Module Inputs and Outputs

Module Inputs and Outputs is Lesson 7 of Voltzs Module 7, Reading Automotive Wiring Diagrams. This automotive diagnostic lesson explains Sensor inputs, switch inputs, actuator outputs and references. 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 Classify each wire at a module before choosing a test. Voltzs builds this knowledge in sequence from Lesson 6: Relays and Control Logic on Schematics and prepares the learner for Lesson 8: Network Topology Diagrams. 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.
