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 laptop 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 laptop computer’s monitor.
If this software is run on Microsoft Windows

®

95, Windows 98, Windows Me, or Windows 2000 the

information can be displayed in colorful graphics. Also, the software can be operated 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 start switch set to ON, each sensor’s status and each ECM diagno-

sis 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, electric oil

pump, electric fuel feed pump, and ISC valve are checked. These tests can be performed
quickly.

5.

Active test:

With the engine running the ISC valve is checked as well. These tests can be per-

formed quickly.

6.

Data logger:

From the data stored in the ECM, at least two items of 13 minutes 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.

7.

ECM No.:

The ECM part number is displayed.
