ACTIVE TEST
CAUTION:
• Do not perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be performed with the AB S warning lamp, VDC indicator lamp, SLIP indicator
lamp or brake warning lamp on.
• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on

NOTE:
• When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor)
• “TEST IS STOPPED” is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.
