INTRODUCTION
The SmarTire
®
by Bendix CVS Tire Pressure Monitoring
System (TPMS) consists of a tire pressure sensor inside
each tire that transmits Radio Frequency (RF) signals
containing a unique Identification Number (ID #), actual
tire pressure, temperature, and sensor battery condition
to an Electronic Control Unit (ECU) attached to the
vehicle’s J1939 communication bus. This ECU receives
and interprets the RF signal(s) from the sensor and warns
the driver of an abnormal tire condition.
It is important that the ECU is programmed correctly with
each sensor location on the vehicle so it can indicate to
the driver which tire has the incorrect pressure and/or
excessive temperature. Each time the tires are serviced
or rotated, the ECU must relearn the current position of
each tire pressure sensor and tire and wheel assembly.
The BT36 Low-Frequency (LF) maintenance hand tool
is used to facilitate this learning process. It can also be
used as an electronic pressure gauge to measure the
current pressure and temperature of any tire on a vehicle
equipped with Bendix TPMS sensors.
