FAQ

What do I do if my sensor is not reading?

• Unscrew the sensor off the valve stem and then reinstall it. The sensors are pressure sensitive and will reset once reinstalled.
• If it still does not read, try placing a working sensor from another tire on that valve stem. Keep in mind, the sensor you just moved will continue to read in its original tire position on the display. If that sensor does not read normally, you may have a valve stem problem. Try unscrewing the valve core as described above. If the switched sensor reads normally, it may be a sensor issue.
• If your sensor is not transmitting data to the display, check to see if your sensor code has been input into the display correctly. A “d” and a “6” can look similar.

Why does my display sometimes “drop” sensor data from a tire position?

• If you have a unit that exceed 34’ in length, you may need a repeater to amplify the sensor signals from the tires to the display. This issue is not limited to the rear tires on a vehicle. A unit with a lot of metal, like an Airstream trailer, also needs a repeater.
• Be aware that an indoor/outdoor thermometer with an external temperature sensor may interfere with the TST TPMS. Temporarily remove all the batteries in the thermometer AND exterior sensor and see if the problem is corrected. A thermometer with a higher frequency (915 MHz) may be required. Atomic clocks can also cause interference with the sensors.

Why does my display sometimes alarm while I am sitting still in the evening?

As night approaches and outdoor temperatures decrease, your tire pressures may drop below the parameters you have set, thus causing an out of spec alarm. When temperatures drop, turn your monitor off overnight. As the air temperature rises the next day or as you start driving, the tires will also heat up and come back into your parameters. You can also add air to your tires to bring them back into the parameters you set up.

Why can’t I set a lower pressure than 100 lbs. for the high or low-pressure alarm?

The high-pressure alarm cannot go lower than the lowpressure alarm default setting. If your tire pressure settings are below 100 lbs., you must first set the lowpressure alarm and then come back to the high-pressure settings using the “MODE” button and set the axles highpressure alarm. When done, be sure to press and release the “SET” button to save all the parameter settings. See “Parameter Settings” above.

What conditions cause the display to alarm?

• A rapid leak (icon at bottom of screen).
• A low sensor battery (lower left battery icon blinks).
• An overheated tire temperature (temperature icon bottom of screen).
• A High or Low pressure reading (be sure your parameters are set correctly).

In every instance, the tire Pressure and Temperature numbers will also flash when the tire having the problem flashes. The lower red alarm light will also flash.

How do I remove my trailer from the display screen when I am not using it?

To electronically disconnect the trailer tire icons from the screen:

• Press and hold the “MODE” and (-) buttons.
• When the trailer section on the display disappears, release the buttons.
• To electronically reconnect the trailer section, again, press and hold the same “MODE” and (-) buttons.
• When the trailer section on the display reappears, release the buttons

How do I remove an unwanted tire icon from the display?

• Hold down the “SET” button until it beeps and then release it.
• Navigate to the tire you want to remove from the screen by quickly pressing the “SET“ button to move through the tire icons.
• When at the correct tire, use the (+) or (-) buttons to adjust the first digit to an “F”.
• Quickly push and release the “MODE” button to move to the next digit. Set that to “F”.
• Continue until all digits are set to “F”.
• When “FFFF” is showing, press and hold the “SET” button until it beeps to save the code.
• You will be back to the Main Screen and the tire icon will be gone.
