When you retrieve DTCs from your engine, it’s important to understand what they mean. Most scan tools will include a code library or you can consult a Mercruiser repair manual or online resource to find a detailed description of the code.
Troubleshooting Engine Problems
Once you have identified the DTCs, you can start troubleshooting the engine problem. The scan tool can guide you to the specific component that needs attention. For example, if a code indicates a problem with the fuel pressure sensor, you can use the scan tool’s live data feature to monitor fuel pressure while the engine is running.
Performing Actuator Tests
The actuator test feature allows you to verify the functionality of various engine components. For example, you can use this feature to test the fuel pump, ignition system, or throttle position sensor.
