Modern scan tools offer a “tech-to-tech” remote assistance feature, similar to “phone a friend.” This allows experts, like my BMW mechanic friend in California, to remotely connect to and control my scan tool in Ohio. I initiate the connection, send him a code, and he gains control, seeing all the diagnostic screens. This built-in protocol from the scan tool company is more reliable than previous solutions like TeamViewer. The feature also works in reverse, allowing me to help him with a Ford in California. The process is simple: access the “tech-to-tech” screen, agree to the terms, add the contact, and ensure their scan tool is online. This enables technicians to easily collaborate and fix vehicles.
