1.

CHECK ACTIVE TEST

1.

Select “ABS”, “ACTIVE TEST” and each test menu item in order with CONSULT-III.

2.

Select “Up”, “Keep”, and “Down”, and check that the system operates as shown in the table below.

*: On for 1 to 2 seconds after the select, and then Off.

NOTE:

A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is a
operation for checking.

Is the inspection result normal?

YES

>> INSPECTION END

NO
