Yamaha WaveRunner Fault Code List [Chart]

Even if you properly maintain your WaveRunner, problems can still occur. Malfunctions are always a big hassle, especially if you are on an offshore ride!

If your WaveRunner won’t start or has other issues, you can try to troubleshoot the problem yourself.

But if you can’t solve the problem, you will have to read the fault codes to learn more about the fault.

For your convenience, we at JetDrift have compiled the official Yamaha WaveRunner fault codes into this post, which also explains how to read them!

How to Read Yamaha WaveRunner Fault Codes

You can read the Yamaha WaveRunner fault codes with a Marine Engine Diagnostic System (MEDS) or CandooPro, which are special softwares designed for troubleshooting WaveRunners and other marine engines. You just have to connect the computer to the engine with the diagnostic cable that comes with the software. If you don’t want to invest in this software, you will have to take your WaveRunner to a dealership or service shop to read the fault codes.

There are many advantages of this MEDS marine diagnostic software, such as:– Compatible with different PWC models

– Compatible with several marine engines like Yamaha, Mercury, Suzuki, Tohatsu, Honda

– Diagnostic cables are included in the package

– It runs engine tests while it collects and registers data to diagnose problems.

– It can help you to determine the fault faster and much more efficiently.

– Has an easy-to-read, user-friendly interface.

One of the best features of MEDS is the History tab, where you can find all records and faults that have occurred in the past. This history can be saved into a file and erased if needed.

You can find the current faults with details on the ‘Active Faults Tab.’

Conclusion

You can read fault codes on a WaveRunner with special diagnostic software. The two most commonly used softwares are the MEDS (Marine Engine Diagnostic Software) and the CandooPro.

You have to install them on your computer and connect it to the WaveRunner with a diagnostic cable, which is included in the package.

It’s an easy and convenient way for you to read the fault codes on your WaverRuuner yourself.

Drawbacks?

Unfortunately, these softwares are quite expensive. As an example, CandooPro Home/Limited Edition costs around $400.

If you don’t want to invest in one of these diagnostic softwares, your other option is to take your WaveRunner to a dealership.

Let’s face it, this is often the best option, because even if you can read the fault code at home, you will probably have to take the craft to a mechanic for repairs.
