Tech 500
User Guide rev1.0
JUNE 2013
28
A TPM sensor that uses the same LF activation as the correct sensor for the Make, Model, and
Year selected has been found. Since there are many TPM sensors that look alike, it can be easy
to fit the wrong sensor, or have been supplied the wrong sensor.
If you get a ? during testing, verify the MMY you have selected as well as the sensor part
number that was fitted.
Sensor Not Found Response
If the search period expires without reading a TPM then the Tech500 will emit a single Audible
Beep and indicate on the display that no TPM was found.
The TPM Data will still be stored but will indicate that the
TPM Failed to Read if the sensor fails 3 times.
