1999 Mercury (Ser. 0G886121):
I'm getting ready to use the Rinda Diacom software to scan my motor because of a check engine light that will not go out. Was wondering if some of you all familiar with this system could answer a couple of questions. Do you run the scan with the ignition on (motor not running), with the motor running, or both? I'm a little confused because the manual says to "turn the ignition on", but I wasn't sure if that meant to actually start up the motor. Some of the manual diagrams I see appear to show parameters at an elevated value, which would mean the outboard is running, and I couldn't really find anything on YouTube showing someone using the system.
Also, looking at the different system test you can activate, such as with the ignition, fuel injectors, etc..., I assume when you do these with the ignition on (motor not running)???
