Evinrude outboard fault codes (or DTC codes) are diagnostic codes that apply to given malfunctions. These codes can be pulled in many different ways including using diagnostic software or decoding the LED indicators on the EMM.
If you want to find out more about the topic and read the official Evinrude outboard fault codes in one list, this post is for you.
We at PowerSportsGuide have compiled all you need to know under one roof!
What are Fault Codes on an Evinrude Outboard?
Just like many vehicles or heavy machinery, most Evinrude outboards also feature an onboard computer (EMM), which is considered the ‘brain’ of the engine.
In case of a malfunction, this computer generates a code that describes a particular malfunction.
Evinrude outboard fault codes are known by many names including service codes, error codes, and diagnostic trouble codes (DTCs).
How do You Read Fault Codes on an Evinrude Outboard?
In a nutshell, the three easiest ways to read the fault codes on an Evinrude outboard are as follows:
- Decode the EMM LED Indicators
- Use a diagnostic scanner tool
- Take the motor to a service shop
Let’s take a close look at each!
1. Decoding the EMM LED Incidators
As a general rule, each Evinrude outboard is designed with an advanced EMM (Electronic Management Module) that features four indicator lights.
These LED lights are meant to provide a basic reference as to the status of the systems on the outboard.
If your Evinrude outboard has any malfunction, best practice is to check these LED lights as a first step in troubleshooting the issue. Doing this may save you a lot of time and trouble!
The malfunction is often caused by a simple issue like a missing safety lanyard clip or a faulty shut-off switch.
Where can you find these indicator lights on an Evinrude motor?
The first step is to remove the top cowl and locate the EMM (Electronic Management Module) on the top or side of the engine. This unit is a black or sometimes transparent plastic box to which several wire harnesses are connected.
It also features one or two stickers, including the following diagnostic sticker:


The four indicator LEDs are mounted on the top or side of the EMM, right next to this diagnostic sticker to the left.
Note that LED 1 is the closest one toward the top of the EMM, (the closest to the J2 connector).
In other words, you can read the CHARGING OKAY – CHARGING FAULT text right next to the LED 1 light.
Also, beware that the lights have different meanings when the engine is stopped and running.
It’s also good to know that unlike on certain competitor outboard motors, these indicator lights are not intended to provide flashing patterns that refer to given fault codes.
Instead, they can only inform you about the nature of the error.
However, they are a great starting point from which to start your troubleshooting!
If you want to pull the exact fault codes on an Evinrude motor, you will need a diagnostic tool and software.
Evinrude Fault Code Lists
For your convenience, we’ve compiled the official Evinrude fault code lists into this post.
These codes are classed into eight different categories, which are also indicated by the LED lights.
Without further ado, the Evinrude fault code lists are as follows:
Key ON – When the EMM is ON (engine not running), the following LEDs should light:
- LED 1 – SAC Circuit working – 30 V present on 55 V circuit.
- LED 3 – Sensor Circuits working. FLASHING LIGHT indicates Code 57 – engine will not start.
- LED 4 – Stop Circuit not grounded–okay to start. FLASHING LIGHT indicates severe overheat or no oil – engine in SHUTDOWN mode.
I. Evinrude DTCs in Starting Mode
Starting mode occurs from the time the flywheel begins to turn until the outboard is running for 2 seconds. During starting, all four LEDs should light and then go off in sequence.

2. Evinrude Diagnostic Software
If you want to read the error codes that are presently on an Evinrude outboard you will need a diagnostic tool and software. These tools are often referred to as diagnostic scanners.
There are some “universal” outboard diagnostic tools like the CanDooPro, which can be used for many different powersport vehicles from a variety of brands.
But if you are looking for an OEM Evinrude diagnostic tool, it’s the Evinrude Diagnostic Kit & EvDiag diagnostic software.
This kit comes with a special diagnostic interface cable that can connect the brain (EMM) of the outboard to your laptop.
All you need to do is to attach the cable to the outboard’s diagnostic connector to the USB port on your laptop and install the EvDiag software.
This diagnostic tool can be used for various purposes, including:
- Reading and resetting the fault code(s)
- Reading the EMM module identification
- Reading sensors and actuators in real time
- Testing sensors and actuators in real time
- Setting engine operating parameters
- Performing engine maintenance
- Printing engine reports
3. Take Your Motor to a Professional
If you can’t pull the error codes on your Evinrude outboard motor for some reason, your last option is to take it to a service shop.
Although this involves some hassle, a professional can not only read the code for you but can also help with repairs.
How do You Clear the Codes on an Evinrude Outboard?
Once the problem is fixed, the fault codes should clear automatically. However, sometimes they tend to get stuck.
If this happens, you can clear the codes on your Evinrude outboard with a diagnostic tool like an Evinrude Marine Diagnostic Kit or CanDooPro.
Before you clear the codes, make sure that you’ve fixed the triggering malfunction.
Note that fault codes are there for a reason. Never clear them without inspecting and troubleshooting the motor!
It’s also good to know that a history of fault codes and alarms is stored in the ECU for future diagnostics. These codes can’t be cleared.
Takeaways
Evinrude outboard diagnostic codes are also known as fault codes, error codes, or just DTC codes.
These codes refer to given malfunctions that can be decoded by the official Evinrude outboard DTC code list (included above).
Evinrude outboard DTC codes can be pulled in many ways, including decoding the LED indicator lights on the EMM, or using a diagnostic tool.
