Modules, sensors, and the terminals and wiring that connect them are primary areas of damage when impact occurs. For body shops in particular, the proliferation of electronics presents a dynamic and spiraling challenge: The traditional collision and mechanical repair realms are fusing.  \nNew vehicles equipped with innovative electronics crash, too, and then need repair, often before they are brought to a dealership, let alone an independent facility, for mechanical service. The learning curve to keep pace seems like an inbound fastball, ready to blow by traditional competencies. Coping can feel overwhelming.  \nPut bluntly, body shops cannot provide complete repair today without an understanding of intravehicle communications, network topology, wiring diagrams, scan tools, and more. We must be able to discern and correct electrical damage sustained in an accident, avoid electrical-and electronic-related comebacks, and nurture a positive brand experience for customers. For modern, forward-thinking facilities and technicians, going ostrich is not an option.  \nThink like an Engineer  \n“Electrical systems need to work as the engineers who designed them intended, and technicians must know why they work the way they were designed,” says Peter Orlando, a technician and owner of Automotive Training Technologies  \n\n| The Color-Code Legend |  |  |\n| --- | --- | --- |\n| Circuit Patterns\u003Cbr>A.

Simply put, neither of them explains the operational strategy that engineers intended. But Nissan communication network topology diagrams and wiring schematics do. They fill in the blanks that service information may not explain, or which a scan tool cannot pinpoint.”  \n“Technicians today must be critical thinkers, trained to be conversant with accessing, understanding and using network topology, wiring diagrams, and other essential tools. For example, intermittent electrical problems after a collision present unique challenges. Technicians must be capable of testing devices, wiring and systems without disturbing connections. In addition, failure to use genuine Nissan resources can limit the completeness of a  \nBecoming and remaining fully service-ready over time to provide collision repair has gotten complicated.
