💬🔧 How I Diagnose a Caterpillar ECM 🚛🛠️ 🚚❌🔌First, I check if the ECM powers up and communicates. If it does, I feed it the timing signals to see if injectors fire. 🔄🔧🚛I also review the communication between the ECM and the other components of the truck 📊🔌⚡Finally, use an oscilloscope to check injector pulses and other signals. And voltmeter to check the voltage of all the sensor supplies. Do you have any questions about ECM diagnostics? Put them down in the comments below! 💡❓ 👉Follo
