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.

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.

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
SLEEP
Make sure that each LCU enters sleep mode.
