🔧 Have you ever wondered how an ECM tester is built? Today I’m working on a custom tester for Caterpillar ECMs, and here’s what it takes 👇 ⚡ Power supply to activate the ECM 🔌 Diagnostic port to connect and scan 🛠️ Injectors solenoids to simulate engine operation 📡 Signal generator to recreate crankshaft & camshaft timing 🎛️ Variable resistors to simulate oil pressure & RPM changes Still a work in progress… but soon you’ll see it running live. If you want to learn more about ECMs and diagn

💻 How do we test ECM performance? Before shipping an ECM to another state or country, we test it intensively, including bench testing, verifying internal signals and voltages, and testing on our engines or trucks ✅🚛 We run it to normal engine temperatures and confirm there are no issues or active codes 🔍💻 This allows us to detect issues like misfiring cylinders or smoke that a simulator cannot easily show 👀 If you have questions about ECM repairs, you can leave them in the comments 💬 #Dies
