SRS System Architecture

SRS System Architecture is Lesson 1 of Voltzs Module 29, SRS, Airbags & Safety-Critical Electrical Systems. This automotive diagnostic lesson explains Airbag control module, crash sensors, airbags and pretensioners. It is designed to show technicians, apprentices, auto electricians and serious DIY learners not only what the system does, but how to reason through it: what to inspect first, which tool or measurement is appropriate, where a test should be made when safe, what the result can prove, what it cannot prove, and what the next diagnostic step should be. By the end, the learner should be able to Understand the system without treating pyrotechnic devices like ordinary loads. Voltzs builds this knowledge in sequence from Module entry / prerequisite knowledge and prepares the learner for Lesson 2: Pyrotechnic Device Safety. Vehicle-specific values, pinouts and procedures vary, so the full lesson distinguishes universal electrical principles from specifications that must be checked against reliable manufacturer information.
