System Checks will need to be done with the engine running. 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. 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. Just like TEXA, Jaltest offers real time graphs for various measurements. The measurements tab shows various data such as engine speed, key switch battery potential, sensor supply voltage and more.

Again, this will come in handy when determining if an engine has been abused by running at a high RPM for too long.Īccessing the Parameters tab will give you the option to either display or modify parameters. Much like the Engine History tab for TEXA, the Engine Hours section in Jaltest displays the operation time for a variety of RPM ranges. From here you will see your engine location and calibration identification.

To access ECU Data, select Diagnostics Menu>System Data>ECU Data. You can access system data by selecting System Data from the Diagnostics Menu on the left. 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.

Just as we saw with the TEXA software in our last blog post, the Jaltest software also returned no fault codes. In our example, we are using the JDC 650 + JDC 617M. It shows the cables used to diagnose the engine. Once connected, this is the first screen that pulls up. We connected to this engine with the JDC 650 + JDC 617M to the terminator selecting the ECM (CAN) selection. In this article, we will be using Jaltest. (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 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.
