Tractor Interface Module Installation Guide 4
Testing TIM– SI Installation
It is recommended that each installation be tested
to ensure proper operation. To test the TIM-SI
reader performance after installing all the AirBAT
TPMS wheel-end sensors and the TIM-SI, follow
these steps:
1.
Verify Proper Installation
Visually ensure the following:
a. The GPS Antenna is connected to the TIM-
SI (SMA connector labeled “GPS”); the end
of the cable with the amplified antenna
(1¾” x 1¾” x ½” square box) is mounted
where is has a good view of the sky (to
receive the signal from the GPS satellites).
b. The TIM-SI is mounted at window height or
higher for good receive signal strength.
c. When powered on the Low Tire Alert light
may have a short flash of all colors followed
by green for about two seconds and then
goes out. If it flashes red after the green
this indicates that the GPS antenna is either
drawing too much current (replace it) or
drawing too little current (not connected;
connect or replace).
2.
Bind The AirBAT Sensors to the
TIM-SI
To bind the AirBATs to the TIM-SI, drive the
vehicle for at least 1 mile (straight line distance;
i.e. do NOT circle the block six times to equal 1
mile). For test purposes only, ensure the TIM-SI
is powered for at least 2 minutes prior to driving
to ensure the GPS has adequate time to acquire
the satellite signals (GPS must have view of the
sky with no roof overhead). After the test drive,
unplug the “+12 VDC Alert” connector found on
the left side of the TIM-SI. Wait for about 10
seconds until the Low Tire Alert light has stopped
blinking blue and has turned a solid red or the
light is off. Plug the cable back in and watch the
light blinks. The first blink may have a short flash
of all colors but then is green for about 2 seconds
confirming initial boot successful; then count the
number of blue blinks that follow which indicates
the number of sensors that are bound to the
TIM-SI. The number of blue blinks should match
the number of AirBATs that were mounted on the
vehicle during the drive to bind the AirBATs.
3.
Test the TPMS System
First verify that the OBC system provider
(Cadec, Qualcomm etc.) is properly configured
for that vehicle to send the alert all the way to
the back office (via logistics web page or email).
At the vehicle, loosen one of the AirBAT hoses
to drop the pressure and verify that the AirBAT
is blinking red. Verify that the TIM-SI Low Tire
Alert light begins blinking to indicate the low
pressure alert (should occur within 30 seconds
of AirBAT beginning to blink). Finally, verify that
the alert was received via the OBC system
provider (may take up to ten minutes depending
on the OBC provider).
If you are not successful with the installation and
need support, please contact your sales agent or

On-Board Computer Provider Compatibility
The TIM-SI was designed to provide a universal interface that will
work with most OBCs supplied to the market today. Contact STEMCO
customer support for the latest compatibility list if the OBC used by
your fleet does not appear in the list below.
