How to Connect to an ECM with Jaltest

In this Jatlest Marine Software Training article, we will show you how to get connected to an Engine Control Module (EMC) on a marine engine. Depending on the particular Dealer level diagnostic kit you purchased, the Jaltest Marine Software will allow you to connect to either inboard, outboard, inboard & outboard, jetski or stationary diesel engines/generators. All modules are available with the Jaltest Marine Universal Dealer Level Diagnostic Tool.

Using the Search Function

There are a couple of different ways to get connected to the control modules. The first is to use the search function. To use the search function, click on the magnifying glass icon. Here you can search by model or search in the vessel list. To search by model, simply enter your model name, select your engine and click the check box to continue (shown below.) From there you will be able to connect to the ECM.

Manually Connecting

To manually connect to an ECM, select your engine type from the main page. In this example, we will select an outboard engine by clicking the outboard engine icon. This will open the outboard selection window. From here, choose your specific engine type. In our example, we are choosing a Yamaha F60 (shown below.) After completing this step, you will be able to connect to the ECM.

I’ve had the Marine kit since July and I’ve never been able to make connection between the the link and engine even though proper cables are used and configuration correct -I’ve lost numerous jobs because this system doesn’t communicate with most engines ECM diesel or gas – Another wasted $5000.00
