Components
6.1.2 The internal sensor (WIS)
NOTICE
Risk due to incorrect handling
Changes or manipulations of any kind to the sensor, in particular an attempt to change the battery,
will destroy the device and can lead to tire damage.
– Adhere to the maximum torques and use screws with locking paint.
– Do not use balancing powder.
NOTICE
Functional limitations due to incorrect installation
Vehicles that are equipped with external sensors (WM2) may not function when the ECU receiver is
in the same position when the external sensors are replaced with internal sensors (WIS).
– Install the receiving ECU maximum 3m away from all wheel hubs.
– Install the spare wheel so that the sensor points in the direction of the receiving ECU.
– Run a system test when you have replaced the external sensors with internal sensors.
Information and technical data
INTERNAL SENSOR (WIS)
WABCO part numbers 960 732 000 0
Pressure range 0 to 13 bar correspond to the nominal values of pressures from 3 to 10 bar
Transmission intervals Every minute
Counterweight Not required
Installation
Installation on the rim by means of valve neck.
Fastened to a special tire ination valve with a 6 mm hollow screw coated
with locking varnish.
The tire valve must match the installation conditions of the original valve.
In the interior the mounting surface for the valve must be aligned so that
the internal sensor rests at and level on mounting surface. This prevents
large forces acting on the internal sensor and tearing it off during tire
assembly/disassembly.
Start-up
Using the WABCO OptiTire TPMS Manager (WABCO part number
300 200 001 0)
Purpose and function
In addition to monitoring the tire pressure, the internal sensor also enables an indication of the tire
temperature.
