Cat® Electronic Key
Illustration 1 g00793955
The Cat® electronic keyThe Cat® key is the universal key for all Caterpillar machines. The electronic key has an electronic chip that is embedded inside the head of the key. The electronic keys are gray or yellow.Exciter Coil
The exciter coil provides communication between the electronic key and the control module.The exciter coil is mounted around the keyswitch. This position allows the exciter coil to communicate with the electronic key. Any ferrous metal between the coil and the electronic key will interfere with the communications. Mounting the coil in the same plane as the top of the keyswitch will minimize the interference.Note: Ensure that you have only one electronic key near the exciter coil when the machine security system (MSS) reads the key. If more than one electronic key near the exciter coil, the MSS ECM will not read the key and the machine will not start.The exciter coil is connected to the harness via a 2-pin connector and a length of wire.Status Indicator
Illustration 2 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. Both LEDs will turn on, producing an orange light if the application software of the MSS has not been programmed into the ECM.Ferrite Coil

Ferrite CoilThe ferrite coil is used to suppress radio frequency emissions. The ferrite coil must be mounted within 400 mm (16 inch) of the ECM. The ferrite coil is used to ensure that the MSS is in compliance with international regulations.
