6.

With the engine idling, check the fluid level.

7.

Stop the engine.

8.

Wait for a few minutes, re-check the fluid level.

maximum fluid level rising height: 5 mm (0.20 in)

9.

If problems are detected, bleed the power steering
system. Refer to

7.2.8.7

.

10. Re-check the fluid level height.

7.2.8.3 Steering Fluid Pressure Inspection

FE07-1017b

1.

Disconnect the power steering pump assembly outlet
pipe. Refer to

7.2.8.6

Power Steering Outlet Pipe

Replacement

.

2.

Install the hydraulic pressure detection tool as shown in
the graphic.

Note

At the beginning of the inspection, the tool valve
should be at open position.

3.

Bleed the power steering system. Refer to

Power

Steering System Bleeding

.

4.

Preheat the power steering fluid, start the engine and let
the engine run at idle.

5.

Rotate the steering wheel from right to left and then rotate
back and forth several times, so that the fluid temperature
rise.

Preheat the fluid temperature to: 75-80 °C (167-176 ºF)

6.

Keep the engine at idle, close the tool valves, observe the
pressure gage readings and take notes.

Minimum hydraulic: 6,400 kPa (928 psi)
If the fluid pressure is too low, then the power steering
pump assembly is damaged, it needs to be Replaced.

Warning!

Special tool valves closing time can not exceed 5s,
otherwise the fluid temperature becomes too high
causing damage to the power steering pump
assembly.

Maintain the engine speed between 1,000 rpm and 3,000
rpm, measure the fluid pressure.

Hydraulic pressure difference: 490 kPa (71 psi) or less

Note

Do not turn the steering wheel.

If the fluid pressure difference is too great, the power
steering pump flow control valve assembly is damaged
and it needs repair or to be replaced. Refer to

7.2.8.10

.

If there is blockage or leakage in the power steering
system, clean the fluid pipes and the relevant parts.

If the oil pressure is too low, then the power steering leaks
or is damaged, replace the damaged power steering
pump assembly. Refer to

Warning!

Refer to "Battery Disconnect Warning" in "Warnings and
Notices" .

FE07-1021b

1.

Park the vehicle on a even surface and straighten the front
wheels.

2.

Disconnect the battery negative cable. Refer to

2.11.8.1

Battery Disconnection

.

Note

Disconnect the battery cable and wait for at least
60s, prevent airbag and seat belt pre-tensioner
being activated.

3.

Remove the driver front airbag. Refer to

9.2.7.2

Driver

Front Airbag Replacement

.

4.

Connect the battery negative cable.

5.

Use a torque wrench to check whether the steering wheel
nut fastening torque is correct.

6.

Start the engine and let the engine run at idle.

7.

Use a torque wrench to turn the steering wheel left and
right 90 degrees, check the left and right rotation torque.

Steering torque (reference): 5.5 Nm (Metric) 4.1 lb-ft (US
English)

Note

Before the test, consider the tire type, tire pressure
and the contacting surface.

8.

Disconnect the battery negative cable.

9.

Re-examine the steering wheel nut torque.

Torque: 45 Nm (Metric) 33.3 lb-ft (US English)
