SmarTire®by Bendix CVS Tire Pressure Monitoring System (TPMS)
BT36 Low-Frequency (LF) Maintenance Hand Tool
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 Identication 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.

OPERATION
Turning on the BT36 LF Maintenance Hand Tool
See Figure 1. Press the button to turn on the tool.
The initial splash screen will display the current software
version. Please make a note of this software version
before calling technical support.

The BT36 Low-Frequency (LF) maintenance hand tool is
capable of sending two di󰀨erent activation signals.
• LF Initiate – Used to retrieve current pressure,
temperature and battery status from a sensor.
• LF Learn – Used to learn the sensor ID # into the
Tire Pressure Monitoring System (TPMS) Electronic
Control Unit (ECU).
Initiate Mode
1. To select the LF initiate function, use the up/down
arrow keys and then press OK.
Figure 3 – Initiate Mode Menu
2. See Figure 3 for the menu that is displayed.
3. See Figure 4. Hold the BT36 LF maintenance hand
tool approximately 2 in. (5 cm) away from the tire’s
surface (positioned at the center of the tire’s sidewall
at the location of the valve stem). NOTE: Bendix
sensors should be installed at the valve and their
location should also be indicated by a rim-mounted
label.
Figure 4 – Sensor Installation Guidelines
4. See Figure 5. Press and release the button.
While the progress bar is displayed, continue to hold
the BT36 LF maintenance hand tool in position. This
can take up to 10 seconds to complete.

Status
NOTE: Gold Series sensors will not always return the
battery status. If you do not see the battery status, initiate
the sensor again. It may be necessary to initiate the sensor
several times before this information is returned.
6. Press and release the button to activate another
sensor, or press the button to return to the main
menu.

Learn Mode
1. To select the “LF learn function,” use the up/down
arrow keys and then press OK.
2. Follow the instructions above for the “LF initiate
function” to activate the Tire Pressure Monitoring
System (TPMS) sensor.
3. Depending on the sensor series, di󰀨erent screens will
be displayed. NOTE: For Black Series sensors, the
same information shown above will be displayed. For
Gold Series sensors, only the sensor ID # is displayed.
4. Press and release the button to activate another
sensor, or press the button to return to the main
menu.
Changing the Settings
From the main menu, use the up/down arrow keys to
select “options” and then press OK. See Figure 7 for the
settings menu displays.
• The “LF POWER” option is used to adjust the strength
of the activation signal. NOTE: It is recommended to
use the factory default setting. Adjusting the signal
too high or too low may impair the sensor reception.
• The “UNITS” option is used to select between Metric
and Imperial units.
• The “BUZZER” option allows you to enable or disable
the internal buzzer.
• The “CONTRAST” option allows you to adjust the
contrast of the LCD screen.
• The “AUTO OFF” option changes the length of time
before the tool turns o󰀨 when not in use.

Check the Battery Level
See Figure 8. Press and hold the button to display
the tool’s current battery charge level.

Charging the BT36 LF Maintenance Hand Tool
See Figure 9. When the BT36 Low-Frequency (LF)
maintenance hand tool’s battery level is low, use the
supplied wall charger and USB cable to charge the tool
by plugging it into the USB cable on the back of the BT36
LF maintenance hand tool.

Updating the BT36 LF Maintenance Hand Tool
The software in the BT36 LF maintenance hand tool may
occasionally be updated to add more features. To update
the BT36 LF maintenance hand tool to the latest software,
perform the following steps:
1. Install and run the WebVT software that came on the
CD with the BT36 hand tool.
2. Plug the BT36 LF maintenance hand tool into a USB
port of your computer using supplied the USB cable.
3. Turn the device on by pressing the button.
4. If a software update is available, a screen will appear
indicating “Update Device.” Follow the on-screen
instructions to update the software.

Programming Sensor ID Numbers in a TPMS ECU
Occasionally, it is required to update the ID # in a
SmarTire® by Bendix CVS Tire Pressure Monitoring
System (TPMS) Electronic Control Unit (ECU) due to
sensor replacement or tire rotation. The BT36 Low-
Frequency (LF) maintenance hand tool is used to facilitate
this re-learning of sensor ID #s along with the Bendix®
ACom®PRO™ diagnostic software. To update a sensor
ID #, perform the following steps:
1. Launch the ACom PRO software.
2. Use the “connect” button to connect to the vehicle
data bus.
3. Once all ECUs on the truck are found, click the
“bi-directional” button.
4. Select “Bendix TPMS ECU” from the left pane, and
then select “TPMS Conguration” from the right pane.
Press the “start” button.
5. Select a tire to change its sensor ID # by clicking its
tire icon.
6. Press the “Learn Using Hand Tool” button to place
the ECU into learn mode.
7. Use the LF Learn Mode procedure above to activate
the sensor for the corresponding tire location.
8. After successful activation, the new sensor ID #
should be displayed on the ACom PRO conguration
screen and the learn operation is now completed.
