Diagnostics on a 2014 Mercury (Part two - Jaltest)
In this comparison blog series, we are exploring the differences between running diagnostics with software from TEXA, Jaltest, MEDs 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 this article, we will be using Jaltest.
We connected to this engine with the JDC 650 + JDC 617M to the terminator selecting the ECM (CAN) selection.
Cable Selection
Once connected, this is the first screen that pulls up. It shows the cables used to diagnose the engine. In our example, we are using the JDC 650 + JDC 617M.
Fault Codes
Just as we saw with the TEXA software in our last blog post, the Jaltest software also returned no fault codes.
System Data
Here you will notice that unlike TEXA's Software which relies on a series of horizontal tabs for menu items, Jaltest opts for a vertical column layout. You can access system data by selecting System Data from the Diagnostics Menu on the left.
ECU Data
To access ECU Data, select Diagnostics Menu>System Data>ECU Data. From here you will see your engine location and calibration identification.
Engine Hours
Much like the Engine History tab for TEXA, the Engine Hours section in Jaltest displays the operation time for a variety of RPM ranges. Again, this will come in handy when determining if an engine has been abused by running at a high RPM for too long.
Parameters
Accessing the Parameters tab will give you the option to either display or modify parameters.
Measurements
The measurements tab shows various data such as engine speed, key switch battery potential, sensor supply voltage and more.
Measurements Graphing
Just like TEXA, Jaltest offers real time graphs for various measurements.
Activations
On our Mercury 60HP Engine, Jaltest allows you to actuate the following components: the warning buzzer, ignition coils, tachometer, injectors, fuel pump relay and idle air controller.
Coil Test
Injector Test
IAC Valve
You can select the graph icon by the arrow to see this activation graphed while the test is running, or the software will ask you when the test is complete to see a graph.
System Checks
System Checks will need to be done with the engine running.

Troubleshooting
The Jaltest software ran great on this engine, the wiring diagrams were missing from this selection and the other information was from another model however, we did not have any problems it all ran well on this engine.
