This post compares the Autel MP900TS and MK900TS diagnostic tools, highlighting their key differences in capability and positioning. While both offer strong TPMS functions and basic diagnostics, the MP900TS delivers more advanced features—such as online ECU coding, hidden function activation, and guided functions for European vehicles—making it a better fit for professional shops handling complex electronics. The MK900TS, on the other hand, provides excellent value for tire and TPMS-focused services. In short: MK900TS is a solid TPMS-focused solution, while MP900TS is the enhanced, professional-level upgrade for broader diagnostic needs.
