With the increasing prevalence of Tire Pressure Monitoring Systems (TPMS) in automobiles, an efficient and reliable TPMS diagnostic tool has become a necessity for repair technicians and car owners. AUTEL, a leading global provider of automotive diagnostic solutions, has gained widespread market recognition for its MaxiTPMS series products, the TS508 and TS408, thanks to their excellent performance and affordable pricing. This article will comprehensively analyze the highlights and value of these two TPMS tools from three dimensions: product functions, core differences, and practical examples.

I. Product Overview

MaxiTPMS TS408 – A Powerful Entry-Level TPMS Tool

The MaxiTPMS TS408 is AUTEL's new generation of basic TPMS tools. It features a 2.3-inch TFT color display (320×240 dpi), a built-in 3200mAh lithium polymer battery, and a lightweight design (only 0.38kg), making it ideal for daily repair work.

The core functions of the TS408 include: activating TPMS sensors from all known brands, reading sensor IDs, tire pressure, temperature, and battery status; programming the AUTEL MX-Sensor, supporting three programming methods: activation copy, manual input, and automatic creation of 1-16 ID groups; and providing onboard relearning process guidance, covering all American, Asian, and European models equipped with TPMS. In addition, the TS408 also supports key remote control signal testing.

MaxiTPMS TS508 – An Advanced TPMS Service Tool

The TS508 represents AUTEL's mid-to-high-end TPMS service tools. It is a comprehensive upgrade from the TS408, offering richer and more powerful functions.

In addition to all the basic functions of the TS408, the TS508 adds the following key features: support for both Quick Mode and Advanced Mode TPMS service modes; support for reading sensor IDs via the OBD interface and copying them to the MX-Sensor; support for OBD relearning; ability to read and clear TPMS fault codes (DTCs) and display fault code descriptions on the screen; support for tire type/pressure selection; RKE (remote key) and RF (radio frequency) signal monitoring functions; and two methods for MX-Sensor programming. The TS508 is updated via USB, while the TS508WF version additionally supports Wi-Fi updates.

As the comparison shows, the TS408 is positioned as an entry-level tool, focusing on the core functions of TPMS sensor activation, reading, and programming; while the TS508 is positioned as a professional-grade service tool, with significant improvements in the depth and breadth of TPMS diagnostics.

III. Practical Application Cases

Case 1: Toyota RAV4 TPMS Warning Light Stays On – TS508WF Saves Owner $400

A 2015 Toyota RAV4 owner had been troubled by a persistently illuminated TPMS warning light. A visit to the 4S dealership revealed the need to replace the sensor at a high cost. The owner opted to purchase an AUTEL MaxiTPMS TS508WF to resolve the issue himself.

Operation Process: Using the TS508WF, the sensors on all four tires were activated one by one, quickly identifying a damaged sensor. A new AUTEL MX-Sensor was then programmed using the TS508WF and installed on the wheel. Finally, the OBD relearning steps displayed on the TS508WF screen were followed to complete the matching process.

Result: The TPMS warning light successfully went out, and the system returned to normal. The entire process not only solved the problem but also saved the owner approximately $400 in repair costs. Owner's review: "The TS508WF is well-made and fully achieved its advertised effects."

Case 2: BMW TPMS Tire Pressure Reading Abnormalities – Precise Diagnosis by TS408S

A BMW owner used the TS408S to scan the vehicle's TPMS system and found that two tires showed low pressure. However, after manually measuring with a traditional tire pressure gauge, the owner found that the actual tire pressure of all tires was exactly the same. The sensor battery status all showed normal.

Procedure: Under the guidance of Autel support community technicians, the owner followed the recommended procedure: significantly deflating the two tires showing "low pressure," then re-inflating them to the standard pressure, and finally reactivating and reading the sensor data using the TS408S.

Result: The TPMS system returned to normal readings, and the fault was resolved. This case fully demonstrates the sensitivity and accuracy of the TS408S in TPMS diagnostics, and also illustrates that the TPMS system sometimes needs to "wake up" the sensors through a correct activation and relearning process.

Case 3: Nissan Frontier TPMS Sensor Replacement – ​​TS408S Handles It Easily

A Nissan Frontier V6 4.0 SE (2008 model) owner needed to replace four TPMS sensors. He purchased four AUTEL MX-Sensor 2-in-1 (315MHz + 433MHz) sensors and programmed and installed them using the TS408.

Operation Process: Using the TS408's "Copy via Activation" function, the ID information of the original vehicle's sensors was read. The new MX-Sensors were programmed with the same IDs as the original sensors. After installing the new sensors, the matching was completed following the vehicle-specific relearning process displayed on the TS408 screen.

Result: The new sensors perfectly matched the vehicle system, and the TPMS function returned to normal. The user commented that the TS408 was "solidly built and offers good value for money."

Case Study 4: Winter/Summer Tire Replacement – ​​TS508 Simplifies Seasonal Transitions

A car owner used the TS508 for seasonal tire replacement – ​​changing summer tires to winter tires. After changing the wheelset, the TPMS warning light on the dashboard illuminated.

Operation Process: The TS508 was used to activate the sensors on the new wheelset one by one. The new sensor IDs were written into the vehicle's ECU using the TS508's OBD relearning function.

Result: The TPMS warning light went out, and the system successfully identified the new wheelset. The entire process was completed independently by the vehicle owner without needing to visit a repair shop.

IV. How to Choose: TS408 or TS508?

Which product to choose depends on your specific needs and usage scenarios:

Scenarios for choosing TS408:

Limited budget, need a cost-effective entry-level TPMS tool

Main requirements are sensor activation, data reading, and MX-Sensor programming

OBD diagnostics and fault code reading functions are not needed

Suitable for basic TPMS services for individual vehicle owners or small repair shops

Scenarios for choosing TS508:

Requires comprehensive TPMS diagnostic capabilities, including reading/clearing fault codes

Requires sensor ID reading and relearning via the OBD interface

Requires both fast and advanced service modes to handle different scenarios

Suitable for professional repair shops or technicians who frequently handle TPMS issues

Requires RKE and RF signal monitoring functions

It is worth mentioning that AUTEL provides lifetime free software updates for both products, ensuring that the tools always support the latest vehicle models' TPMS systems.

V. Conclusion

The AUTEL MaxiTPMS TS408 and TS508 are two clearly positioned and complementary TPMS diagnostic tools.
