🔥 Diagnóstico inicial REAL a una PLD de Mercedes-Benz | Consumo de corriente, CAN y K-Line

In this video, I'll show you the first step that separates a professional technician from a mere parts changer: a properly performed initial diagnosis on a Mercedes-Benz PLD. Here we perform: ✅ Current draw test to detect shorts, overloads, and abnormal states ✅ CAN signal measurement using technical criteria ✅ K-Line analysis to verify communication ✅ Real-world data interpretation, not just "measuring for the sake of measuring" This is the type of testing that prevents burning out modules, wasting hours of work, and providing incorrect diagnoses. 👨‍🏫 I'm Professor Raúl, an electronic diagnostics specialist for ECUs and PLDs, and here I'll show you how a professional diagnostician thinks from the very first second at the bench. 📲 Follow me on Instagram: @soy_elproferaul There I upload complete repairs, real-world tests, technical live streams, and different content than what I share on YouTube and Facebook. 💬 Would you like us to analyze a specific PLD in another video?
