Workshop notes
10.1
Maintenance
OptiTire
TM
does not require maintenance.
Only when the display indicates a malfunction, fault finding must be performed
with diagnosis
10.2
Replacement and repair
10.2.1
Replacing an IVTM ECU with an OptiTire
TM
ECU
In principle, the OptiTire
TM
is backwards compatible to the IVTM ECU, but the
following differences need to be noted:
Assembly: If the original IVTM retaining plate and associated 8 mm screws
are used, either cap nuts or suitable washers must be used in addition to
compensate the 11 mm holes in the OptiTire
TM
housing.
The adapter connector (WABCO part number 894 600 001 2) should be
used to connect the original IVTM cable.
A new Diagnostic Software is required because OptiTire
TM
is addressed by
means of a UDS diagnostic protocol (IVTM: KWP2000).
10.2.2
Replacing 1st generation external sensor with a 2nd generation
sensor
To select the correct 2nd generation external sensors, the rim shape (ET, size)
is also important alongside the 1st generation external sensors that are to be
replaced. The appropriate 2nd generation external sensor and matching PA
tube can then be selected on this basis.
10.2.3
Wheel change
Wheel with external sensor
Due to the external fixation of the sensor on the wheel bolts after wheel change
a new sensor is not needed. It is only to be ensured, that after wheel exchange
the sensor is fitted exactly to the same position as before.
As long as the external sensor itself is not exchanged, there is no need for new
settings of system parameters.
!
The external sensors are not allowed to be swapped with each other.
Make sure that the external sensor are respectively located in the original
position on the vehicle after the wheel change.
Especially with dual tires, the accurate relationship to the inner or outer wheel
must be observed.
Please perform wheel changes as follows:
–
Remove any dirt from the external sensor and PA tube.
