DIAGNOSIS SYSTEM (SIREN CONTROL UNIT)

Diagnosis Description

INFOID:0000000010479870

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 sensors.

- 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 SYSTEM (SIREN CONTROL UNIT)

Self-diagnosis is performed as shown in the figure.

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.

• 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.

>> GO TO 2.

2.

CHECK CIRCUIT DIAGNOSIS RESULT

Check circuit diagnosis result display.
The diagnosis result is displayed by hazard warning lamp blink as per the following.

Does hazard warning lamp blink?

YES

>> GO TO 8.

NO

>> GO TO 3.

3.

CHECK VEHICLE SECURITY SYSTEM OPERATION 1

1.

Turn ignition switch OFF.

2.

Close hood and all doors.

3.

Lock all doors using the Keyfob or door request switch.

4.

Check that security indicator lamp blink quickly for 20 seconds. (PRE-ARMED phase)

Does security indicator lamp blink quickly?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

CHECK MALFUNCTIONING CIRCUIT 1

Check power supply and ground circuit for siren control unit. Refer to 

SEC-271, "SIREN CONTROL UNIT :

Diagnosis Procedure"

.

>> INSPECTION END

5.

CHECK VEHICLE SECURITY SYSTEM OPERATION 2

1.

Check that security indicator lamp blinks slowly. (ARMED phase)

2.

Check if siren sounds 5 time or not. Refer to 

SEC-195, "VEHICLE SECURITY SYSTEM : System Descrip-

tion"

.

Does siren sound?
