If you’re dealing with a blinking or illuminated TPMS (Tire Pressure Monitoring System) light, you might be wondering, “Can You Use A Scan Tool To Relearn The Tpms?” The answer is often yes, but it’s not always straightforward. Understanding TPMS technology, the role of scan tools, and the specific relearn procedures will help you address TPMS issues effectively.
A scan tool, especially a dedicated TPMS scan tool, can be an indispensable asset for diagnosing and resolving TPMS issues. Not only can they read and clear TPMS fault codes, but many advanced scan tools also offer relearn functionalities, making the process much smoother. Choosing the right scan tool, however, can be a challenge, given the various options available on the market. Some popular options include the tech400pro tpms scan tool.
Understanding the Role of a Scan Tool in TPMS Relearn
The TPMS uses sensors within each tire to monitor pressure and transmit data to your vehicle’s ECU (Electronic Control Unit). When a tire loses pressure, the sensor detects this change and triggers the TPMS warning light. A scan tool acts as a bridge between the TPMS sensors and you, allowing you to understand what’s happening within the system.
How Scan Tools Diagnose TPMS Problems
Scan tools diagnose TPMS issues by reading the diagnostic trouble codes (DTCs) stored in the vehicle’s ECU. These codes pinpoint the specific problems, such as a faulty sensor, low battery in a sensor, or issues with the TPMS module itself. Some scan tools, like the vt scan tool, can even display real-time tire pressure and temperature data.

How Scan Tools Facilitate TPMS Relearn
TPMS relearn is the process of teaching the vehicle’s computer the location of each TPMS sensor after tire rotation, sensor replacement, or other work affecting the tires. Many scan tools simplify this process by triggering the relearn mode, eliminating the need for manual procedures like deflating tires or using magnets. Some advanced scan tools even have the capability to program new sensors. For example, a bartec scan tool is known for its comprehensive TPMS functionality.
Different TPMS Relearn Methods
There are several TPMS relearn methods, and knowing which one applies to your vehicle is crucial. These methods generally fall into four categories:
- Stationary Relearn: The car remains stationary while the scan tool triggers the relearn mode.
- Auto Relearn: The car automatically learns the sensor IDs after driving for a specific period and under specific conditions.
- OBD-II Relearn: The scan tool is connected to the vehicle’s OBD-II port to directly initiate the relearn process. This is where a tool like the tpms scan tool autozone can be useful.
- Self Relearn: This process is similar to Auto Relearn, but doesn’t require a scan tool.
Troubleshooting Common TPMS Issues
Sometimes, the TPMS light might stay on even after relearning the sensors. This can be due to several reasons:
- Dead Sensor Battery: TPMS sensors have batteries with a limited lifespan. A dead battery necessitates sensor replacement.
- Faulty Sensor: A sensor might malfunction due to physical damage or internal issues.
- TPMS Module Issues: Rarely, the TPMS module itself can be faulty.
- Improper Installation: If a sensor wasn’t installed correctly, it might not communicate with the system.
Knowing more about automotive scan tools service functions can be beneficial in diagnosing these complex issues.
“Ignoring a TPMS light could lead to driving with underinflated tires, resulting in decreased fuel efficiency, increased tire wear, and potential safety hazards,” warns John Smith, Senior Automotive Technician at Smith Automotive Repair.

FAQ
- Can any scan tool relearn TPMS? No, not all scan tools have TPMS relearn capabilities. Check the tool’s specifications before purchase.
- How much does a TPMS relearn cost? The cost varies depending on where you get it done, but it typically ranges from $20 to $100.
- How often should I relearn my TPMS? Typically, you’ll need to relearn your TPMS after tire rotation, sensor replacement, or other work affecting the tires.
- Can I drive with a TPMS light on? While possible, it’s not recommended. Driving with underinflated tires can be dangerous.
- How long does a TPMS sensor battery last? Sensor batteries typically last 5-10 years, depending on usage.
- What happens if I ignore the TPMS light? You risk driving with underinflated tires, which can lead to poor fuel economy, increased tire wear, and potential blowouts.
- Do I need a special tool to replace a TPMS sensor? While it’s possible to replace a sensor with basic tools, specialized tools can simplify the process and prevent damage.
