Diagnostics on a 2014 Mercury (Part four - Diacom)

Diagnostics on a 2014 Mercury (Part four - Diacom)

In this comparison blog series, we are exploring the differences between running diagnostics with software from TEXAJaltestMEDs and Diacom on a 2014 Mercury 60 HP outboard engine. (Please note that Marine Diagnostic Tools does not sell Diacom products. Diacom was used for testing and comparison only.) In part one, we reviewed using TEXA software for diagnostics. In part two, we reviewed the Jaltest software. In part three, we reviewed the MEDS unit. In this article, we will be taking a look at using Diacom software to diagnose our 2014 Mercury 60HP outboard engine.

We began our Diacom experience by locating the Terminator plug (shown below.) Next, we connected the 94073 + 94032 + 94029 to the Terminator plug (shown in the second image below.)

First Page

After connecting to the engine and opening the software the first page displayed has a Diacom image over the interface. The application is much like MEDS in that uses both a horizontal top navigation system made of tabs combined with a vertical column of menus. The main difference here is that the vertical column was on the left this time rather than the right, like MEDS.

Cable Selection

The Cable Selection screen was one of the nicer features of the program interface, with plenty of high quality cable photos to ensure the correct cable.

Fault Codes

Just as we saw with TEXA, Jaltest, and MEDS, the Diacom software found no active fault codes.

Parameters

For the first time in our review series we were unable to get any parameters to pull up using the software. This could have been due to the Diacom software hanging up and lagging during testing. Perhaps with more time and troubleshooting of the software this may have worked, but unfortunately our tests were inconclusive.

Activations

Below are several tests that could be performed using this software and tool.

Summary

The Diacom software had excellent cable images and was easy to use. It was also capable of running the same tests as we ran with TEXA, Jaltest, and MEDS. However it was the most limited in functionality as no parameters could be pulled up during our testing.
