IVMS-
COMM CHECK
IVMS-
COMM DIAGNOSIS
Diagnosis of continuity in the communication line(s), and of the function of the
IVMS-communication interface between the body control module and the
local control units, accomplished by transmitting a signal from the body con-
trol module to the local control units.
WAKE-UP DIAGNOSIS
Diagnosis of the“ wake-up” function of local control units by having a techni-
cian input the switch data into the local control unit that is in the temporary
“sleep” condition.

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.
5.
Check that any malfunction is displayed. If necessary, touch “PRINT” to record.
6.
Preform the inspection to the malfunctioning item.

Description
Communication malfunction
COMM DATA
Communicating with each LCU is judged sound when the communication is nor-
mally 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 diagnosis result is displayed.
Inactive communication
NO RESPONSE
Communicating with each LCU is judged sound when at least one time communi-
cation is normally completed within three trials. In other cases, it is judged mal-
functioning.
Sleep malfunction
SLEEP
Make sure that each LCU enters sleep mode.
Communication malfunction*
PAST COMM
DATA
The records when communication signal malfunctions were continuously
detected while the communication was normal are displayed. Or the records
when a malfunction is detected during the past sleep mode are displayed.
Inactive communication*
PAST NO
