By Scot A. Holloway. Tire Pressure Monitoring Systems are and have been a required feature on U.S. Passenger vehicles since . Introducing this technology to the way we maintain our vehicles has improved safety and vehicle performance, increased fuel efficiency and tire life. It also has forever changed the way autos and tires are serviced. Any operation that works on tires has been faced with serious challenges to the way they do business. Thus is the nature of change. You can either run from it (lose business) or embrace it and seize the opportunity to grow and enhance your business.

There are some obvious questions that you may ask. Should I get involved with TPMS? Should I invest in the tools and training? What will it mean to my business? For the purpose of this article, we are going to assume that you have dealt with many of these questions and you are at the point of taking on this opportunity and now question whether or not you need a TPMS Tool.

Before I answer that question, let&#;s consider three important points. First, know that there nearly a quarter of a billion TPMS Sensors currently in use. Better than a third of those are at least 3 years old. Even more there are a large number of sensors that are on wheels that are ready to have the tires changed. There is a growing population that very soon will have battery issues. The bottom line is, if you haven&#;t already, you will soon have TPMS vehicles in your garage or repair facility.

Secondly, you need to understand the types of re-learn procedures that you face. 25% of the vehicles have a Stationary method. The Stationary re-learn requires an activation tool and the car to be in a special re-learn mode. A series of key cycles or button pushes will put these cars into learn mode so you can then use an activation tool to trigger the sensors and program the sensor ID&#;s into the control module. The challenge this method presents is the need to know all the different methods to get the car into learn mode.

Some vehicles can &#;auto-learn&#; or &#;self learn&#; new sensor ID&#;s. Essentially by driving the car after replacing the sensor, the car will assume a new ID is present after a pre-determined number of consistent transmissions from the sensor. The big issue here is time and driving. You can either drive your customer&#;s car until the light turns off or send your customer away with the light on, without knowing for certain that the light has gone off.

The last method requires an OBD Connection. Theses re-learns require that the sensor ID&#;s be programmed to or &#;written to&#; the TPMS control module directly. This is typically done with a Scan Tool or a COMBINATION Activation/Scan Tool. This method closely resembles the process used at the auto assembly line. Sensor ID&#;s are captured directly by activation (TPMS tool) and then connected to the OBDII port to write them (scan tool). This is the preferred method of re-learn as it is accurate and fast!

Finally, you need to know that your competitors are buying into this technology. Whether your competition is an OE dealer or another automotive service facility, they have the necessary tools to properly service TPMS vehicles. You can ill afford to let your competitors have the &#;leg up&#; on this emerging service. Having the ability to &#;turn out the TPMS light&#; will not only give you the ability to keep your customers happy but more importantly keep them from going to your competition.

So the answer to the question on whether or not you need a TPMS tool is simply yes. The majority of cars and trucks with TPMS require at a minimum an activation tool. A growing number of vehicles need a combination tool to get the ID&#;s programmed to the car. The best solution is a combination tool that handles all three types of re-learn situations, using the same process. A Bartec sales rep can tell you more about such tools.

When is TPMS Sensor Calibration Needed?

Today, let's learn about the definition of calibrating tpms sensors, the process, tools and under what circumstances we need to calibrate tpms sensors!

What does calibrate TPMS mean?

Calibrate TPMS (Tire Pressure Monitoring System) refers to the process of adjusting or setting the reference value of the TPMS sensor in the tire of the vehicle. During calibration, the system establishes a baseline reference for each tire's "normal" or correct tire pressure. This baseline is used to compare real-time pressure readings from the TPMS sensor.  If the actual pressure reading deviates significantly from the established reference value,  The warning light on the instrument panel may be triggered, and the TPMS system uses this method to alert the driver that there may be a problem with tire pressure.

Do TPMS sensors need calibration?

Many people wonder whether the TPMS sensor needs to be calibrated? Of course! TPMS sensors require calibration in some cases. Proper calibration ensures that the sensor measures tire pressure accurately and provides reliable data to the vehicle's onboard computer. The following situations require calibration of the TPMS sensor:

1. Tire replacement: When replacing a tire, we need to calibrate the new tire to ensure that the new sensor can be recognized and its readings are accurate. New tires may have different sensor codes, or may need to be associated with the correct TPMS sensor.

2.  Tire Rotation: Swapping a tire to a different position on the vehicle, the TPMS sensor needs to be recalibrated to match the new tire position. This is critical to maintaining accurate pressure readings.

3. Replacing the wheels: Replacing a vehicle's wheels will most likely involve replacing the TPMS sensor. In this case, calibration is necessary to associate the new sensor with the correct location and ensure accurate readings.

4. Incorrect readings are suspected: If inaccurate TPMS readings are suspected, calibrating the sensor can help reset its reference value and improve accuracy.

Not all TPMS systems require manual calibration, some vehicles have automated systems that can calibrate themselves and recognize new sensors without human intervention. Consult your vehicle's owner's manual or seek the direction of a qualified technician before calibrating your TPMS sensor.  Properly performed calibration of TPMS sensors can help drive safely, optimize tire performance and improve fuel efficiency.

How to calibrate tpms sensor&#;

Calibrating the TPMS sensor involves the following steps:

For more information, please visit TPMS Sensor Tool.

&#; Initialization: Starts the calibration procedure, which may vary by brand and model. This could include turning the ignition key to a specific position, following a specific sequence, or using a specific tool.

&#; Learning reference value: TPMS system needs to "learn" the current tire pressure reading as a new reference value. This is usually done when the tires are at the correct pressure level.

&#; Sensor identification: If the tires have been replaced or moved, the system may identify the TPMS sensor opposite to each tire position. This ensures accurate readings for each tire.

&#; Reset System: Clear any existing error codes or warnings and start over with recalibrated sensor data.

&#; Verification: After calibration, some systems may require you to drive the vehicle at a specific speed to verify the sensor readings.

Properly calibrated TPMS sensors help maintain accurate tire pressure readings, and proper tire pressure is important for safe driving, optimal fuel efficiency, and extended tire life.

What tools can we use when calibrating TPMS sensors? Some vehicles come with an automatic TPMS system that does not require manual calibration, while others may require specific tools for manual calibration. Here are some tools available for TPMS sensor calibration:

Tire pressure detection system tools:

Some vehicles require a dedicated TPMS tool to initiate the calibration process. These tools can communicate with TPMS sensors and the vehicle's on-board computer to perform tasks such as sensor identification, resetting reference values, and more.

OBD-II Scanner:

There are some advanced OBD-II (On Board Diagnostics) scanners that can communicate with TPMS systems and provide calibration. Connect the scanner to the vehicle's OBD-II port to perform various diagnostic and programming tasks, including TPMS calibration.

Dealer-specific software:

Some vehicle calibration procedures may require specific software provided by the vehicle manufacturer. The software can be accessed through a reseller or authorized service center.

Vehicle control:

For some vehicles, the TPMS calibration can be initiated with a specific button or control on the dashboard, steering wheel or center console. The vehicle's owner's manual will provide instructions on how to use these controls for calibration.

Today, many modern vehicles are equipped with automated systems that recognize new sensors and automatically adjust reference values. If you are unsure of the tools needed for TPMS sensor calibration on your particular vehicle, consult your vehicle owner's manual or consider seeking assistance from a professional mechanic or dealer. Using the correct tools and following the correct procedures will ensure that the calibration is done accurately and safely.
