IVMS Communication Diagnosis

The 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 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 dis-
plays the data on the CONSULT–II screen (Malfunction record diagnosis)

*: malfunctioning item record

Operation Procedure

Touch “IVMS–COMM CHECK” on “SELECT TEST ITEM”.

Touch “IVMS–COMM DIAGNOSIS” on “SELECT DIAG ITEM” screen.

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

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

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

Touch “ERASE”.

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

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.

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.
