    How To Check The Active Noise Cancellation System In This Check Mode 

    • While in this system check mode, press the No. 1 button to move to the next test item.
    • You must remember how many times you pressed the No. 1 button. The system will not show which test item you are doing.
    • For test items 1 thru 10, the speaker will make a low-frequency hum (50 Hz) when the system is normal for more than 5 seconds up to 1 minute.
    • When there is a failure in the system, the speaker will not make a low-frequency hum (50 Hz) or the hum will stop within 5 seconds for test items 1 thru 10.
    • The check mode will be automatically cancelled when the time reaches 1 minute after the starting each test items.
    • When you reach the 11th test item, the test loops in ON and OFF.
    • This check mode ends when you start the engine (ignition switch in START (III) or turn the ignition switch to LOCK (0), because the power to the audio system is cut off.
    • Since some tests require the engine to be running or stopped, you cannot do all these tests at once. If you need to check test item No. 2, No. 7, and/or No. 11, start the check mode with the engine idling. If you need to check test item No. 9 and/or No. 10, start the check mode with the engine stopped. Other test items are available with the engine running or stopped.
