You are in the middle of a tire rotation, and the TPMS warning light refuses to go out. Or perhaps a customer’s sensor has a dead battery, and you need to program a replacement fast. This is where a dedicated TPMS programming tool becomes indispensable. In this review, we evaluate the Autel MaxiTPMS TS501 PRO and its close relatives, including the TS508WF and the TS408, to help you choose the right tool for your work in 2026. We cover their key features, differences, and which technician each model suits best. For a broader look at diagnostic tools, check out our guide on the best car diagnostic tools for all cars.
Buying Guide
TPMS Programming Capability
Not all TPMS tools can program sensors. The TS501 PRO and TS508WF models allow you to program Autel MX-Sensors (315 and 433 MHz) using methods like Copy by OBD, Auto Create, and Copy by Activation. The TS408 also programs MX-Sensors but lacks the Copy by OBD method, which writes the original sensor ID directly from the vehicle’s ECU. If you frequently replace sensors and need the fastest workflow, a tool with Copy by OBD saves significant time.
Relearn Methods
After replacing a TPMS sensor, you must relearn it to the vehicle. The TS501 PRO and TS508WF offer three relearn methods: Stationary, Automatic, and OBD Relearn. The TS408 only offers Stationary and Automatic Relearn. OBD Relearn is the most reliable method because it writes the sensor IDs directly to the vehicle’s ECU, ensuring the warning light stays off. For shops that service a wide range of vehicles, having OBD Relearn is a major advantage.
Diagnostic Depth
A TPMS tool can do more than just read sensor IDs. The TS501 PRO and TS508WF provide full TPMS diagnostics, including reading and clearing TPMS DTCs, performing a one-step health check, and displaying on-screen DTC descriptions. The TS408 is a more basic scanner that activates and reads sensor data but does not offer OBD diagnostics. If you need to troubleshoot the entire TPMS system, not just replace sensors, invest in a model with full diagnostic capability.
Update Method
Software updates keep your tool compatible with new vehicle models. The TS508WF models update via Wi-Fi, which is the most convenient method. The TS501 PRO updates via USB. The TS408 also updates via USB. Wi-Fi updates save time and eliminate the need for a computer. For a tool that stays current with minimal effort, a Wi-Fi update model is the best choice.

Final Thoughts
Choosing the right TPMS tool depends on your specific needs. For the technician who wants the most complete package with Wi-Fi updates, full diagnostics, and all programming and relearn methods, the Autel MaxiTPMS TS508WF TPMS Relearn Tool is the clear winner. If you are on a tighter budget and still need professional-grade programming and diagnostics but can manage with USB updates, the Autel MaxiTPMS TS501 PRO TPMS Programming Tool offers exceptional value, delivering the same core functionality as the TS508WF at a lower cost.
Frequently Asked Questions
Can the Autel MaxiTPMS TS501 PRO program sensors from other brands?
No. The TS501 PRO, like all Autel TPMS tools in this lineup, can only program Autel MX-Sensors. It cannot program sensors from other brands. You must purchase Autel MX-Sensors for programming.
What is the difference between the TS501 PRO and the TS508WF in 2026?
The main difference is the update method and the addition of Quick and Advanced Modes. The TS508WF updates via Wi-Fi, while the TS501 PRO uses USB. The TS508WF also offers two operating modes for faster workflow. Both have the same core TPMS functions, including programming, relearn, and diagnostics.
Does the TS408 support OBD Relearn?
No. The TS408 only supports Stationary and Automatic Relearn. It does not have the OBD Relearn function, which is available on the TS501 PRO and TS508WF. OBD Relearn is the most reliable method for turning off the TPMS warning light after sensor replacement.
Do I need to update the tool before first use?
Yes. Autel recommends registering the tool and updating the software to the latest version before using it. This ensures compatibility with the newest vehicle models and unlocks all available features. For a deeper look at Autel’s TPMS tools, see our autel MaxiTPMS TS501 update review.
