Diagnosis Description

INFOID:0000000010923235

DIAGNOSIS FUNCTION

Siren control unit has a self-diagnosis function which displays the diagnosis results for the following items.
• Circuit diagnosis: Displays if malfunction exists or not in the circuits between siren control unit and BCM or

siren control unit and intruder sensor.

- Circuits are normal: Hazard warning lamp blinks 3 times.
- Circuit is malfunctioning: Hazard warning lamp does not blink.
• Alarm history: Displays alarm activation history for the maximum 3 items.
- Siren sounds for 0.4 seconds and sound interval is 0.4 seconds.
- When multiple symptoms exist, the interval between each alarm history is 2 seconds.

• Component diagnosis: Displays malfunctioning component (siren control unit or intruder sensor).
- Siren sounds for 1 second and sound interval is 0.4 seconds.
- When multiple symptoms exist, the interval between each diagnosis result is 2 seconds.

SELF-DIAGNOSIS PROCEDURE

1.

Connect CONSULT.

2.

Turn ignition switch ON.

3.

Select “ACTIVE TEST” mode of “THEFT ALM” of “BCM” using CONSULT.

4.

Select “SIREN” and touch “ON” to start self-diagnosis.

5.

Self-diagnosis result is displayed after 2 seconds.

DIAGNOSIS PROCEDURE

Precaution for Diagnosis Procedure

• Self-diagnosis result is erased from siren control unit when setting alarm system after performing the self-

diagnosis.

- When performing self-diagnosis, it is advised to record the self-diagnosis result display on a memo pad.
- When replacing siren control unit, never set alarm system after performing the self-diagnosis.

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

1.

INSPECTION START

Perform SELF-DIAGNOSIS PROCEDURE described above to start self-diagnosis.
