSTEM AIR
BLEEDING
).
POWER STEERING PRESSURE SWITCH CHECK Required Special Tools:
MB990662: Power Steering Oil Pressure Gauge MB991548: Power Steering Oil Pressure Gauge Adapter (Pump Side) MB991549: Power Steering Oil Pressure Gauge Adapter (Hose Side)
1. Disconnect the pressure hose from the oil pump, and then connect the special
tools MB991548, MB990662 and MB991549.
2. Bleed air, and then turn the steering wheel several times while the vehicle is
not movin

C (122 - 140°F).
3. The engine should be idling.
4. Disconnect the connector for the oil pressure switch, and place an ohmmeter at
the switch.
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: 18 - 2.4 MPa (261 - 348 psi)
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: 0.8 - 2.4 MPa (116 - 348 psi)
7. Remove the special tools MB991548, MB990662 and MB991549, and then
tighten the pressure tube flare nut to the specified torque.
Tightening torque: 15 +/- 3 N.m (11 +/- 2 ft-lb)
8. Bleed the system. (Refer to POWER STEERING SYSTEM AIR BLEEDING
).
