The CMS collaboration is developing two-sided silicon strip modules for the second phase of the CMS outer tracker upgrade. This upgrade will enable the CMS experiment to utilize the high luminosity provided by the future HL-LHC. The modules' Service Hybrids are responsible for the high and low voltage distribution on the module and the data connection via optical links to the back-end electronics. During the production a test system for the roughly 20,000 Service Hybrids will be needed. It is designed to test all functions of the Service Hybrids during active thermal cycling. The design is centred around a dedicated test board PCB, which hosts a Raspberry Pi miniature computer, serializer/deserializer ASICs to mimic the readout hybrids' data stream, and components to test the slow control and power distribution features. The design of the system, the test software, and recent measurements with fully functional Service Hybrid prototypes are presented.
