Highlights
The MS909S2 is an advanced automotive diagnostic tool, designed for professional technicians, offering powerful features and exceptional performance. Unlike the UltraS2 and MS919 S2 , the MS909S2 omits oscilloscope with the multi-purpose MaxiFLASH VCMI2, but instead comes with the MaxiFlash VCI2, which supports essential protocols like D-PDU, RP1210, CANFD, J2534, and DoIP. This ensures compatibility with both modern and older vehicles, making the MS909S2 a versatile tool for any garage. Whilst the MS909S2 does not have an oscilloscope, unlike the Ultra S2 & MS919S2, it does have all other advanced software features found on Ultra S2.
The MS909S2 offers comprehensive diagnostic functions, including diagnostics, service resets, live data streaming, and ECU re-flashing. Technicians can access real-time vehicle data and perform various tasks, from reading and clearing codes to ECU reprogramming. One of it’s stand-out features is the advanced programming capabilities for BMW and Mercedes-Benz vehicles. The MS909S2 enables tasks such as ECU adaptation and coding, all directly through the tool’s software.
The MS909S2 features innovative Topology Mapping V3, which provides a visual, colour-coded display of the vehicle’s control module network. This helps technicians quickly identify communication issues between modules, streamlining diagnostics and improving troubleshooting efficiency. With secure gateway compatibility, advanced diagnostics, and intuitive software, the MS909 is a comprehensive tool for modern automotive repair shops, providing reliability and versatility for a wide range of vehicles.
* An up-to-date software subscription is required to access Secure Gateways, DoIP and CAN-FD.
