SUZUKI scan tool.

8) Perform the following checks with help of another

person.
Brake pedal (1) should be depressed and then select
testing wheel by SUZUKI scan tool and the wheel (2)
should be turned by another person’s hand. At this
time, check that:
• Operation sound of solenoid is heard and the

wheel turns only about 0.5 sec. (Brake force is
depressurized).

• Operation sound of pump motor is heard and
