ENGINE TROUBLE DIAGNOSTICS TOOL AND MAINTENANCE TOOL
1. Introduction
Our maintenance tools are designed to identify the causes of troubles so that machines can be quickly returned to
normal. We also offer a tool to adjust the quantity of oil in the service port for machines with an optional attachment,
to ensure safer maintenance work. These tools are offered only to the designated dealers, and are to be used by main-
tenance technicians with knowledge of computers, so the basic computer operations are not explained.

2. System overview

There are two main tools for maintenance: the engine trouble diagnostic tool provided by the engine manufacturer and
the maintenance tool provided by Takeuchi. Some of our machines have a control computer which can be connected
to a personal computer for communications, allowing computers to read or write data.
(1) Engine trouble diagnostic tool
This tool is used to diagnose troubles with the engine controller of machines with Tier 3-compliant engines and to
flash the engine control data. It can be purchased from the engine manufacturer, Isuzu or Yanmar. Tier 3-compliant
engines are electronically controlled by the Engine Control Unit (ECU) or Engine Control Module (ECM). These
controllers use data specific to Tier 3-compliant and regulation-approved engines, and the trouble diagnostic tool
is specifically designed for them; regular maintenance software for the controller intended for the whole machine
cannot be used.
In case of trouble, the engine trouble diagnostic tool is used to display the error codes and states, from which the
cause of trouble can be identified and action taken according to the engine manufacturerʼs manual.
To purchase the tool, contact our Sales or Parts department.
For details of the tool, read the userʼs manual of the manufacturer.
The maintenance software is permitted to be used only by licensed manufacturers and service dealers.
(2) Maintenance tool and maintenance software
This tool is used to read data from the machine controller and to adjust peripheral devices.
• Reading the error codes stored in the Takeuchi Electrical Control Unit (T-ECU)
Past trouble details can be read or deleted.
∗ For the details of error codes, refer to the manual included in the software CD and the maintenance manual.
• Reading the parameters and writing the modified data in the proportional amplifier for the service port
The proportional output for the first/second auxiliary line can be modified.
The operation speed of various attachments can be modified.
• It is possible to read each serial number and the software version of the controller connected to the device.
The serial number of the controller is necessary for manufacturing management or for troubleshooting.
