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.
