Introduction 1. Introduction Congratulations on your purchase of the OmiDetect 50 Tire Pressure Monitoring (TPM) sensor tester. To enjoy safe and the best performance from your OmiDetect 50, 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 vehicles must comply. The total population of vehicles with TPM systems will grow from approximately 4 million units in 2003 to close to 50 million units by the end of the decade. 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 Schrader TPM Sensor Vehicle manufacturers using Schrader TPM sensors: Ford Chrysler GM Infiniti Mitsubishi Nissan Saab Volvo 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. Using their piezoresistive technology, they monitor tire pressure via measuring the deformation of an internal diaphragm.
Introduction 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.
Introduction DTC for a TPM fault. In this case, you will need to reprogram the control module and clear the DTC. Figure 1. OmiDetect shown in use in testing a TPM sensor.
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. Be sure to retain this cap for reuse. 8. Strong radio waves may interfere with the proper operation of some TPM systems. 9. Snow, ice or mud in the wheel wells and tire chains mounted on the tires may cause a TPM system to malfunction.
Safety Information Kit Contents Your OmiDetect 50 kit includes: OmiDetect 50 TPM Sensor Tester 9V 6LR61 Battery OmiDetect 50 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 3. Controls and Indicators OmiDetect’s display has a series of 6 LEDs and a Low Battery Indicator LED. Figure 2. OmiDetect 50'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. The second LED (2) indicates the TPM sensor mode. In this mode OmiDetect will activate a Schrader valve by transmitting a continuous RF signal.
Setup Procedure Keypad Buttons Press to power On/Off the tester and to select TPM sensor Mode. Also lets you select the “Listen” mode to test sensors activated manually, rather than electronically using OmiDetect. Press to start testing, causing OmiDetect to activate the TPM sensor and listen for a valid response RF signal from it. 4. Operating Instructions When operating OmiDetect to test a Schrader TPM sensor for proper operation, you will always perform these steps: 1.
Setup Procedure RF signal to penetrate the sidewall is small, carefully aim OmiDetect halfway between the tire rim and the tire tread. 3. Power On the OmiDetect tester, by pressing and holding down the power On/Off button for 2 or 3 seconds. You will hear a beep and the LED array will illuminate and display the last test mode used. 4. Select TPM sensor mode by pressing the power On/Off button until the LED under the Tire symbol illuminates.
Setup Procedure Once OmiDetect detects the appropriate response signal, it will beep 3 times, the LEDs will stop flashing, and the LED for the frequency of the response signal it detected (either 315MHz or 433MHz) will illuminate for 5 seconds to indicate the sensor is operating properly. If it does not detect the appropriate signal, you will hear a continuous beep and the X LED will illuminate continuously, indicating the sensor is not operating properly.
Setup Procedure 5. 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. Technique A 1. Depress the tire’s valve stem to release air pressure for about 5 to 8 seconds. The TPM sensor will detect the loss of tire pressure, causing it to transmit a signal to the vehicle’s TPM control module. 2.
Setup Procedure If OmiDetect detects a valid signal, it will beep 3 times and illuminate the appropriate signal frequency LED for 5 seconds. 6.
Setup Procedure When finished activating all the TPM sensors, you may be required to drive the vehicle a specified distance and speed in order for the 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. 7. Vehicle Coverage Guide OmiDetect 50 can test only vehicles fitted with Schrader TPMS sensors.

Setup Procedure 8. Specifications TPMS Valve Sensor Activation Inductively Coupled RF at 125KHz Activation Range 2” – 8” (50mm – 200mm) depending on sensor and wheel type Activation Format Continuous Frequency RF Detection Frequencies 315 MHz & 433.92 MHz Power 9V Battery (Alkaline/Manganese) PP3, IEC 6LR61 or 6F22 Note: Do not use rechargeable batteries. Dispose of used batteries in accordance with local authority guidelines. Approvals FCC This device complies with Part 15 of the FCC rules.
Troubleshooting 9. Troubleshooting 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.
Operating Tips sound a constant tone and illuminate the Low Battery Indicator LED (see Sec. 3) for 5 seconds, then the system will automatically power Off. Problem: OmiDetect will not power On. Possible solution: The tool’s internal 9 volt alkaline battery may be low and need to be replaced (see above). 10. Care and Maintenance Your OmiDetect system should be cared for like any other piece of high-quality electrical equipment.
