Operation Section
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. THE MSS is designed to be a theft deterrent or the MSS will prevent the unauthorized operation of the machine. Basic Operation
MSS may be programmed to use 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 may have programmed settings that require an electronic key for starting during certain periods of time. The MSS may also have programmed settings that allow a standard Caterpillar key to start the machine during certain periods of time.Note: Ensure that you have only one electronic key near the exciter coil when you are attempting to start the machine. If there is more than one electronic key near the exciter coil the MSS may not be able to read the key in the keyswitch and the machine will not start.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.
