Congratulations on your purchase of the OmiDetect 100 Tire Pressure Monitoring (TPM) sensor tester. To enjoy safe and the best performance from your OmiDetect 100, please read and follow all instructions, recommendations and warnings. Understanding the basics of tire pressure monitoring systems is essential to using the OmiDetect effectively, so be sure to review the following sections thoroughly.
Introduction The NHTSA, which is responsible for establishing and enforcing vehicle safety standards, published a mandate requiring that the TPM system must be capable of monitoring all four tires and alerting the driver if a tire is under inflated by 25% or more of the OEM’s recommended tire pressure.
Introduction Examples of TPM sensors used in today’s direct TPM systems. Siemens Beru Pacifica Audi Chrysler Lexus Volkswagen Dodge Honda Toyota Bentley Jeep Acura Bugatti Mazda Hyundai Suzuki Ferrari Land Rover Maserati Mercedes-Benz Porsche About Sensors TPM sensors are micromechanical devices (a silicon-based vacuum cell) powered by a lithium battery with a minimum life expectancy of up to 10 years.
The OmiDetect 100 uses only ‘modulated’ wave command signals to test valves. Once a sensor is activated, OmiDetect 100 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).

Introduction 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 DTC for a TPM fault.
Safety Information 2. Safety Information IMPORTANT SAFETY NOTICE For your safety, read this manual thoroughly before operating your OmiDetect system. It is intended for use by properly trained professional automotive technicians. The safety messages presented below and throughout this user’s manual are reminders to the operator to exercise care when using it.

Safety Information 6. Never clean a TPM sensor/transmitter with compressed air or steam. Damage to the sensor/transmitter may result. 7. The cap on the valve stem or a TPM sensor/transmitter frequently contains a O-ring to prevent contamination and moisture from entering.
Safety Information 3. Kit Contents Your OmiDetect 100 kit includes: OmiDetect 100 TPM Sensor Tester 9V 6LR61 Battery OmiDetect 100 User’s Manual OmiDetect’s internal 9 volt battery Important: Your OmiDetect system’s internal 9 volt alkaline battery must have sufficient charge for the system to work properly. If it drops below the minimum required, after you power the tester on, it will sound a constant tone and illuminate the Low Battery Indicator LED (see Sec.
Setup Procedure 4. Controls and Indicators OmiDetect’s display has a series of 6 LEDs and a Low Battery Indicator LED. Figure 2. OmiDetect's LED Display. The 6 LEDs have three functions: The first LED (1) illuminates when the “Listen” mode is selected, letting you test a TPM sensor activated manually, rather than electronically using OmiDetect.
When operating OmiDetect to test a TPM sensor for proper operation, you will always perform these steps: Identify the vehicle’s TPM sensor type. (Refer to the Omitec TPM Sensor Vehicle Application Guide or to the vehicle manufacturer’s appropriate service information to identify the type of sensor installed on the vehicle.)

Setup Procedure Important: Do not aim directly at the valve stem. Since it is metal, it will impede receiving a good RF signal from the sensor. With low-profile tires, since the area for the RF signal to penetrate the sidewall is small, carefully aim OmiDetect halfway between the tire rim and the tire tread.

Also, remember that some sensors cannot be activated electronically and must be activated magnetically. (Refer to the Omitec TPM System Quick Reference Guide for information on whether the sensor must be activated magnetically.) Since the vehicle manufacturers are constantly adding new sensor protocols, the sensor may have a new signal protocol not yet supported by OmiDetect.

Setup Procedure If necessary, you can activate a sensor manually using one of the techniques outlined in the following section. To cancel a test once it has started, simply press and hold down the Power On/Off button for 3 seconds. OmiDetect will then automatically power itself Off.
Setup Procedure 6. What to Do If OmiDetect Cannot Activate the TPM Sensor If OmiDetect is unable to activate a TPM sensor, you can use either of the two following techniques to manually activate it to allow you to test it for proper operation.
Place the vehicle’s TPM control module in the “learn” mode. (The procedure required varies with vehicle makes and models. Refer to the Omitec TPM System Quick Reference Guide provided with your OmiDetect system for the procedure required for the vehicle you are servicing.) Activate each TPM sensor (see Section 5), following the vehicle manufacturer’s requirements for the order in which...
TPM control module to store the current tire pressures as new setpoints to be monitored. Refer to your Omitec TPM System Quick Reference Guide for more information. 8. TPM Sensor Type Selection Chart Refer to this chart for the combination of LEDs to be illuminated to activate the type of TPM sensor under test.
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.
The system does not need any adjustments or calibration. 12. Warranty The OmiDetect 100 TPM Sensor Tester has a one-year warranty against defects in workmanship and materials (excluding batteries). Any defective item returned within this time showing signs of abuse, tampering, neglect...
