General Information
SMCS Code: 7631
The Caterpillar ® Machine Security System (MSS)
discourages unwanted operation of a machine. The
MSS uses the Caterpillar ® Electronic Key or a pass
code entered via a keypad or the machines display.
The keypad or machine display pass code feature is
only available on limited machines. Check the
machines Operation and Maintenance Manual to
verify that this feature is available. The Caterpillar
Electronic Key contains an electronic chip. The
electronic chip has a unique identification number
(ID). An exciter coil is mounted around the key start
switch. The exciter coil reads the ID of the key.
The Electronic Control Module (ECM) of the Machine
Security System is set up with the ID of the keys of
the intended users. When the MSS is armed, the
ECM validates the ID of the key in the key start
switch. If the key ID is in the list of authorized keys in
the ECM and the key is valid, the machine will
operate normally. If the key ID is not in the list of
authorized keys or is not valid in the ECM, the MSS
will keep the critical machine functions disabled.
Components
The Machine Security System consists of the
following components:
• Electronic Control Module (ECM)
• Caterpillar Electronic Key
• Caterpillar Optional key pad entry
• Exciter Coil
• Key Reader Module (MSS3i)
• Status Indicator

The integrated Machine Security System (MSS)
incorporates the MSS software into an ECM. That
ECM controls other machine functions and uses an
electronic key reader (MSS3i) to read the key.
The Electronic Key for the MSS contains an
electronic chip that is embedded in the head of the
key. Each key contains a unique identification
number. The Electronic Key uses the same key cut as
the standard Caterpillar key. The electronic key can
be used to operate any machine that uses the current
Caterpillar key start switch. The Electronic Key
comes in a gray color or a yellow color. The electronic
keys are not configurable.
The exciter coil of the MSS is a ring shaped device.
The exciter coil is mounted around the existing
Caterpillar key start switch. The exciter coil is used
to read the ID that is contained in the Caterpillar
electronic key.
Note: Ensure that you have only one electronic
key near the exciter coil when the MSS reads the
key. If there is more than one key, the ECM will not
be able to read the key and the machine will not
start.

