DIAGNOSIS SYSTEM (SIREN CONTROL UNIT)

• The display pattern of the self-diagnosis is complicated. Therefore, repeat self-diagnosis multiple times to

check the display pattern correctly.

- Malfunctioning part and alarm activation history can be checked effectively by comparing self-diagnosis

result display and the record on the memo pad.

• It is advised to obtain and record information for the following items which are necessary when investigation

is needed.

- Self-diagnosis result (Circuit diagnosis, Alarm history, Component diagnosis)
- Conditions of alarm activation (Place, Time, Weather)
- Articles in passenger room (Accessories, Cellular phones, Beverage containers, and others)
- Opening and closing status of door windows 
- Record and timing of battery discharge and battery replacement
- Serial number of siren control unit (on siren control unit label)
- Serial number of intruder sensor, if this sensor is cause of malfunction or alarm activation
