1. What Exactly is TPMS and When Was It Introduced?

TPMS, an abbreviation for Tire Pressure Monitoring Systems, was first adopted voluntarily by brands like Porsche and Cadillac. However, it became a requirement for all cars and light trucks starting September 1 under the TREAD Act. This regulation mandates that manufacturers equip vehicles with systems that can identify and alert drivers to tires that are under-inflated by 25% or more.

2. Is TPMS a Reliable Safety Feature?

Yes, it is. Research from the National Highway Traffic Safety Administration suggests that TPMS saves around 660 lives annually, a reduction in injuries by 33,000 individuals, and conserves nearly $511 million in fuel costs.

3. What Does a Steady vs. a Flashing TPMS Light Mean?

A steady TPMS light shows that at least one tire is under-inflated. When the air pressure is adjusted to the specified level, the light should turn off. In contrast, a flashing TPMS light signifies an issue with the tire pressure monitoring system itself, which typically transitions to a steady light after about 30 to 90 seconds of operation.

4. How Does TPMS Operate?

There are two types of TPMS: direct and indirect systems. A direct system has sensors on each tire that measure the air pressure and relay that information to the TPMS module. If the pressure deviates by 25%, a warning light is triggered. High-end systems even show which tire is low. The indirect system relies on the anti-lock braking system’s wheel speed sensors, comparing the speed of the tires to detect any discrepancies.

5. What is Required for Servicing a Direct TPMS?

Servicing a direct TPMS primarily focuses on inspecting the sensors for any visible damage or corrosion, which can occur due to exposure to various elements. Utilizing a TPMS tool to check battery life is essential, as sensors typically last around five to seven years. In the case of faulty sensors, you must remove the tire to replace them, ensuring the new sensor is correctly programmed to the vehicle.

6. What Types of TPMS Sensors Exist?

There are three main types of aftermarket sensors: direct replacement, multi-protocol, and programmable. Direct replacement sensors are pre-programmed, while multi-protocol sensors accommodate multiple vehicle types. Programmable sensors need to be configured using a TPMS tool.

7. What are the Three Relearn Methods?

Relearn processes can vary by vehicle. The three methods—stationary, dynamic, and OBDII—each have specific procedures. Stationary methods engage the vehicle in 'relearn' mode, while dynamic methods require driving for a certain distance. The OBDII method connects a tool to the car’s OBDII port for programming.

8. What Do You Need to Offer TPMS Services?

To successfully offer TPMS services, businesses should invest in a dedicated TPMS tool, sensors, and rebuild kits. A notable recommendation is from foxwell which provides comprehensive solutions for TPMS servicing. With a long-standing reputation in the diagnostic tool industry, **Autel** also offers TPMS tools well-known for their usability and effectiveness.

9. What is the Leading Cause of Sensor Failure?

Corrosion from road salts and moisture can damage sensors, leading to failures. It's crucial to ensure proper maintenance to avoid such pitfalls.

10. How Long Do TPMS Batteries Last?

The lifespan of TPMS batteries varies significantly based on environmental conditions and usage. Some can last up to 10 years, while others may only withstand three to five years.