about the MSS to the operator of the machine. The
status indicator has two colors: red and green.
i06195450
System Overview
SMCS Code: 7631
The machine security system (MSS) is designed to
restrict operation of a machine. A list of the authorized
electronic keys for a machine is contained in the ECM
for the MSS. Only a Caterpillar ® Electronic Key that
is authorized can disarm the MSS. This disarming is
accomplished by assigning the ID of an electronic key
to the ECM for the MSS. The Caterpillar ® Electronic
Technician (Cat ® ET) must be used to program the
ECM with the authorized keys.
When the electronic key is placed in the key switch
and turned to the ON position, the key reader reads
the unique ID. This ID is stored in the key. The ECM
will then compare this ID to the list of authorized keys.
6
UENR7000
Systems Operation Section
The status indicator turns a green color when the
MSS has read an authorized key.
• ECM serial number
•
If the ID of the key matches an authorized key, the
status indicator will turn a green color and the MSS
will disarm. This disarming will allow the machine to
operate.
If the ID of the key that is read does not match the list
in the ECM, the status indicator will become a red
color. The MSS remains in the “armed” state and the
machine will remain disabled.
Note: Ensure that you have only one electronic
key near the exciter coil when the MSS reads the
key. If there is more than one key, the ECM will not
be able to read the key and the machine will not
start.
The Machine Security System can be configured to
work in a combination of ways depending on the
electronic architecture of the machine.
1. Electronic Control
The MSS may disable the machine by controlling
the electronic devices that are used to power
critical machine systems.
2. Immobilizer
The MSS disables the machine by communicating
with other electronic control modules across the
Cat Data Link (CDL) and disabling critical machine
functions.
In order to change the list of authorized keys or
change the configuration parameters of the Machine
Security System, the user must:
• Have the Caterpillar Electronic Technician (Cat
ET)
“Product ID” (Serial Number of the machine)
• Serial Number of the Service Tool
• Reason Code
• Total Tattletale number
In order to obtain the proper passwords, the
information must be given to an authorized Caterpillar
dealer.
If a Master Access Level key for a machine being
serviced is not available, a factory password must be
entered before changes can be made. The following
information is needed before you call for a factory
password:
Table 1
Information That is Needed for the Factory Password
Product Identification
Serial Number for the ECM
Serial Number from ET
Tattletale
Reason Code
Note: The password may only be used for one
programming session. A different password will
be required after you exit the Electronic Service
Tool Screen.
i06197898
Normal Operation
SMCS Code: 7631
and one of the following items:
• A key with Master Access Level for that specific
Machine Security System
• A Factory Password
When a key with the master access level is not
available, a Factory Password is required to change
certain parameters in the configuration.
Refer to Testing and Adjusting, “Factory Password Obtain” for additional information on Factory
Passwords.
The Electronic Technician screen for the Factory
Level Security Password will display the following
parameters:
Reading the ID of a Key
Before you can operate the machine, the machine
security system MSS must identify a valid electronic
key ID.
When the key is turned to the ON position, the MSS
enters the read mode. The MSS then checks for a
valid electronic key ID. If the electronic key ID
matches an electronic key ID that is stored in the
ECM, then the critical ECM functions are enabled. An
“enable” message is also sent via the CAT data link
to the other electronic control modules that are on the
machine. The machine will operate normally.
Note: Ensure that you have only one electronic
key near the exciter coil when the MSS reads the
key. If there is more than one key, the ECM will not
be able to read the key and the machine will not
start.
Note: If the ECM has failed or has been removed, the
other critical machine operations controlled by the
other electronic control modules will not operate.
7
UENR7000
Systems Operation Section
Armed
When the MSS is armed, critical machine functions
are disabled. The MSS disables the power that is
supplied to each component that is powered by the
output drivers. The machine will not be able to
operate normally.
There are two states of operation within the “armed”
mode.
1. “ Key Position OFF””
When no power is applied to the MSS, the MSS
will default to “armed” state. When power is
applied to the MSS and the Grace Period has
expired, the MSS will return to the “MSS Armed” .
2. “ Key Position ON””
When the key switch is first moved to the ON
position, the MSS tries to read the electronic key
ID. The ECM will continue reading attempts until
an ID is read or the read time-out expires. If the
key is not read after several attempts, the MSS
turns on the red LED of the status indicator and the
MSS remains armed.
Note: Ensure that you have only one electronic
key near the exciter coil when the MSS reads the
key. If there is more than one key, the ECM will not
be able to read the key and the machine will not
start.
Disarmed
When the MSS is disarmed, the machine can be
operated. The MSS has enabled the starter and main
circuits on the machine. A message is sent to the
other machine ECMs over the Cat data link. The
machine will be able to start. The green LED of the
status indicator will illuminate.
There are two ways to disarm the machine:
• Use a valid electronic key for this machine.
• Use ET to configure the MSS bypass schedule to
allow machine operations during scheduled
periods of time during the week.
Electronic Key
After a machine has been started successfully, the
operator will have 30 seconds after the machine is
turned off before the MSS is automatically armed.
The operator is not required to arm the system
manually.
During the 30 second grace period any key
(electronic and non-electronic) will start the machine
without key identification validation. When the 30
second grace period expires, the MSS will
automatically rearm.
If the MSS is unable to read an electronic key ID, the
system will remain armed.
When the MSS identifies a key with an invalid
electronic key ID, the system will remain armed.
External Authentication Device
(EAD) and Pass Codes
When the machine security system is configured to
utilize External Authentication Device (EAD) and
pass codes, the system will use the default setting.
This setting is an extended 90 second grace period in
addition to the normal grace period of 30 seconds.
The application that configures the library can be set
for a longer or shorter grace period.
Refer to the machines Operation and Maintenance
Manual to confirm use of EAD or pass codes for the
machine.
i06195458
Operation of Status Indicator
SMCS Code: 7631
The Machine Security System (MSS) uses a status
indicator that is mounted in the cab near the key start
switch or in the dash cluster. The status indicator
provides a visible alert of the presence of the security
system. When the key start switch is first turned to the
ON or START positions, and MSS is armed, a red
light status indicator momentarily displays. This light
provides a warning that the machine is armed with a
security system.

