Machine Security System (If Equipped)
NOTICE
This machine is equipped with a Caterpillar Machine
Security System (MSS) and may not start under certain
conditions. Read the following information and know
your machine's settings. Your Caterpillar dealer can
identify your machine settings.
Machine Security System (MSS) - Machines
that are equipped with a Caterpillar Machine
Security System (MSS) can be identified by a
decal in the operator station. MSS is designed to
prevent theft of the machine or unauthorized operation.
Basic Operation
MSS may be programmed to read a standard
Caterpillar key or an electronic key. The electronic key
contains an electronic chip within the plastic housing
for the key. Each key emits a unique signal to the
MSS. The keys can be identified by a gray housing or
a yellow housing. MSS can have programmed settings
to require an electronic key or a standard Caterpillar key
for starting during certain periods of time.
When the key start switch of the machine is turned to
the ON position, the ECM will read the unique ID that is
stored in the electronic key. The ECM will then
compare this ID to the list of authorized keys. The
following table tells the operator the status for starting
the machine. The status light is located near the key
start switch.
Table 9
Note: MSS will not shut down the machine after the
machine has started.
Security Management
The MSS has the capability to allow you to program the
system to automatically activate at different time
periods with different keys. The MSS can also be
programmed to reject a specific electronic key after a
selected date and time. When you turn the key to the
OFF position and the MSS is active, you have a 30
second interval in order to restart the machine with an
unauthorized key. Also if the machine stalls, there is a 30
second interval for restarting the machine. This 30
second interval is counted from the time of turning the
key to the OFF position.
Note: Know your machine's settings because the use of
an electronic key is no guarantee that the machine can
be restarted.
An expiration date can be set for each electronic key
that is contained in the list of keys for the machine. The
key will no longer start the machine when the internal
clock in the security system passes the expiration
date. Each entry in the list of keys can have a different
expiration date.
Spare keys are available from your dealer. Before a key
can operate the machine, the MSS must be set to
accept that particular key. Consult your Caterpillar
dealer for information on additional features of the
MSS.
Battery Disconnect Switch (If Equipped)
Open the engine enclosure on the right side of the
machine. The battery disconnect switch is located on
