Can Diagnostic Tools Reset Maintenance and Fault Codes?
June 1, 2026
Some modern engines use 'pending codes,' which are codes that have triggered once but aren't yet stored permanently. If the same condition doesn't recur within the next 10 to 20 engine starts, the pending code expires and clears automatically. Confirmed codes, by contrast, are stored codes that persist indefinitely until manually cleared.

Maybe you bought the tool two years ago, and now you're facing a newer engine variant that isn't in your database. This is where software updates become absolutely critical. But how do updates actually happen? When should you expect them? What new coverage will they bring?

April 20, 2026
As a boat owner, you might think diagnostics are only for professionals. But modern boats generate fault codes just like modern cars. When your engine displays a warning light, starts running rough, or loses performance, a diagnostic tool reads the underlying problem. Without it, you're guessing.
