Yamaha Diagnostic System
Introduction
Features
The newly developed Yamaha Diagnostic System provides quicker detection and analysis of engine
malfunctions for quicker troubleshooting procedures than traditional methods.
By connecting your computer to the ECM (Electronic Control Module) of an outboard motor using
the communication 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
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: With the engine main switch ON, each sensor's status and each ECM diagnosis
code or item is 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 outboard motor's record of malfunctions.
3. Engine monitor: Each sensor status and the ECM data are displayed while the engine is run-
ning. This enables you to find malfunctioning parts quickly.
4. Stationary test: With the engine off, the ignition, fuel injection, electric fuel pump, and ISC
valve are checked. These tests can be performed quickly.
5. Active test: With the engine running, each firing cylinder has dropped and the engine speed is
checked for changes to determine whether the cylinder is malfunctioning and the ISC valve is
checked as well. These tests can be performed quickly.
6. Data logger: Displays 13 minutes of recorded data for two or more of the items stored in the
ECM. 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.
7. Some files: Lets you select and run other applications while continuing to run the diagnostic
program.
