IVMS COMMUNICATION INSPECTION

●

IVMS contains the IVMS communication diagnosis and wake–up diagnosis.

IVMS Communication Diagnosis

●

The IVMS communication diagnosis consists of the communication diagnosis, sleep diagnosis, and inac-
tive communication diagnosis between BCM and each local unit (LCU), and display the results on the
CONSULT–II screen. 
NOTE:
Sleep is a power saving function when a vehicle is stationary (all BCM related electrical equipment: OFF,
and the timer: OFF).

●

The function also stores the communication malfunction records and inactive communication records, and
displays the data on the CONSULT–II screen (Malfunction record diagnosis)

Communication malfunction

COMM DATA

●

Communicating with each LCU is judged sound when the communication is 
normally completed and the transmitted data and received data are identi-
cally the same. In other cases, it is judged malfunctioning. If the communica-
tion is inactive, no diagnosis result is displayed.

Inactive communication

NO RESPONSE

●

Communicating with each LCU is judged sound when at least one time com-
munication is normally completed within three trials. In other cases, it is 
judged malfunctioning.

●

Check that each LCU enters sleep mode.

Operation Procedure

1.

Touch "IVMS–COMM CHECK" on "SELECT TEST ITEM" screen.

2.

Touch "IVMS–COMM DIAGNOSIS" on "SELECT DIAG ITEM" screen.

3.

Touch "START" on "IVMS–COMM DIAGNOSIS" screen to start the diagnosis.

4.

After the diagnosis is completed, the malfunctioning system is displayed.

5.

When the malfunctioning items are displayed, touch "PRINT" to record.

6.

Touch "ERASE".

7.

Carry out the communication inspection again to check that any malfunctioning item is displayed.

8.

Check the displayed items. 

Wake-Up Diagnosis

●

The wake-up diagnosis is carried out when BCM detects the wake-up signal from each local unit (LCU).
When the switch shown on the screen is operated as instructed, each local control unit(LCU) outputs the
wake-up signal. If BCM cannot detect a wake-up signal, it is judged malfunctioning. The malfunctioning
local control unit(LCU) is displayed on the screen.

Operation Procedure

1.

Touch "IVMS–COMM CHECK" on "SELECT TEST ITEM" screen.

2.

Touch "WAKE–UP DIAGNOSIS" on "SELECT DIAG ITEM" screen.

3.

Touch "START" on "WAKE–UP DIAGNOSIS" screen to start the diagnosis.

4.

Touch "NEXT" to select the local control unit (LCU) to be diagnosed.

5.

Check that any malfunction is displayed. If necessary, touch "PRINT" to record.

6.

Carry out the inspection to the malfunctioning item.

NOTE:

●

For a specific local control unit (LCU), either "PAST COMM DATA" or "PAST NO RESPONSE" may be displayed instead of the
above results.The data record,  causes this, so erase the records.
(The display only shows the incident records, they are not malfunctions caused during the diagnosis. One possible cause is that an
intermittent incident occurred.)

●

Follow the steps below to erase the memory. 
Carry out either disconnect BCM battery power supply or erase memory with CONSULT-II.

●

With the battery connected, if the local control unit (LCU) connector is disconnected and left for approximately 1 minute, BCM
stores "NO RESPONSE" record.
