IVMS COMMUNICATION INSPECTION
IVMS contains the IVMS communication diagnosis and wake-up diagnosis.
IVMS Communication Diagnosis
●
IVMS communication diagnosis consists of the communication diagnosis, sleep diagnosis, and inactive
communication diagnosis between BCM and each local unit (LCU), and display the results on the CON-
SULT-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)
*: malfunctioning item record
Operation Procedure
1.
Touch “IVMS-COMM CHECK” on “SELECT TEST ITEM”.
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.
Perform the communication inspection again to make sure 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.
NOTE:
If any unspecified switch is operated, “Switch data not match” is displayed as a malfunctioning system.
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.

completed and the transmitted data and received data are identically the same. In
other cases, it is judged malfunctioning. If the communication is inactive, no diagno-
sis result is displayed.
Inactive communication
NO RESPONSE
Communicating with each LCU is judged sound when at least one time communica-
tion is normally completed within three trials. In other cases, it is judged malfunction-
ing.
Sleep malfunction

NOTE:
●
For a specific local control unit (LCU), either “PAST COMM DATA” or “PAST NO RESPONSE” may be displayed instead of the
above results. This is caused by the data record, 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
reproducible incident occurred.)
●
Follow the steps below to erase the memory
Perform 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, the BCM
stores “NO RESPONSE” record.
