Counter weight
To prevent the whee causi imbalan on the wheel, a counterweight
ounted on the op 4-2 " ith c terweight",
19.
Axles with twin tires do no
t need counterweight. In this case, the wheel module of
one wheel serves as counterweight for the wheel module of the other wheel. They
are mounted opposite to one another, see figure 4-3 "Module for twin wheels",
page 19.

ID code
Special identification code of each wheel module allows unique assignment of
modules to particular wheels. The wheel module will "report" to ECU using this
code. This will exclude pressure signals from other vehicles to be assigned to own
system. Code is dete m s man d and cannot be changed.
This number is imprinted on the wheel module when commissioning.
in wh
rmined when od
ule i ufacture
Assignment between wheel and wheel module must be absolutely maintained tire-
change procedure. If tires were confused, IVTM could not set off required alarm
when a wheel with low pressure has been wrongly assigned to an axle on which
ssure is still pthis pre ermissible.
Identification code assig determined during initial start-up of the
diagnostic software on commissioning, see chapter 6.6 "Start-up", page 37.
