Programming the RV/Light Truck Display Module:
*CP – Cold Pressure
*Pd – Pressure Status Alert
*tr – Tire Rotation
*tA – Temperature Warning
*LP – Low Pressure Warning
*PA – Low Pressure Alert
*SL – Temperature Correlation
The tires on your vehicle may require a different cold pressure value
than the SmarTire System’s factor setting of 65 psi. You must change
the CP, LP, PA and SL settings accordingly to ensure optimum performance
for your specific tire application.
1. Turn on the ignition switch (the vehicle does not have to be running)
so the SmarTire Display Module lights up and you hear an initial beep.
2. To enter programming-mode, press either the ‘Mode’ keys or
tire ‘key’ to enter View Mode. Now hold the Mode and ‘Tire’
keys down simultaneously until ‘CP’ (Cold Pressure) appears
on the screen.
3. Press the ‘Tire’ key. You will now see only the two
front tire indicators.
4. Press ‘Mode’ key to show the cold pressure factory settings.
If this is not the correct pressure reading for your tires, press the
‘Tire’ key to increase or the ‘mode’ key to decrease
to the correct settings.
5. To save your changes, press both the ‘Mode’ and ‘Tire’
keys down simultaneously until CP appears on the screen.
6. To set the ‘CP’ value in the other tire locations, repeat
steps 3 through to 5, except in step 3 press the ‘tire’ key to
select the desired rear tire indicators.
7. Press your ‘Mode’ key once. tr (tire rotation) will
now show on your screen.
8. Press ‘Tire’ key four or six times. You will see –an
ID number representing the sensor in each tire location. If tire locations
are changed it will be necessary to update the ID numbers in the display
module by pressing the Mode’ key. Individual ID numbers can only
appear once and if ‘ER’ is displayed upon exit check and
correct ID error.
9. To save your changes, press the Mode’ and ‘Tire’
keys; simultaneously until you see ‘tr’ on the display.
10. Press the ‘Mode’ key until you see PA (pressure alert)
on the display.
11. Press the ‘Tire’ key to display the factory setting.
If it is not correct, press ‘Mode’ key to decrease or, ‘Tire’
key to Increase to the desired setting.
12. To save your changes, press the ‘Mode’ and ‘tire’ keys
simultaneously until you see PA’ on your screen.
13. Press your ‘Mode’ key until you see ‘LP’ (low
pressure warning).
14. Press the ‘Tire’ key to display the factory setting.
Press ‘Mode’ key to decrease or, ‘Tire’ key
to increase.
15. To save your changes, press the ‘Mode’ and ‘Tire’
keys simultaneously until you see ‘LP’ on your screen.
16. Press the ‘mode-‘key until you see ‘Pd’ (pressure
status alert).
17. Press the ‘Tire’ key to set the factory ‘Pd’ setting.
18. Press ‘Mode’ key to decrease or, the ‘Tire’
key to increase the setting.
19. To save your changes, press the ‘Mode’ and ‘Tire’
keys simultaneously until you see ‘Pd’ on your screen.
20. Press the ‘Mode’ key until you see TA (Temperature
Warning).
21. Press the ‘Mode’ key to decrease or the ‘Tire’
key to increase.
22. To save your changes, press the ‘Mode’ and ‘Tire’
Keys simultaneously until to see TA on your screen.
23. Press the ‘Mode’ key until you see ‘SL’
(temperature correlation),
24. Press the ‘Mode’ key to decrease or the ‘Tire’
key to increase.
25. To save your changes, press the ‘Mode’ and ‘Tire’
key simultaneously until you see ‘SL’ on your screen.
26. To exit the program mode, press the ‘Mode’ and ‘Tire’
keys simultaneously until the Display is returned to stand-by.
Troubleshooting / Installation Hints
Confirm sensor operation: before mounting the Sensors, plug in the Display
Module and then shake the Sensor near the Module. This should activate
the Low-pressure Warning mode and display a 0-pressure reading. This
test confirms that the Sensor Is Working.
No receptions from a sensor on a vehicle: This may mean there is a
reception problem. Position the Display Module Either on the dash or
visor and extend the antenna that is located in a groove on the back
of the Module.
Activation of viewing functions: After driving for approximately 15
seconds –above 5Mph, the tire indicators will begin to appear
on the display. To obtain tire initial pressure readings from all of
the sensors, you must drive for approximately 30 Seconds and for initial
temperature readings, you must drive for approximately 1 minute. If
you are stopping and starting, it make take longer to receive the temperature
values as the transmission sequence is reset with every stop.
Based off of the information you have given us we have set your factory
settings as followed. You may need to still adjust these settings after
you have had your motor home weighed and know what your air pressure
should be.
Cp.=cold pressure front __________
Cp.=cold pressure rear __________
Pa.=pressure alert front __________
Pa.=pressure alert rear ____________
Lp.=low pressure front ___________
Lp.=low pressure rear _____________
Pd.=status for all tires (one setting) __________
Ta.=high Temp. warning for all tires (one setting) ___________
Sl.=slope front __________
Sl.=slope rear ___________
Tr.=tire rotation. No settings needed at this time of installation
Un.=standard/metric. No settings needed at this time.
**Make note that each sensor is marked for a specific tire location.**
