   * Definition of terms

   1. Bulb check 6s driver indicator blinking : In case of IGN1 0 → 1, the indicator will be outputted.
   2. Bulb check 6s buzzer: In case of IGN1 0 → 1 when it is unbelted, the buzzer will be outputted. will be outputted.
   3. Normal 6s driver indicator blinking: In case of Belted → Unbelted at the status of IGN 1, the indicator will be outputted.
   4. Normal 6s buzzer: In case of Belted → Unbelted at the status of IGN 1, the buzzer will be outputted.
   5. ALT L 6s indicator blinking: In case of ALT L 0 → 1, the indicator will be outputted.
   6. ALT L 6s buzzer: In case of ALT L 0 → 1 when it is Unbelted, the buzzer will be outputted. Unbelted

   **6s driver Indicator blinking : it flickers for 6 sec with the cycle of 1 sec.

3. KEY OPERATED WARNING
   1. When Driver Door SW is ON at the status of KEY IN ON, Buzzer will be outputted per 0.6 sec continuously.
   2. If KEY IN turns OFF or Driver Door SW is CLOSED during Buzzer output, the output will turn OFF.
   3. When IGN1 turns ON while outputting, the output will be stopped.
