In alphabetical order
A
AMT: Abbreviation for Automated Manual Transmission Electronic Controlled Unit.
ASC: Abbreviation for Active Stability Control System.
C
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.
D
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.
E
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.
M
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.
93
<<Terminology>>
O
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.
R
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.
S
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.
V
V.C.I.: Abbreviation for Vehicle Communication Interface. The communication interface used to
connect the ECU mounted in the vehicle with a PC.
