Problem: Unable to activate a TPM sensor.
Possible solution: Confirm that the vehicle is equipped
with Schrader TPM sensors. Remember: OmiDetect
50 can activate only sensors capable of being
activated with a continuous wave signal command.
Possible solution: When aiming OmiDetect, be sure to
hold it on or close to the tire wall where it meets the
wheel rim, directly below the sensor. Do not aim
directly at the valve stem, since it is metal and will
impede receiving a good RF signal from the sensor.
Possible solution: If you are testing/activating a TPM
sensor fitted to a low-profile tire/wheel, be sure to
carefully aim OmiDetect at the tire sidewall area
halfway between the tire rim and the tire tread.
Possible solution: If you are testing an older-generation
sensor, you may have to activate it magnetically,
rather than electronically using OmiDetect. Refer to
the Omitec TPM System Quick Reference Guide or
to the vehicle manufacturer’s appropriate service
information to confirm the type of sensor installed on
the tire/wheel and how you activate it.
Possible solution: The sensor may be defective and have
to be replaced.
Problem: Inconsistent test results.
Possible solution: OmiDetect will not indicate a valid test
result when the battery is low (see Sec. 0).
Problem: OmiDetect power’s Off shortly after I power it On.
Possible solution: As a battery life saving feature, if you
do not select a sensor type within 30 seconds of
powering on OmiDetect, it will assume no testing is
required and automatically power itself Off. Also,
once OmiDetect completes a test cycle, it will
indicate whether it detected a valid signal and then
automatically power itself Off after 5 seconds.
Possible solution: The tool’s internal 9 volt alkaline
battery may be low and need to be replaced. When
the battery is low, after you power the tool On, it will
