1.
CHECK ACTIVE TEST
1.
On “ACTIVE TEST”, select “ABS MOTOR”.
2.
Touch “On” and “Off” on screen. Make sure motor relay and actuator relay operates as shown in table
below.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is
an operation for checking.
Is the inspection result normal?
YES
>> INSPECTION END
