HYDRAULIC UNIT CHECK

M1354003400041

Required Special Tool:

•

MB991502: Scan Tool (MUT-II)

CAUTION

•

The roller of the braking force tester and the tire should
be dry during testing.

•

When testing the front brakes, apply the parking brake.
When testing the rear brakes, stop the front wheels
with chocks.

1. Jack up the vehicle. Then support the vehicle with rigid

racks at the specified jack-up points or place the front or rear
wheels on the rollers of the braking force tester.

2. Release the parking brake, and feel the drag force (drag

torque) on each road wheel.
When using the braking force tester, take a reading of the
brake drag force.
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.

3. Turn the ignition switch to the "LOCK" (OFF) position and

set scan tool MB991502 as shown in the illustration.

4. After checking that the selector lever <A/T> or the shift lever

<M/T> is in neutral, start the engine.

5. Use scan tool MB991502 to force-drive the actuator.

NOTE: The TCL system will switch to the scan tool mode
and the ABS warning light will illuminate.

NOTE: When the TCL has been interrupted by the fail-safe
function, scan tool MB991502 actuator testing cannot be
used.

6. Turn the wheel by hand and check the change in braking

force. Use a braking force tester. The braking force reading
value should change when the actuator test is carried out.
The result should be as shown in the diagram above.

7. If the result of inspection is abnormal, replace the hydraulic

unit (Refer to GROUP 35B, Hydraulic Unit

P.35B-51

.).

G EN ER A L DESC RIPTIO N

M1372000100070

The vehicle uses engine speed-responsive hydraulic
power steering.
The steering wheel has three spokes. In addition, all
vehicles are equipped with SRS (Supplemental
Restraint System).

The steering column in all vehicles has a shock
absorber mechanism and a tilt steering mechanism.
A vane-type oil pump with a fluid flow control system
has been included. The steering gear and linkage is
rack and pinion type.

PO W ER STEERIN G DIAG NO SIS

INTRODUCTION TO POWER STEERING DIAGNOSIS

M1372008500061

Hydraulic power steering is used for all vehicles.
Faults in the power steering can include excessive
play of the steering wheel, difficult steering wheel
operation, noise, vibration, and oil leaks, etc.
Possible causes of these faults can include defects
in the gear box, oil pump or steering linkage.
