Functions of the Lamps
Shutdown Lamp
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless there is an active warning.Flashing - The lamp will be flashing when a derate is active or when a derate is present because of an active diagnostic code. An example of an active diagnostic code is "System Voltage High".On - The lamp will be on when the shutdown level in the engine protection strategy has been reached. The "Warning" lamp will also be on.Warning Lamp
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless there is an active warning.Flashing - The lamp will be flashing when a "warning" or a "warning and derate" is active. This includes low oil pressure.On - The lamp will be on when the shutdown level has been reached. The "Shutdown" lamp will also be on.Wait to Start Lamp
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless "Wait to Start" is active.On - The lamp is on during a "Wait to Start" period.Low Oil Pressure
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless there is an active warning.On - The lamp will come on when a low oil pressure event is detected. The "Warning" lamp and the "Shutdown" lamp may also come on.PTO Lamp
Lamp check - The lamp will come on for 2 seconds. The lamp will then go off unless the PTO mode is active.Flashing - When the keyswitch is turned to ON, the lamp will be flashing when the PTO mode is turned on but when the PTO is not engaged.On - The lamp will come on when PTO mode is engaged.Color of Lamps
Typically, the "Shutdown" lamp is colored red and the "Warning" lamp is colored amber. The other lamps are optional.Operation of the Indicator Lamps

Warning Lamp
(Alert Lamp)     Shutdown Lamp
(Action Lamp)     Lamp State     Description of the Indication     Engine State    
On     On     Lamp Check     When the keyswitch is moved to the ON position, the lamps come on for a period of 2 seconds and the lamps will then go off.     The keyswitch is in the ON position but the engine has not yet been cranked.    
Off     Off     No Faults     With the engine in operation, there are no active warnings, diagnostic codes or event codes.     The engine is operating with no detected faults.    
On     Off     Active Diagnostic     If the warning lamp comes on during engine operation, this indicates that an active diagnostic code (an electrical fault) is present.     The engine is operating normally but there is one or more faults with the electronic management system for the engine.    
On     Flashing     Derate
(A derate is caused by certain active codes.)     If the warning lamp comes on and the shutdown lamp flashes during engine operation, this indicates that an active diagnostic code (an electrical fault) is present. The diagnostic is sufficiently serious in order to cause an engine derate.     The engine is operating but there is one or more active diagnostic codes that have initiated an engine derate.    
Flashing     Off     Warning
(Warning only)     When the warning lamp flashes during operation of the engine, the lamp indicates that one or more of the warning values for the engine protection strategy has been exceeded. However, the value has not been exceeded to a level that will cause a derate or a shutdown.     The engine is operating normally. However, there is one or more of the monitored engine parameters that are outside of the range that is acceptable.    
Flashing     Flashing     Derate
(Warning and Derate)     If both the warning lamp and shutdown lamp flash during operation of the engine, the lamps indicate that one or more of the values for the engine protection strategy have been exceeded beyond the level that will cause an engine derate.     The engine is operating. However, one or more of the monitored engine parameters is outside of the acceptable range. The acceptable range has been exceeded to a level which requires a warning and an engine derate.    
On     On     Engine Shutdown     If both the warning lamp and the shutdown lamp come on during engine operation, this indicates one of the following conditions.
1. One or more of the shutdown values for the engine protection strategy has been exceeded.
2. A serious active diagnostic code has been detected.
After a short period of time, the engine will shut down.     The engine is either shutdown or an engine shutdown is imminent. One or more monitored engine parameters have exceeded the limit for an engine shutdown. This pattern of lamps can be caused by the detection of a serious active diagnostic code.    Flash Codes
The "Flash Code" feature is used to flash the code of all active diagnostic codes and logged diagnostic codes.The sequence for the flash code is started by moving the keyswitch to "Off" and then moving the keyswitch to "On" twice within a period of three seconds. After a delay of 2 seconds, the "Shutdown" lamp will flash once for a period of half a second. This sequence indicates the start of the active fault codes. After a further delay of 2 seconds, the "Warning" lamp will flash repeatedly in order to indicate the active diagnostic codes. Each flash will be on for half a second and off for 300 milliseconds. The "Warning" lamp will remain off for 2 seconds between each digit of a code. If there is more than one active diagnostic code, the "Shutdown" lamp will go off for 2 seconds. The lamp will then come on for a period of half
