Who We Are
TCI Truck Connect Info LLC is dedicated to building powerful, easy-to-use diagnostic tools for the heavy-duty trucking industry. Our mission is simple — give drivers, mechanics, and fleets instant access to the data that matters most.
The TCI ECM Pocket Reader works with iOS and Android devices and supports most makes and models of heavy-duty semi-trucks. By combining reliable hardware with a powerful mobile app, we make advanced truck diagnostics faster and more accessible than ever.
Our Vision
At TCI Truck Connect Info, we believe truck data should be simple, accessible, and actionable. Too often, critical vehicle insights are locked behind complex tools or expensive systems. We’re changing that by putting powerful diagnostics directly into the hands of drivers, technicians, and fleet operators. By combining modern mobile technology with real-world trucking needs, we deliver fast, reliable insights that help reduce downtime, improve decision-making, and keep trucks moving. Our goal is to make advanced diagnostics effortless — one scan at a time.
