Reading the ID of a Key
Before you can operate the machine, the MSS must identify a valid electronic key ID. This is done via the exciter coil. Exciter CoilWhen 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 MSS ECM, then the MSS ECM will supply power to the output drivers of the MSS ECM. 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 electronic key near the exciter coil, the MSS ECM will not be able to read the key and
