OptiTire can be interrupted in its function if other devices or systems in the vicinity are also
transmitting in the area of 433 MHz. These can be radio sets, radio remote controls (e.g. for
door actuation, cranes, forklift), insufciently shielded electrical drives with high power or other
radio transmitters. When the OptiTire system is removed from the area of interference, the
function is guaranteed again.
6.1 Sensors
General information and technical data
SENSORS (APPLIES TO INTERNAL AND EXTERNAL SENSORS)
Material Plastic (moulded and self-contained)
Integrated components
Pressure sensor
Circuit for evaluation
Radio transmitter and battery
Radio transmission 433 MHz signal
Transmission intervals
Depends on the sensor type
The transmission frequency is increased when there are pressure changes
Repairs Not possible
Warning messages With position on the vehicle
Battery
Lithium
Service life: up to 9 years
Around 6 months before the end of its service life the sensor transmits a
warning signal that the battery is exhausted
Sensor ID
An ID makes each sensor unique and ensures that the sensors are clearly assigned to particular
wheels. The sensor will "report" to ECU using this code. This will exclude pressure signals from other
vehicles to be assigned to own system. The ID is dened when the sensor is manufactured and cannot
be changed.
This ID is imprinted on the sensor for start-up.
The ID can also be read out wirelessly using the WABCO OptiTire TPMS Manager (WABCO part
number 300 200 001 0).
