Failure Modes and Effects Analysis for TIU in Application Level 1 and Level 2 - Issue 3.0.12 - 2014-05-08 baseline release

Sep 10, 2026

Failure Modes and Effects Analysis (FMEA) for the TIU in Application Level 1 and Level 2 documents a structured risk analysis across control and braking functions. The modification history tracks creation and successive baseline updates, including revisions after comments, RAMS working group inputs, and safety group feedback. The table of contents organizes the analysis into operational modes and detailed FMEA items, covering mode control subtopics and brake control scenarios with supporting assumptions and an introduction.
