Automotive Control Module High-Temperature In-Line Functional Test System
This public case uses the title Automotive Control Module High-Temperature In-Line Functional Test System, with TCM / TCU Project retained as an internal tag. The source material has a TCM vs TCU naming inconsistency and is recorded in content-review. The approximately 82°C environment is presented as Project Environment, not as a general equipment operating temperature.

Engineering Challenges
- Environmental conditions and in-line functional testing need to be integrated in one test solution.
- Load simulation, measurement and CAN communication need real-time coordination.
- The test system must fit a special production environment, not a standard lab setup.
Implementation
- The architecture is organized around high-temperature environment, load simulation, electrical measurement, PWM and CAN.
- Fixture and interface systems connect the DUT and support in-line functional validation.
- Test software records process data and results for production judgment.
Engineering Outcome
- An in-line functional test system was built for a special environment.
- Project experience covers functional test requirements in an approximately 82°C environment.
- The system integrates environmental, functional, load and communication capabilities.
