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-ll 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)

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

Description

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 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 commu-
nication is normally completed within three trials. In other cases, it is judged 
malfunctioning.

Sleep malfunction

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.

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

NOTE:

For a specific local control unit (LCU), either "PAST COMM DATA" or "PAST NO RESPONSE" may be displayed instead of the

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 for approximately 1 minute, the BCM stores

DIAGNOSIS ITEM

COMMUNICATION DIAGNOSIS

Check the communication between BCM and local control unit (LCU).

How To Perform Communication Diagnosis

Description

In this mode, a malfunction code is indicated by the number of flashes from the map lamps and step lamps as
shown below:

After indicator lamp turns on for 2 seconds then off for 2 seconds, it flashes [cycling ON (0.5 sec.)/OFF (0.5
sec.)] to indicate a malfunction code of the first digit. Then, 1.5 second after indicator lamp turns off, it again
flashes [cycling ON (0.5 sec.)/OFF (0.5 sec.)] to indicate a malfunction code of the second digit.
For example, the indicator lamp goes on and off for 0.5 seconds twice and after 1.5 seconds, it goes on and off
for 0.5 seconds four times. This indicates malfunction code of driver door control unit communication.
