FEATURES
The newly developed Yamaha Diagnostic System provides quicker detection and analysis of engine
malfunctions.
By connecting your computer to the ECM (Electronic Control Module) of a watercraft using the com-
munication cable, this software can be used to display sensor data and data stored in the ECM on a
computer’s monitor.
If this software is run on Microsoft Windows
® 95, Windows 98, Windows Me, Windows 2000, or
Windows XP the information can be displayed in colorful graphics. Also, the software can be oper-
ated using either a mouse or a keyboard.
In addition, the data for the main functions (Diagnosis, Diagnosis record, Engine monitor, and Data
logger) can be saved on a disk or printed out.
Functions
1.Diagnosis:
Each sensor’s status and each ECM diagnosis code or item are displayed. This
enables you to find malfunctioning parts and controls quickly.
2.Diagnosis record:
Sensors that had been activated and ECM diagnostic codes that have been
recorded are displayed. This allows you to check the watercraft’s record of malfunctions.
3.Engine monitor:
Each sensor’s status and the ECM data are displayed. This enables you to
find malfunctioning parts quickly. In addition, the data displayed using the Engine Monitor func-
tion can be displayed in a graph.
4.Stationary test:
Operation tests can be performed with the engine off.
5.Active test:
Operation tests can be performed with the engine running.
6.Data logger:
From the data stored in the ECM, at least two items of 78 seconds of recorded
data are displayed on a graph. In addition, the operating time as compared to the engine speed
and the total operating time are displayed. This allows you to check the operating status of the
engine. For some models, you can also save the ECM record data in a file so that you can read
and display the graph later.
7.Some files:
Lets you select and run other applications while continuing to run the diagnostic
program.
