and the timer: OFF).

*: Malfunction item record

Operation Procedure

1.

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

2.

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

3.

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

4.

6.

Touch “ERASE”.

7.

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

8.

Wake-up Diagnosis.

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

Operation Procedure

1.

Touch “IVMS-COMM CHECK” on the “SELECT TEST ITEM” screen.

2.

Touch “WAKE-UP DIAGNOSIS” on the “SELECT DIAG ITEM” screen.

Diagnosis content

Communication malfunction

COMM DATA

Communicating with each LCU is judged normal when communication is normally
completed and when both transmitted data and received data are equal. 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 normal when at least 1 communication is
normally completed within 3 trials. In other cases, it is judged malfunctioning.

Sleep malfunction

SLEEP

Check that each LCU switches to sleep mode.

Communication malfunction*

PAST COMM
DATA

The records when communication signal, malfunctions were continuously detected
while the communication was normal are displayed, or a malfunction was detected

Trouble Diagnosis Chart

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, the BCM
stores “NO RESPONSE” record.
