Buying Guide
TPMS Programming Capabilities
The core function of any TPMS tool is its ability to program new sensors. You need a tool that can handle multiple programming methods. The Autel MaxiTPMS TS501 PRO and the TS508WF series both offer four ways to program Autel MX-Sensors: Copy by OBD, Copy by Activation, Copy by Manual Input, and Auto Create. This flexibility is vital when you are replacing a damaged sensor and the original ID is lost.
Both the TS501 PRO and TS508WF can program up to 16 sensors simultaneously. This saves significant time when you are servicing a full set of tires. Remember, these tools only program Autel MX-Sensors, not other brands. If you need to program other brands, you will need a different tool.
Relearn Methods
After programming a sensor, you must relearn it to the vehicle’s ECU. The more relearn methods a tool supports, the more vehicles it can handle. Both the TS501 PRO and TS508WF offer three methods: Stationary Relearn, Automatic Relearn, and OBD Relearn. The OBD Relearn method is a standout feature, as it writes the sensor IDs directly to the vehicle’s computer, which is faster and more reliable than other methods.
This is a major upgrade over older tools like the TS408, which lack OBD Relearn. If you work on a wide range of vehicles, having this option is a must. For a comparison of Autel with other brands, see our ancel vs autel scanners article.
Update Method and Coverage
Software updates are critical for keeping your TPMS tool compatible with new vehicle models. The TS501 PRO updates via USB, which requires a computer. The TS508WF series, however, updates directly over WiFi. This is a major convenience, as you can update the tool from anywhere with a WiFi connection without needing a PC.
Both tools offer lifetime free updates, but the WiFi capability of the TS508WF makes it much more user-friendly. If you value simplicity and speed, the TS508WF is the better choice. For a deeper dive into OBD2 scanners, visit our guide for Ram 2500.
Diagnostic and Reset Functions
Beyond programming and relearn, a good TPMS tool should help you diagnose system issues. Both the TS501 PRO and TS508WF can read and clear TPMS DTCs, check sensor health, and reset the TPMS warning light. They can also perform a full TPMS health check, which is a one-step process to assess the entire system.
This diagnostic capability is essential for quickly identifying faulty sensors or other problems. Without it, you might replace a good sensor or miss a deeper issue. The TS508WF also offers Quick Mode and Advanced Mode, letting you choose between a fast check and a complete diagnostic session.
Final Thoughts
Choosing between the Autel MaxiTPMS TS501 PRO and the TS508WF series comes down to your specific needs. For a budget-conscious user who does not mind USB updates, the Autel MaxiTPMS TS501 PRO TPMS Programming Tool offers excellent value and all the core functions you need. However, if you want the most convenient update method and a more streamlined workflow, the Autel MaxiTPMS TS508WF TPMS Relearn Tool is the superior choice, with its WiFi updates and dual-mode operation. Either way, you are getting a professional-grade tool that will handle your TPMS needs for years to come.
Frequently Asked Questions
Can the Autel TS501 PRO program sensors from other brands?
No, the Autel TS501 PRO, like all Autel TPMS tools, can only program Autel MX-Sensors. It cannot program sensors from other brands such as Bosch, Continental, or any OEM-specific sensor. If you need to program other brands, you will require a different tool.
What is the difference between the TS501 PRO and the TS508WF?
The main difference is the update method and additional features. The TS501 PRO updates via USB, while the TS508WF updates over WiFi. The TS508WF also offers Quick Mode and Advanced Mode for faster or more detailed diagnostics. Both tools share the same core programming, relearn, and diagnostic capabilities.
Do I need to update my TPMS tool regularly?
Yes, regular updates are essential to maintain compatibility with new vehicle models. Both the TS501 PRO and TS508WF come with lifetime free updates. We recommend updating your tool at least twice a year, or whenever you encounter a vehicle that is not supported. The TS508WF’s WiFi update makes this process much more convenient.
Is the TS501 PRO worth the upgrade from a TS408?
Absolutely. The TS501 PRO offers significant upgrades over the TS408, including OBD Relearn, the ability to read and clear TPMS DTCs, and tire type/pressure selection. These features save time and provide a more complete diagnostic picture. If you are still using a TS408, upgrading to the TS501 PRO or TS508WF is a worthwhile investment for 2026.