Security ID
Access Level
The ID that is stored in the electronic key is a 16-digit
number that is displayed as two 8-digit numbers in
the Caterpillar® Electronic Technician (ET). This field
is known as “Security ID” . When the numbers are
combined, the complete ID number is formed. The
ECM uses this ID to associate a key to the set of
parameters in the list of keys. Entries in the list may
have the same information for the following items:
Description, Access Level and Expiration Date. You
may choose a description of 11 characters or less for
each key in the list of keys. There can be multiple
entries in the list with the same description. Create a
description so that the key describes either the owner
of the key or the function of the user.
You may assign one of two access levels to a key in
the list of keys. The levels are either “Standard” or
“Master” . Both access levels allow the key to disarm
the system for operation. The master access level
also gives the user the ability to modify the settings of
the Machine Security System with the Caterpillar
Electronic Technician (ET).
Passcodes are utilized on some machine in place of
electronic keys. This passcode will be a number
assigned to an operator to allow authorized operation
of the machine. Refer to the machine Operation and
Maintenance Manual for additional information.
The security type identifies the type of security
access that is being utilized. There are currently two
types of security identification.
Note: Duplicate descriptions for the electronic keys
are not advisable.
• Passcode
The standard access level is for normal operation of
the machine. The master access level should be
restricted to those persons that need to modify the
settings of the Machine Security System.

Expiration Date
(Table 4, contd)
An expiration date may be assigned to any key in the
list of keys. This expiration date is defined in 6 hour
intervals on a given date. The third entry in Table 3
contains an expiration date. For all of the other keys
in Table 3 , the column with the expiration date is filled
with “Dash lines” . “Dash lines” indicates that those
entries do not have an expiration date. The Machine
Security System has an internal clock. Once the
internal clock has passed the expiration date for a
key, that key will no longer disarm the system.
However, the entry will not be deleted from the list of
keys. A new expiration date can be set, or the feature
can be disabled. A possible use for the expiration
date is used with a rental contract.
Note: If the machine is running when the expiration
date and time are reached, the machine will continue
to run. When the machine is shut down and the 30
second grace period has timed out, the machine will
not be allowed to restart.

Machine Security System will disarm. The Machine
Security System will return to the “armed” state at
the “Stop Time” . Between these two periods of time,
any Caterpillar ® key will operate the machine. Thus,
the MSS is disarmed during this time period.
All times are based on a 24 hour clock. For example,
6:00 am is 06:00 and 3:00 pm is 15:00. The Machine
Security System will be disarmed during the times
that are listed below: Monday through Thursday from
06:00 to 18:00
SMCS Code: 7631
The Machine Security System can be programmed to
disarm for a time period. The MSS can be set to
disarm for different time periods on each day. Within
these periods of time, any Caterpillar ® key (a
standard key or an electronic key) will operate the
machine.
Note: It is not possible to configure the “ bypass
times”” for an individual electronic key. The
“ bypass times”” are not associated to an
individual electronic key.
“Security System Bypass Times” are time periods
that can be set to disarm the Machine Security
System automatically. An electronic key is not
required during these periods. This feature can be
used for the normal work shift of the machine.
Outside the normal work shift, the Machine Security
System would be armed. When the MSS is armed, an
electronic key is required to start the machine. This
feature would minimize the number of electronic keys
that are needed.
Table 4
On Friday, the MSS is disarmed for only half of the
workday. After 12:00 on Friday, the Machine Security
System will be armed automatically. Operation will be
restricted to operators with electronic keys that are
authorized in the ECM on that machine. Refer to
Table 4 .
The Machine Security System is “armed” on the
weekend. Because the “Start Time” and the “Stop
Time” are set for the same time, the Machine
Security System will be armed throughout the day.
See Testing and Adjusting, “Scheduled Access Program” in order to program the security system
bypass times.

