Send the sensor a 125 KHz “continuous” wave command
signal ( ).
Send the sensor a 125 KHz “modulated” wave command
signal ( ).
Position the magnetic tool specified by the OEM in close
proximity to the sensor. The tool is provided with the
vehicle or is available from the OEM.
OmiDetect 50 can activate only sensors capable of being activated
with a continuous wave command signal, primarily Schrader
sensors. Many current-generation sensors can be activated using
that method.
Once a sensor is activated, OmiDetect will listen for the appropriate
response signal. If it detects a valid signal, it will provide both visual
and audible confirmation and indicate its frequency (either 315 MHz
or 434 MHz).
Note: Older generation sensors may not have the electronics
required to activate them using these methods.
Reprogramming
Each TPM sensor has a unique internal identification code. With
most current generation TPM systems, anytime you rotate a
vehicle’s tires or replace one or more TPM sensors, you must “reset”
(reprogram) the TPM system’s control module by placing it in the
“learn” mode and activating each sensor so the control module can
identify the new sensor locations. Refer to the Omitec TPM System
Quick Reference Guide provided with your OmiDetect system for
instructions on how to reset the TPM system of a specific vehicle
make and model.
IMPORTANT: If you do not reprogram the control module, it will
continue to report the correct tire pressures, but will assign
them to the wrong wheel locations.
Other Cases Where You Will Need to Reprogram the TPM Control
Module
If the vehicle’s battery or the TPM control module is disconnected or
the voltage to the TPM system drops below a certain value, the
control module will loose all its sensor ID information and will set a
