  • Theft deterrent system is in the alarm sounding state of the active mode.
  • No key is in the ignition key cylinder.
  • Any of the front doors is unlocked.

  • All doors are locked.
  • The alarm has finished.
  • The key is inserted into the key cylinder.

6. Operate glass breakage sensor

  1. If the glass breakage sensor detects the glass is broken (at 1st time), the sensor will issue an alarm for 20 seconds (pre–alarming). If the glass breakage sensor detects the glass is broken further more (at 2nd time), the sensor will issue an alarm for 60 seconds.
  2.  the sensitivity of the glass breakage sensor can be adjusted by the volume switch in the glass breakage sensor ecu.

Hint

: because the glass breakage sensor has a high sensitivity, it might issue a wrong alarm if it is adjusted in the volume of high sensitive.