Systems Operation Section
Display the diagnostic code with the Caterpillar
Electronic Technician.
This method of displaying the diagnostic codes uses
the service tool to display the codes. The Component
Identifier (CID) identifies the specific component for a
specific diagnostic. The Failure Mode Identifier (FMI)
identifies the type of diagnostic that was detected.
The diagnostic codes allow consistent identification of
the problem. The service tool is used to display the
CID-FMI with descriptive text for each combination.
The descriptive text will help to avoid mistakes in
interpreting the codes.
Active Diagnostics
Active diagnostics indicate the presence of active
diagnostic codes for the MSS. A diagnostic code
informs the operator that a problem exists with the
MSS.
If the Cat service tool is available, the service tool
can be used to display all active diagnostic codes.
The service tool will also display codes that have
been logged.
i06195511
Protected Functions
SMCS Code: 7631
There are two levels of protection for the machine
security system (MSS) :
• An electronic key with standard access level and a
non-electronic key
• An electronic key with master access level (factory
password)
The requirements for each level are explained below:
An Electronic Key with Standard Access Level
and a Non-electronic Key
• The table of the MSS keys can be viewed but the
table cannot be modified.
• The configuration settings of the MSS can be
viewed but the settings cannot be modified.
Logged Diagnostics
Electronic Key with Master Access Level
A logged diagnostic will record problems that are
intermittent for the Machine Security System. Logged
diagnostics eliminate the need to duplicate problems
that are intermittent. Logged diagnostics will increase
the accuracy of diagnosis. The time that is required to
troubleshoot a problem is reduced with the use of
Diagnostics. Logged diagnostics eliminate the need
for trip recorders that are used to capture intermittent
diagnostic information.
A factory password or a master access level is
needed to modify any MSS settings through the
service tool.
The control module memory is used to store
diagnostic information. When a diagnostic is
detected, the following information is logged:
Service Operation Using
Service Tool
• The CID will identify the component that has failed.
SMCS Code: 0785-UE; 7631
• The FMI will describe the problem.
The service tool is used to communicate with the
ECM for the following information:
• Number of occurrences of the diagnostic code
• The time of the first occurrence that the diagnostic
was detected.
• The settings for the MSS can be modified.
• The list of valid key IDs can be modified.
i06195540
• display and control of code
• programming
• Last occurrence time, when the diagnostic was last
detected (stored with both machine hours and
RTC stamp)
• management
The problems which can be logged are listed in
Troubleshooting, “Diagnostic Code List”. Refer to the
Troubleshooting manual for your machine
To protect the machine properly, the service tool
requires a factory password or master access level
key, before modifications can be made to the MSS.
The ECM logs the number of times that the machine
is started with the methods that are listed below:
• Starting using an unauthorized method
• diagnostics

as the top of the key start switch will minimize the
interference.
Note: Ensure that you have only one electronic
key near the exciter coil when the MSS reads the
key. If there is more than one key, the ECM will not
be able to read the key and the machine will not

g00862013
The state of the MSS is displayed by the status
indicator. The green LED of the status indicator turns
ON when the system is disarmed. The machine
should start. The red LED of the status indicator turns
ON when the system is armed and an invalid
electronic key has been read by the MSS. The
machine should not start. The green LED and the red
LED will remain OFF when the machine security
system is not installed.

g01007352
When the key start switch is placed in the ON
position, the ECM will send a signal over the CAN
data link. That signal will command the key reader to
excite the coil. The key ID from an electronic key is
sent back to the requesting ECM over the CAN data
link.
Note: The key reader is NOT designed to
communicate with the Caterpillar ® Electronic
Technician (Cat ® ET). However the key reader
control can be flashed via Cat ® ET. Refer to Test and
adjust section, “ECM Flash” section of this manual.
Note: The Status indicator may be located in the
dash cluster on some machine. Refer to the System

CAT Data Link
The Cat Data Link can connect the ECM for the
following items:
• Service tools
• Onboard controls
• Monitoring systems
The service tool can send information to the ECM
through the Cat Data Link. The ECM can provide
information over the Cat Data Link to the following
items: other electronic controls and service tool. The
information can be for diagnostics, or the information
can be used to control other systems on the machine.

