Data List Item Name
(Explanation for the meaning of underline)
-There are items among data list whose name are
underlined. The underlines of these items mean that
support for these items depends on configuration of
vehicle equipment. When a vehicle has a particular
part and related data list item is supported, you can
check its value on M.U.T.-III.
- However, when the data list item is underlined, there
are also vehicles that do NOT have this part. In this
case, even if the data list item is displayed on
M.U.T.-III, it is not supported and value will not
change.
- So please consider the above when dealing with
similar data list items during vehicle inspection and
service work.
Note:
- For example, there is a data list item “Driver’s
seatbelt switch” in a M.U.T.-III screen shot below.
This item is underlined and means that some
vehicles do not have related switch and value will not
change. In this case you need to check if the vehicle
is equipped with the switch before proceeding with
trouble shooting.

In alphabetical order
iAi
AMT: Abbreviation for Automated Manual Transmission Electronic Controlled Unit.
ASC: Abbreviation for Active Skid Control System.
iCi
CAN: Abbreviation for Controller Area Network. A system that shares data between ECUs through
communication. The processing of each command (signal) is possible using a communication line
only.
iDi
Data transmission: The transmission of data stored from one memory area to another memory
area. In the case of M.U.T.-III, this refers to the transmission of data from the V.C.I. memory area
to the PC.
Default: Initial setting. A predetermined value that is set when an item that should be defined is not
defined.
Diagnosis: Refers to the self-diagnosis function. A system in which the ECU installed in the
vehicle monitors input signals from the various sensors and switches and, when an error occurs or
erroneous information is identified, records the data in memory.
iEi
ECU: Abbreviation for Electronic Control Unit. The control unit of the electronic control system.
EPS: Abbreviation for Electric Power Steering
iIi
I/F cartridge: A cartridge used when the ECU communication method employed is a special
method or when M.U.T.-III functions have been expanded and support is not possible by the
M.U.T.-III unit alone. The various I/F cartridges, such as the cartridge for the SWS monitor set in
M.U.T.-II or the cartridge for DCC communication, can be used as is.
iMi
Memory card: A medium used to store data. Records data such as those used for ECU updates.
With M.U.T.-III, flash memory is employed which allows the user to electrically change the data as
well as maintain the information even if the power is turned off. Batteries are not required.
135
<<Terminology>>
iOi
Online help: Also referred to as the online manual. An operation manual loaded on M.U.T.-III,
which gives easy-to-understand explanations on how to use the various functions.
It also
provides processing methods related to the operation currently performed when the user is unsure
how to perform an operation during application use.
iRi
RAM: Abbreviation for Random Access Memory. A memory device that is capable of both read
and write operations. The information stored in this device is lost when the power is turned off.
ROM: Abbreviation for Read Only Memory. A memory device that is capable of read operations
only. The information stored in this device is maintained even when the power is turned off.
iSi
Serial communication: A method in which the bits that make up digital data are transmitted in
series one bit at a time on the communication line. The reading of diagnostic code via
communication from the ECU using the M.U.T. is referred to as “Pattern Diagnosis.”
Slide bar: A method in which a value is entered by moving a bar.
SWS: Abbreviation for Smart Wiring System. A system that centrally controls multiple electrical
signals on one harness, thereby minimizing the number of harnesses used. The SWS lead to the
development of the multiplex transmission system, making harness weight reduction and the
development of multifunctional electrical components possible.
iVi
V.C.I.: Abbreviation for Vehicle Communication Interface. The communication interface used to
connect the ECU mounted in the vehicle with a PC.
