HYDRAULIC UNIT CHECK

M1354003400029

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 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.
