Unfortunately, that kind of data is not included in a repair manual. MTBF (Mean Time Between Failures) s theoretical statistical data generated during the R&D phase by component suppliers (like Bosch, Siemens, or Denso) before the car is even built. It is strictly internal engineering data used by the manufacturer to validate warranty periods and predict long-term fleet maintenance costs. It is considered proprietary and is almost never published in consumer-facing or technician-facing documentation.
Service and repair manuals are fundamentally "How-To" guides written for technicians who are standing in front of a car that is already broken. Knowing that an ECU or a sensor was designed to last 50,000 hours serves no practical purpose when you are trying to repair the vehicle. A mechanic needs to know how to verify if a component has failed right now, not when it was statistically predicted to fail.
Furthermore, manufacturers would never publicly document how long a part is expected to last before breaking. Publishing a list of expected failure dates for their own components would be a PR nightmare.
Instead, this OEM software provides the practical data you need to fix the car: diagnostic flowcharts, resistance (Ohms) and voltage specifications to test those electronic components, and the detailed wiring diagrams to trace the circuits. It tells you exactly how to fix it, not when it's going to break.
