Electronic Control Module (ECM) Scanning
We Speak
Your Engine's Language.
Modern marine engines are controlled by complex computers. When the warning alarm sounds, we plug in to reveal the exact fault code, run history, and sensor health.
Factory Access
Generic OBDII scanners do not work on boats. We utilize Rinda and Diacom software—the same tools used by the factory—to communicate with Mercruiser and Volvo Penta ECMs.
Live Data Stream
We don't just read stored codes. We watch the engine run in real-time on our laptops, monitoring fuel trim, manifold pressure, and cooling temperatures to catch intermittent issues.
True Engine Hours
Buying or selling? Analog dashboard gauges can be replaced or broken. The ECM records the actual run time of the engine. We can verify the true hours for you.
The Diagnostic Path.
From vague warning light to pinpoint accuracy.
Connect
We locate the diagnostic port (DLC) on your engine harness and connect our interface module to establish a data link.
Scan & Retrieve
We download the "Freeze Frame" data—a snapshot of exactly what the engine was doing the moment the error occurred.
Actuate Tests
Using the software, we can command the engine to perform tests, such as firing individual injectors or cycling the fuel pump.
Report
You receive a full digital report detailing the fault codes, potential causes, and the verified engine run history.
Smart Repair.
Fixing the sensor, not just the symptom.
Supported Systems.
We service the major marine electronic platforms.
Common Questions
My boat is in "Limp Mode." Why?
This is a safety feature. If the ECM detects a critical fault (like low oil pressure or overheat), it limits RPM to 2000 to prevent catastrophic damage. We scan it to find out why.
Can I use a car scanner?
No. Marine engines utilize different communication protocols (CAN-P, CAN-H, SmartCraft). A standard automotive OBDII scanner will either fail to connect or provide incorrect data.
