🔧 ECM Diagnostics: Method 2 🔧 Discover the second method to diagnose an ECM! Here's an example on a Detroit DDEC III 1️⃣ Connection: We hook the ECM to a bench harness for communication. 2️⃣ Diagnostic Codes: We used Detroit Diagnostic Link and found it has non-volatile memory failure and zero engine hours. 3️⃣ Result: This DDEC III ECM (12.7 Detroit) needs repair—100% confirmed! 🔍 Advanced Testing: I also manually check voltages and inspect signals in our lab for injector or sensor issues us

🔴Exploring 12.7 Detroit ECM Damage This is a Detroit Series 60 engine DDEC IV ECM. ✅This ECM had a seal that looked damaged, so I was expecting water or/and oil inside it. I found that the battery had exploded. It is a lithium battery, it leaked and damaged the board.

ECM Sections ⚙️ Do you know the main sections of a Detroit Series 60 ECM? 🤔 🔌 Power Supply, Processing, Injector Drivers, Cab/OEM and 🕵️‍♂️ Sensor processing. 🚚 ⚡️Power management provides power to ECM lower voltage components. 💡The processing side generates injector calculations through the different sensor readings and control signals to different actuators like Fan Control, Engine Brake, VGT. 🌡The sensors side contains temperature, pressure, and timing sensors.
