🔧 Caterpillar C15 ECM on the bench! This ECM was previously "repaired," but it's still having issues. 🚫Inside, we found loose components held with silicone and tape, definitely not the right way to fix it. 🛑We tested it before opening, and all 6 injector codes showed up, confirming it's bad. ⚡Follow me for more ECM repairs. 💡 #Caterpillar #ECMRepair #ECMDiagnostics | Oscar Truck ECM
