Fitment & setup
Does it display live sensor data?
No. Innova specifies that the 3145 does not read live data. Use it as a code reader for a confirmed supported system.
Will it work with my GT40 engine computer?
Send your engine and computer identification plus a clear test-connector photo. Marine compatibility needs an exact match check; automotive applications are not a marine fitment guide.
How should I use a retrieved code?
Use the code with the service procedure for your exact engine and computer. Diagnose the indicated condition before selecting replacement parts.
