BMW diagnostics index

SSS is the Software Service Station, a dedicated workshop computer for coding, individualisation and programming. Progman is the program management software associated with the period when these tasks were moved away from direct execution on DISplus and GT1.

What changed

BMW's ST406 equipment table describes Progman CD14 as the point at which GT1 and DISplus no longer directly performed the operations and instead acted as remote terminals to SSS. The same manual's narrative describes the transition with CIP 15.0 and implementation of Progman. These are the manual's release references, so check the particular installation rather than using a single version number as an absolute cutoff.

SSS could also initiate its own requests. BMW describes a configuration capable of programming up to five vehicles at once, subject to the equipment and network arrangement. The SSS itself was not the general diagnostic tester; GT1 and DISplus remained available for diagnosis.

Interfaces and preparation

The correct diagnostic head or optical OPS/OPPS interface depended on the vehicle and operation. Read the specific vehicle procedure, use a suitable programming power supply and record the control-unit identification and software state. The later ISTA/P and ISIS/ISSS architecture is related historically but is not the same SSS system.

The BMW training manual includes an SSS equipment photograph.
