( 1 ) This mode can be accessed while the machine is operating.There are twelve service modes to aid in troubleshooting, calibration and adjusting machine performance. The service modes allow the technician to do most troubleshooting without disconnecting connectors or modules. Some of the modes can only be accessed with the engine off while other modes allow the operator to drive the machine and monitor its performance as it occurs.Each service mode is assigned a mode number. The service modes of the EMC are listed in the Service Modes chart. This mode number is entered into the EMC by using the keypad. After the mode number is entered, the corresponding service operation begins. See the following topic: Entering And Exiting A Service Mode.
