Cojali Jaltest Expert Mode Explained and Activated

October 26, 2026Jon Logan

If you own one of the Jaltest Marine kits, you need to know about Expert Mode. Expert Mode is a code you enter into the software. Once this is entered you can now perform advanced ECM functions that require programming or writing data to the ECM. This includes DTS calibration, injector coding, engine location, and other functions.

You can setup your Jaltest Marine diagnostic tool one of two ways. The first is to have this code entered one time so that anyone can perform the functions at any time. The other method is using it as security control so that only certain users can perform these advanced functions.

This blog post will cover the details on the first method.

Step 1) From the Main Menu, click on Preferences

Step 2) From the Preferences Menu, select "Configuration"

Step 3) Click on "Activate Expert Mode" on the left side.

You will then need to check the box for accept the Terms & Conditions. After doing this, you can now enter the 6-digit Expert Model code. This will be provided to you by the Marine Diagnostic Tool team. Once completed, click the check mark in the upper right corner to save the data.

Once completed, head back to the main menu and look in the lower left corner. If successful, you will see the word "Expert" shown.

If you are still having issues activating your Marine Expert Mode, please contact our technical support department at 844-627-4630 for further assistance.

FAQ

What does Expert Mode do in Jaltest Marine software?

Expert Mode lets you run advanced ECM functions that require programming or writing data to the ECM. The exact functions depend on the engine, but on supported engines they can include DTS calibration, injector coding and engine location. Without Expert Mode turned on, those write functions stay locked.

Where do I get the Expert Mode code for my Jaltest Marine tool?

The Marine Diagnostic Tools team provides the code. If you run an MDT Marine Gas Pro Kit or MDT Marine Master Kit (both built on Jaltest Marine), contact our team and we will get you set up.

How do I know if Jaltest Expert Mode is activated?

Go back to the main menu after saving and look in the lower left corner. If activation worked, you will see the word "Expert" shown there.

Can I limit Jaltest Expert Mode to certain techs in my shop?

Yes. You can enter the code once so anyone can run the advanced functions at any time, or set it up as a security control so only certain users can. If you want the restricted setup, talk to our team for help configuring it.

Why won't Expert Mode activate on my Jaltest Marine software?

First make sure you checked the box to accept the Terms & Conditions and clicked the check mark in the upper right corner to save. If it still does not show "Expert" on the main menu, call MDT technical support at 844-627-4630.
