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 the engine is derated 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 situation includes low oil pressure.On - The lamp will be on when the shutdown level has been reached. The "Shutdown" lamp will also be on.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.Color of Lamps
Typically, the "Shutdown" lamp is colored red and the "Warning" lamp is colored amber. The color of the other lamps can vary.Operation of the Indicator Lamps
Table 1
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 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, the lamp 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
(An engine derate is caused by certain active codes.) If the warning lamp comes on and the shutdown lamp flashes during engine operation, 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, 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 the engine to 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) The warning and shutdown lamps flash if a value for the engine protection strategy has exceeded the level for 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, one of the following conditions exists:
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 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.As an example, an active diagnostic code of "21" is indicated by the "Warning" lamp operating in the following sequence:
On for 500 ms
Off for 300 ms
On for 500 ms
Off for 2000 ms
On for 500 ms
Off

Timing of the flash codes
After all of the active diagnostic codes have been displayed, the "Shutdown" lamp will go off for 2 seconds. The "Shutdown" lamp will flash twice in order to indicate the start of the sequence that will display the logged diagnostic codes. The process for flashing logged diagnostic codes is identical to the process for flashing active diagnostic codes.Note: If there are no logged codes, the "551" code should be flashed again.After all of the codes have been displayed, the "Shutdown" lamp will flash three times in order to indicate that there are no further codes. Cycling the keyswitch twice within a period of 3 seconds will start the process again. All codes will be displayed in ascending numerical order.Refer to the Troubleshooting Guide, "Diagnostic Code Cross Reference" for the diagnostic code that relates to the flash code.Note: Flash codes are always sent in ascending numerical order.
