• Never perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be started when ABS warning lamp, VDC OFF indicator lamp, SLIP indicator
lamp and brake warning lamp are ON.
• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are ON
during active test.
• Erase memory of the lane camera unit after implementing active test. Refer to
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” in “ABS” with CONSULT-III is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” in “ABS” with CONSULT-III is displayed, to perform test again.