Systems Operation Section
CAN Data Link
The CAN Data Link is an input and an output of the
machine ECM. The CAN Data Link is designed to
communicate with other electronic control modules
through the machine harness. The CAN Data Link
consists of internal ECM circuits and a twisted pair of
wires within the wire harness. The CAN Data Link is
bidirectional. The CAN Data Link allows the ECM to
receive and transmit information and the CAN Data
Link allows the ECM to send and receive information.
The CAN Data Link communicates at a faster rate
than the CAT Data Link.
The Electronic Key Reader (MSS3i) utilizes CAN data
link for flashing.

General Information
SMCS Code: 7631
Caterpillar Electronic Key
The machine security system (MSS) uses a
Caterpillar Electronic key. The key contains an
electronic chip that is embedded in the head of the
key. This chip contains a unique identification
number. No two keys have the same ID. The
Electronic Key uses the same key cut as the standard
Caterpillar key. The electronic key can be used to
operate machines that are not equipped with the
MSS. The head of the electronic key is gray or yellow
in color.
A System Disarm Feature will allow a machine to
operate with any key. Refer to the Testing and
Adjusting, “Scheduled Access - Program” for
additional information.
Security Management
The Machine Security System uses the Caterpillar
Electronic Technician (ET), version 2015A or later, to
manage the settings of the system. There are
restrictions on accessing the settings. The “Security
Management” feature for the MSS controls the
access to the settings.

Glossary of Terms
SMCS Code: 7631
Armed – The state of the security system when the
machine is disabled.
CAN Data Link (CAN) – The CAN data link is an
electrical connection for communication with onboard
devices.
Disarmed – The state of the security system when
the machine is able to operate normally.
Electronic Control Module – The portion of the MSS
that contains the microprocessor and memory
Electronic Key Reader – The electronic key reader
module sends key information to the ECM. The
information is transmitted from the exciter coil to the
key reader module.
EID – Event Identifier
Exciter Coil – The exciter coil is a small coil of fine
wire. The wire is molded into the bezel of a keyswitch
with harness wiring. The exciter coil provides a path
of communication. The electronic key and the
electronic control module communicate via radio
frequency.
Factory Password – Protects the machine when
using the service tool. The password must be used
when any modifications are done to the MSS.
Immobilizer – The Machine Security System
Immobilizer is a feature within another ECM (Engine
and/or Transmission). This feature restricts the
operation of the machine until the Machine Security
System disarms.
Master Access Level – A level of access to permit
the operation of the machine. In addition, the key
allows the user to add new keys into the ECM and
allows MSS settings to be modified without a factory
password. Also, keys that are already programmed
can be modified.
MSS – Machine Security System
PID – A parameter identifier is used to identify
specific parameters that are used by the MSS.
Product ID – The Product ID is an 8 digit
alphanumeric number that identifies the machine.
Programming – Programming refers to the process
of storing information in the memory of the control
module.
Software Enable Attachment – A feature or function
on a machine that uses software in order to enable
the functionality. The actual software used to
accomplish the function is embedded in the standard
machine software (flash file). The feature requires a
factory level password in order to activate.
Standard Access Level – Keys that are
programmed for this level of access permit the
operation of the machine.
Tattletale – The tattletale is a counter in the ECM that
is used as part of the calculation for the factory
password. The tattletale is incremented after a factory
password is used. The affected parameter will have
an increase in the specific parameter of the tattletale
and the total tattletale will reflect the increase as well.
Once you use the factory password, the factory
password will no longer be valid. To make a change
on the same ECM at a later date, another password
will be required.
