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. OmiDetect is a state-of-the-art tester designed especially for automated and manual testing of Schrader TPM valve sensors for correct operation. Used properly, it will allow you to quickly:
Confirm that the vehicle’s Schrader TPM sensors are working properly before you start tire/wheel service work (including rotating, changing or balancing tires/wheels). This will reduce the risk of your having to replace a sensor that was defective prior to your starting the work.
Confirm that the vehicles Schrader TPM sensors are working properly after you complete tire/wheel service work.
After rotating the vehicle’s wheels, activate their Schrader TPM sensors to allow the vehicle control unit monitoring the TPM sensors to identify their new location.
Diagnose problems with Schrader TPM sensors and other TPM system components.
Confirm that a Schrader TPM sensor you replaced is working properly.
Confirm that you installed the correct type of sensor. History of TPM Systems In the wake of tire safety issues involving SUVs in the late ‘90s, Congress passed the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act in 2000. The TREAD Act mandated that automotive manufacturers start phasing TPM systems into all their new light vehicles with a GVWR of 10,000 pounds or less beginning in November 2003. By 2006, 90% of all light vehicles are to comply, and by Sept. 1, 2007, all new light Introduction 3 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. Testing showed that proper tire inflation significantly improves vehicle handling safety, decreases tread wear, improves fuel economy, and decreases stopping distances. Underinflated tires are dangerous because they build up internal heat that can damage the tire structure, potentially resulting in fatal blowouts. Direct Versus Indirect Systems The NHTSA’s mandate on TPM systems allows two system architectures. The first, called the “direct” system, uses a direct RF link from each wheel to a central receiving control unit, and the second, called the "indirect" system, works in conjunction with the vehicle's antilock-braking (ABS) system.
Direct Systems. Wireless sensor in or on each wheel that measures internal tire air pressure and temperature separately and communicates the readings by RF signals to a receiver/controller control unit at regular intervals. The sensors have an integral low frequency transmitter and are typically built into or mounted on the valve stem. The end of the valve stem serves as the sensor’s antenna. Most direct systems share the receiver control unit with the vehicle’s keyless entry system.
Indirect Systems. Monitors rotation of tires via the vehicle’s antilock braking system (ABS) to calculate whether they are properly inflated. Does not measure tire pressure or temperature. The system measures the wheel speed of all four tires and calculates a “rolling circumference” for each one. In the event of a tire pressure loss, the rolling circumference of that tire is reduced, producing a …

Description of EUT The equipment under test is an OmiDetect 50, which allows a technician to check that the basic function of an RF Transmitter in a Tyre pressure monitoring sensor is working correctly. The OmiDetect 50 achieves this by activating the valve with a 125 kHz signal for a period of 11 seconds. The signal will be continuous. The OmiDetect will then monitor the 315 MHz and 433.92 MHz ISM bands for activity. 2.4. Modifications Incorporated in the EUT During the course of testing the EUT was not modified.
