WHAT DO I DO IF MY SENSOR IS NOT READING?
1. If your sensor is not transmitting data to the display, try recoding the sensor to the same tire position using the “PROGRAM
SENSORS TO DISPLAY” instructions on the previous page.
2. If after repeated attempts, and you think it may be a sensor issue please contact Customer Support using the information below.
WHY DOES MY DISPLAY SOMETIMES “DROP” SENSOR DATA FROM A TIRE POSITION?
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 temperature display AND exterior temperature 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 display 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.
WHY CAN’T I SET A LOWER PRESSURE THAN 100 PSI FOR THE HIGH OR LOW PRESSURE ALARM?
The high-pressure alarm cannot go lower than the low-pressure alarm setting. If your tire pressure settings are below 100 PSI, you must
rst set the low-pressure alarm settings and then set the axles’ high-pressure settings. When done, be sure to press and release the
“SET” button to save all the parameter settings.
WHAT CONDITIONS CAUSE THE DISPLAY TO ALARM?
The display will alarm for the following reasons:
1. A rapid leak of 2 psi per minute or greater (FAST LEAK at bottom of screen).
2. A low sensor battery (upper left battery icon ashes).
3. An overheating tire, increasing the temperature (HIGH TEMP at bottom of screen).
4. A high or low-pressure reading (be sure your parameters are set correctly).
In every instance, the tire Pressure and Temperature numbers will also ash when the tire with the problem blinks.
