CAN Termination

CAN Termination is Lesson 4 of Voltzs Module 21, Network Fundamentals & CAN Bus. This automotive diagnostic lesson explains 120 Ω terminators, parallel equivalent around 60 Ω on many correctly terminated HS-CAN networks and vehicle-specific caveats.. 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 Explain termination and interpret resistance only with correct topology/power state. Voltzs builds this knowledge in sequence from Lesson 3: Dominant and Recessive States and prepares the learner for Lesson 5: CAN Resistance Testing. 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.
