These may include “programmable”, “universal” or “cloneable” sensors. Some aftermarket sensors require special programming to meet the vehicle’s application specifications prior to installation and relearn. Sensor programming is an extra TPMS service step With the exception of some Chrysler and Mazda models that may be relearned to the vehicle via a driving procedure, a TPMS scan tool is required to complete the vehicle relearn procedure. The relearn procedure is mandatory to ensure that not only the replacement TPMS sensor works properly, but also the vehicle’s complete TPMS system functions properly as well. Vehicle relearn is a standard TPMS service stepĮvery TPMS sensor must be “relearned” to the vehicle following the prescribed OE relearn procedure after replacement, regardless of whether it is genuine OE or aftermarket. This misconception can lead to service comebacks and customer complaints. Unfortunately, some shops overlook the necessary relearn step mistakenly believing the sensor programming did the trick. These sensors must be programmed with the proper protocol/application information for the vehicle before they can be installed in the tire, and then must be relearned to the vehicle. The issue stems from the availability of aftermarket TPMS sensors that come as “programmable”, “universal” or “cloneable” sensor units. Vehicle relearn and sensor programming are completely different procedures. In spite of all the training programs and technical articles on the subject, there is still a lot of misunderstanding about TPMS, and the confusion between vehicle relearn and sensor programming tops the list. The KTI PST is also upgradeable so that the newest pulse modulated formats can be downloaded into the tool assuring its long-term usefulness.Servicing TPMS equipped vehicles profitably can be a challenge without the knowledge, the right parts and the right tools. It is designed to stand up to harsh shop environments and will resist numerous oils and fluids found in many shops. The KTI PST is cost effective and simple to use. This tool accommodates both magnetically and electronically triggered tire pressure sensors. The patented technology of the KTI PST tool eliminates the need to purchase multiple TPM tools. This results in the requirement for service facilities to purchase multiple TPM service tools. Each TPM manufacturer has designed a service tool for their specific sensor. Additionally, multiple frequency bands are used to carry the transmitted signal to the vehicle control module. There are a number of different TPM sensors manufactured today with various triggering techniques including magnetic and electronic frequency sensor initiation. Each time the tires/wheels are rotated, the sensors need to be retrained with their new position, thereby requiring the need for a tool that "triggers" the transmitter at the appropriate time during programming. This approach incorporates the use of a transmitter built into the valve stem that transmits information (Inflation pressure, sensor id, temperature, etc.) to the vehicle control module. Many automobile manufacturers have selected the direct approach. The Federal law requiring new passenger vehicles to be outfitted with Tire Pressure Monitoring (TPM) Systems has produced a wide variety of solutions.
