NOTE:
1: 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.
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 started when ABS warning lamp and brake warning lamp are ON.
ABS warning lamp and brake warning lamp are ON during active test.
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.
