What Causes TPMS to Fail?

TPMS Direct explains some of the causes of TPMS failure

Sensors fail primarily due to battery failure or improper service procedures. Initially there will be a learning curve for installing and checking the Tire Pressure Monitoring System (TPMS Tool), but most service technicians quickly learn how to identify and service the system efficiently.

●   Sensor batteries can become discharged and fail – the internal lithium battery is not serviceable, and it has a life expectancy of approximately 5-7 years.
●    Installing the incorrect valve core will cause failure – TPMS sensors require a special nickel-plated valve core instead of the regular copper or brass valve core
●    Normal tire changing procedures can damage a TPMS sensor – this includes flat repairs, new tire replacement, snow tire change or a wheel upgrade
●    Pulling a typical looking rubber valve stem out of the wheel will lead to a broken sensor. TPMS systems now use either metal or rubber valves
●    Over tightening a new sensor valve will result in a broken sensor
●    Typical road hazards – collisions, potholes, curbs – can damage the TPMS system
●    TPMS sensors contain delicate electronics that are subject to failure over time

Like most things, TPMS are not invincible. Such as ATEQ VT55 OBDII TPMS Diagnostic Tool. Curbs, potholes, and just streets in general pose hazardous conditions to our aftermarket wheel and TPMS Sensors. Unfortunately we cannot control that but we can save you from the dealership! Our sensors are 100% OEM replacement, they are the same exact sensors that are in there right now. We buy in large quantities direct from manufactures to ensure that we always have availability, and that we provide the best prices anywhere.

Tool Q&A: Ready to tackle TPMS service?

Techs must know the underlying TPMS tasks: relearns, sensor failures and senor programming.

There are so many topics coming into play within the automotive industry that you would think every technician would be concentrating all their attention on. Topics like telematics, greenhouse gas reduction technologies and OBD hacking. Yet even with all of these game changers in front of us, a major buzzword still seems to be Tire Pressure Monitoring Systems (TPMS).

TPMS has been mandated by the Transportation Recall Enhancement, Accountability and Documentation (TREAD) Act since 2007 and has actually been in existence since the 1980s. Its purpose is just what its name implies. So how does it work? Sensors inside the tires monitor the pressure and tell an electronic control module (ECM). If a tire pressure is low, a warning light comes on. Seems simple, right? Yet an idea so simple, is a lot more intricate than one would think.
Q: What are the biggest issues a technician may experience with TPMS systems?

A: There are three TPMS issues that a technician will face if he works with tires: relearns, sensor failures, and sensor programming.

1) Relearns: You come across these when you do a tire rotation. Many manufacturers have each tire sensor position “learned” so when a sensor fails, the ECM knows which tire to alert you of. Every time you rotate the tires, you need to do the manufacturer specific relearn procedures in order for the vehicle to learn the new position of the tires.

Many times, technicians who skip this procedure end up having it catch up to them in the long term. For example, let’s say the technician does the tire rotation. There is no TPMS light on, so he sends it on his way. Later down the road, on a busy day (because every technician knows these things only happen on your busiest day), the customer comes in stating their right front tire is low and would like the technician to put air in it.

Guess what that technician gets to do? Check every tire, wondering which one is low. If the customer is observant, he may even ask, “why are you adding air to the right rear tire when it says the right front is low?” Now the technician has to explain that he got lazy on that customer’s prized possession the last time they were in.

So remember this every time you do a tire rotation. The vehicle may need a TPMS relearn. But remember on the plus side, it’s okay to charge extra for it

2) Failures: TPMS failures are when you have an issue with the Professional Diagnostic Tool TPMS system. This can be a mechanical failure or an electrical failure. Many failures lead to sensor replacement. Replacing sensors leads to the next issue, sensor programming.

3) Sensor Programming: Just like getting a new ECM in a car requires programming, so do TPMS sensors.

According to TPMS experts., there are two main types of aftermarket replacement sensors for TPMS. One type comes blank and needs the vehicle protocol programmed onto it, while another type comes with all manufacturer protocols built into it, and your reset tool picks which protocol you want it to use. Therefore, it is important to know what your tool is capable of so that you know the type of sensor to order from your parts supplier when replacing sensors.
Q: What would I need to be service ready for ATEQ VT55 OBDII TPMS Diagnostic Tool?

A: To be fully TPMS capable, you need to start at your parts supplier. They need to have sensors readily available for delivery. You also need to be aware of the types of sensors they have. Are they blank and in need of a protocol programmed into it? Or do they have every protocol already programmed and need selecting? The answer to this is critical for the next step.

Remember how the old adage goes, “You gotta have the right tools to do the job.” Something we technicians have had beaten into our brains since day one.

You need to have the tools to diagnose, repair, and program the TPMS systems. Manufacturers for TPMS equipment include Bartec USA, ATEQ Corp. and Bosch OTC. From the ATEQ Corp. VT55 to Bartec’s TPMS Mechanical Tool Kit to Bosch OTC’s TPMS reset tool, these  companies bring a wide variety of user-friendly, yet technologically advanced tools to the table, whether you are diagnosing faults, mechanically repairing sensor parts, or programming the sensors.
Q: Why is TPMS service advantageous in California?

A: On Sept. 1, 2010, the California Air Resources Board’s Tire Pressure Regulation came into effect, declaring that all automotive service providers must set a vehicle’s tire pressure every time they touch a car, then record their findings on the invoice. The tire pressure gauge must also be accurate within 2 PSI above or below actual pressure.

This is a free rein to inspect tires and TPMS systems! Either way, you are going to have to approach tire pressure with the customer, so why not use it to your advantage? This is where customers will see that not only did you follow the law and record their set tire pressure, but you were also proactive enough to go above and beyond to let them know how to take care of their TPMS systems, even if everything checks out fine.

So as much as people try to avoid TPMS from www.obd2tool.com, its clearly here to stay. It’s as integral a part of our diagnostics as anything else. Therefore, with proper education and tooling, TPMS can be embraced instead of questioned and shunned.

I tried to connect to E500 today. The computer says there is a fault in the cable ie Not connecting to the cars CPU. The LED light is on the Diplexer so it is getting power from the car but DAS will not find the car. The connection status says offline – red bar on connection status. I assume this is correct. Do I have to select direct cable assess to the car in the setting? i have it working now . Com port was incorrectly setup to com1 should be com2.

hi, brothers, I have bought one the mb star c3 from obd2tool several months ago, and now it works perfect for my 2001, 1998, and 2006 cars including reading out and erasing trouble code, reading the real-time data of sensor and actuator; coding and programming. You can have a try.

Do not worry about that the “china” clones are much cheaper and the quality of products are not as well as the original. Some of my friend from the Mercedes Benz club all purchased best quality C3 from the same shop. We did not find any problem with C3. We think it to be a wonderful replica. My friends and i also spent a ton of time researching for the best source to get a good replica and found few distributors on the forums. After discussion, we decided to buy C3 Star from mb star shop for it is more professional for Mercedes Benz, compared with other comprehensive websites. mbstarshop is specialized for benz vehcles. Go to have a look and you will trust me.
good luck…

The ateq vt55 obdii triggers all newly mounted TPMS sensors and turns the warning light off. It decodes the sensor data and ensures that the correct tire pressure monitoring sensor is being read and isn?t a radio frequency transmission from a key fob or other sensor. The process allows the user to display the data on screen but also to transfer it to a PC and print out results outlining which sensor is faulty and why. To use, technicians only need to select the make of the vehicle and press the “start” button to accurately activate and decode TPMS sensors and display data.
