SmarTire®TPMS Low Frequency (LF) Tool User Manual
1. INTRODUCTION
The SmarTire®Tire Pressure Monitoring System (TPMS)
by Bendix CVS consists of sensors (mounted using steel
bands onto the rim of the wheels), an antenna, receiver/
Electronic Control Unit (ECU), and dash display unit or
OEM integrated display.
A Sensor is Installed
Inside Each Tire
Antenna
Receiver/ECU
Dash
Display
Each tire sensor has a unique ID code and it is
important that the system knows the ID of the sensor
used at each tire location on the vehicle.
The SmarTire Low Frequency (LF) tool is a hand-held
device used to communicate with SmarTire-brand tire
pressure monitoring system sensors.
This document will describe how the tool can be used
to program one or more new sensor ID codes into the
receiver (for example, when replacing a sensor or after
repairs/tire rotation, etc.); and how to check that all IDs
are in the expected locations when conducting a vehicle
inspection. (See BW2799 for information about other
procedures, such as loading a system conguration.)

7. TROUBLESHOOTING
The following messages may be displayed at the end of
the Learn process if it was not completed successfully:
A. Learn Time Out. The receiver did not receive an
expectedresponsefrom a sensor within three(3)minutes
after being requested to learn a tire, and so the system
“timed- out”. Re-attempt to communicate at least twice.
If unsuccessful, a sensor may be pointing directly down
into the ground, or away from the Gateway or Antenna,
causing the signal reception to be disrupted. In these
cases, it may be useful to move the vehicle forward or
backward about a half-turn of the wheels, to reposition
the sensor, and then retry.
It can be useful to look to see if the tire stems for dual-
wheel assemblies are installed with their valve stems
arranged 180° from each other, as recommended. If still
unsuccessful,tryto initiate the sensoratthebottom of the
wheel, no matter where the valve stem is located. If this
attempt was successful, rotate the wheel 180 degrees
forward and initiate the sensor again at the BOTTOM of
the wheel. If the second initiation also provided a result,
itis evidence ofa broken cradle and/orstrap. The sensor
is simply falling to the lowest point in the wheel after each
rotation. Removethetireandreplacethecradleandstrap.
Dependingonthedamagedonetothesensor itself, it may
simply be pressed into a new cradle for reuse, however,
do not reuse the strap.
It is also important to check that the tool is held about
two(2) inches from the tire during the procedure – and
not touching the rim.
B. Duplicate Sensor ID. Thesensor ID that was received
for the wheel position is already programmed into the
system at another wheel position. (This may occur when
rotatingwheelsifthe original set of locations hasnot been
erased.) Repeat the process, ensuring you are initiating
the sensor you wish to learn. Take care when working
with dual tire assemblies to communicate with the correct
tire position.
It can be useful to look to see if the tire stems for dual-
wheel assemblies are installed with their valve stems
arranged 180° from each other, as recommended. You
can verify the location of the sensor in most cases, by
lookingforthe label attached to therimduringinstallation.
If still unsuccessful, try to initiate the sensor at the bottom
ofthewheel,no matter where the valve stemis located. If
thisattemptwassuccessful,rotatethewheel180degrees
forward and initiate the sensor again at the BOTTOM of
the wheel. If the second initiation also provided a result,
itis evidence ofa broken cradle and/orstrap. The sensor
is simply falling to the lowest point in the wheel after each
rotation. Removethetireandreplacethecradleandstrap.
