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.

Scheduled Access
( “Security System Bypass
Times” )
SMCS Code: 7631
The Machine Security System can be programmed to
disarm temporarily 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 shows an example of “Security System
Bypass” . The “Start Time” is the time when the
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
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 MSS3s 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.

Diagnostic Operation
SMCS Code: 7631
A diagnostic code indicates that the ECM has
detected one or more of the following conditions:
• an invalid signal from an input
• an improper feedback from an output
• an internal error
One method of displaying diagnostic information is
provided:
• Diagnostic codes with descriptive text can be
viewed with the Caterpillar Electronic Technician
(ET).
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.
