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.
Diagnostic tool databases are updated three times per year for major platforms like Jaltest, but new engine models released by manufacturers can take a few months to years to appear in production diagnostic software. This lag is unavoidable and reflects the time required to discover, validate, and test new engine configurations.
If you've been using diagnostic tools for a while, you might have experienced the frustration of trying to explain a technical problem over the phone. "It shows a red box on the left side... no, the other left... Now it's green." When you switch to remote support, the technician can see exactly what you're seeing. Let's walk through how a typical remote support session works with Marine Diagnostic Tools, and why it's so much more effective than trying to solve problems over the phone.
Most technicians don't need more data, they need clarity. A good diagnostic tool should let you work across multiple engine brands, diagnose both gas and diesel, run tests and calibrations, access wiring diagrams and troubleshooting steps, and solve problems without switching tools or guessing. If your tool can't do that, it becomes a bottleneck.
Every technician using an independent diagnostic tool eventually encounters this frustration: you buy a new software package, connect to a brand-new engine, and discover coverage is incomplete. The tool feels like it's holding back. In most cases, it's not holding back, coverage simply hasn't been developed yet. This lag happens to every independent platform, regardless of brand.
Choosing a marine diagnostic tool is one of the most important decisions you'll make as a boat owner, technician, or shop manager. Unlike generic automotive scanners, marine diagnostics require understanding the unique systems found on boats. From outboards and inboards to diesel engines, electrical systems, and integrated marine electronics, your tool must handle complexity across multiple domains. The right tool saves you money, time, and frustration. The wrong one becomes an expensive paperweight that collects dust in your shop.
