Introduction
Testing Tire Sensors
The sensor test procedure is used to verify the sensors can transmit
valid data after they have been activated with a Low Frequency (LF)
transmission from the tool.
The tire pressure monitoring system consists of a tire pressure sensor
inside the wheel that will transmit a radio frequency (RF) signal that
contains a unique identification number (ID #), actual tire pressure, and
sensor battery condition to a module in the vehicle. The vehicle module
receives and interprets the RF signal from the sensor and warns the
driver of low tire pressure.
This test cannot verify if the sensor’s internal roll switch is functioning
properly, for that, a test drive is necessary. Refer to the vehicle service
manual for further diagnostic information. During this procedure the tool
receives sensor transmissions and displays the transmission data on the
screen.
It is important that the vehicle module knows where each sensor is
located on the vehicle, so it can indicate to the driver which tire is low on
pressure. This means that when the tires are serviced or rotated, the
vehicle module must relearn the position of each tire pressure sensor
and tire and wheel assembly.
1. The antenna of the tool should be placed against the sidewall above
the wheel rim at the valve stem location. Holding it to close to the rim
(while initiating an inner tire sensor on a dual tire configuration, may
cause the outer tire to be initiated as well).
2. Press and release the Initiate button on the tool. The circling symbol
indicates the tool is scanning for the sensor's transmission.
The tire pressure sensor outputs for a definitive period of time once the
Activate button is pressed. 3. With the tool, observe the screen and wait 3-5 seconds for the
sensor's transmission to be received. The screen should display an 8-
digit ID number, tire pressure within 2 psi of actual tire pressure,
Learn mode and good signal strength.
The main menu of the tool identifies 3 functions consisting of Initiate,
Setup and Learn modes respectively. 4. Repeat step 3 for the remaining sensors to verify all sensors are
operating properly.
NOTE: Sensor transmission data displayed on the tool screen is
erased each time the Initiate or Learn functions are selected.
Tire Rotation
It is important that the receiver has learned the correct locations of each
tire pressure sensor so the system indicates the correct location of the
tire pressure condition, as well as sensor location for diagnostic
procedures. Perform the sensor learn procedure after every tire rotation,
sensor replacement, or receiver replacement.
1. Enable the tire pressure sensor learn mode in the receiver.
Refer to the vehicle service manual for more information.

Measurement Units 3. Select the walk around icon .
PSI/BAR/kPa/C/F 4. Select the number of tires on the vehicle example. A typical
heavy-duty truck contains 10.
This function changes the measurement units of the parameters
displayed. 5. Activate each of the vehicle's wheel sensors in the proper order (see
service information for the activation order).
6. Hold the SmartWave tool’s antenna against the tire’s upper sidewall
in line with the valve stem. Press the Learn button . The tool is
able to receive signals from an inner tire on a dual tire configuration
as well. Just hold the tool in line with the circumferential position of
the valve stem of the inner wheel.
Stored Sensor Information Retrieval
This function allows the user to refer to sensor information stored in the
tool memory. Up to 100 sensors readings can be stored & retrieved.

Walk-Around Learn
Walk-Around Learn Procedure
When the tires are rotated or replaced on a vehicle with a tire pressure
monitoring system, the vehicle must re-learn the position of each tire.
The Walk-Around Learn procedure is used to activate each sensor in its
new location, store the sensor information and download to the vehicle’s
Tire Pressure Sensor Receiver.
The unit will learns and stores the location of each sensor as the user
walks around the vehicle in a U-shaped pattern starting at the left side
(looking forward) front most tire location. If this is a dual tire axle start
with the inner tire location. The new location information (tire IDs) for
each sensor collected is then uploaded to the receiver in the vehicle.
Perform the following steps:
1. Power up the vehicle’s Tire Pressure Sensor Receiver (see vehicle's
service information for specific details).
2. Press and hold the Setup button until a list of menu items appear.

7. Once the tool has learned the tire sensor ID for the given position,
automatically switches to the next tire position. Repeat until all the
tires have been learned.
8. After the last tire has been learned, press the down arrow, you are
now ready to transmit this information to the vehicle’s Tire Pressure
Sensor Receiver.
9. Using the supplied cable, connect the tool to the diagnostic port of
the Tire Pressure Sensor Receiver.
10. Press the check mark to begin downloading the new tire sensor IDs
into the receiver.
11. If there is a communication error, the tool displays a warning. Check
all the connections and try again
12. If the tool screen reverts back to the screen for entering the number
of tires, then the number of tires that was entered does not match the
number of tires in the vehicle’s receiver. Make sure the number of
tires entered on the tool matches the number of tires being
monitored to the vehicle and repeat the Walk-Around Learn
procedure.

Troubleshooting
The tool does not power up or
turns off when the Activate
button is pressed.
Replace batteries.
No tire pressure sensor data
is received. Make sure the Activate Antenna is held within 22” of the tire pressure sensor in
position before the Activate button is
momentarily selected and that tool is held
in that position for at least 3.5 to 5
seconds. Try to activate and receive tire
pressure sensor data from another tire
pressure sensor.
Setup menu button does not
work. Be sure to press and hold the button for 2 seconds.
The tool does not receive a
sensor transmission after a
sensor has been activated.
Make sure the tool's antenna is held
within 6 inches of the sensor when
activating a sensor.
This process may need to be repeated up
to 3 times. If a sensor continues to not
respond, refer to the vehicle service
manual for further diagnostic or repair
information.
Wrong sensor initiated
(dual tire only). When initiating a sensor in a dual tire configuration the ID codes received
are the same for both the inner and
outer tires, the antenna of the tool
should be moved within 6 inches of
the tire pressure sensor (the antenna
should be held against the outer tire
when activating the inner tire on a
dual tire configuration)
