Instrument Panel - Elect. Cont. Later Engines Instrument Panel (Continued) When the engine starts, the key is released and returns to the (RUN) position. A—Diagnostic Gauge/Hour Meter G—Override Shutdown Rocker Switch The diagnostic gauge (A) displays diagnostic trouble codes (DTCs) as they are accessed. Other information on the engine can be accessed using the touch keys (N, O and P). The hour meter feature shows the operating hours of the engine and should be used as a guide for scheduling periodic maintenance.
If the diagnostic gauge receives a trouble code from an engine control unit, the current display will switch to a warning or shutdown (depending on the severity of the code) screen that will display the trouble code number, the description of the code and the corrective action needed. Switch will be present, but may not be active, depending on engine controller (ECU) options originally selected. If switch is active, pressing the upper half of the override shutdown switch (G) will override an engine shutdown signal. The switch must be pressed within 30 seconds to prevent undesired shutdown of engine.
Pressing this switch will override the engine shutdown for 30 seconds at a time to move vehicle to a safe location. H—Bump Speed Enable Rocker Switch B—Tachometer This is a three-position switch (H) with the center position as (locked). With this switch in the position, the speed select switch (I) is also locked, to prevent accidental changes in operating speed. Pressing upper or lower half of switch (H) will unlock or enable the bump speed switch to take effect using speed select switch (I). The tachometer (B) indicates engine speed in hundreds of revolutions per minute (rpm). C—Voltmeter (Optional) The voltmeter (C) indicates system battery voltage.
The amber “Warning” light (P) will illuminate when battery voltage is too low for proper operation of the fuel injection system. I—Speed Select Rocker Switch The speed select switch (I) is used to bump engine speed up (+) or down (-) in small increments during operation. This switch must be used with the bump speed enable switch (H) in the unlocked position (top or bottom half of button depressed). D—Audible Alarm (Optional) The audible alarm (D) will sound whenever low oil pressure, high coolant temperature, or water-in-fuel conditions exist. This includes all signals that light up the amber “warning” indicator (intermittent alarm) or the red “stop engine” indicator (steady alarm).
J—High-Low Speed Select Rocker Switch The high-low speed select switch (J) is used to set the engine operating speeds at slow (turtle) or fast (rabbit). Factory preset idle speeds can also be adjusted using bump speed enable switch (H) with speed select switch (I). E—Audible Alarm Override Button The optional audible alarm has an override button (E) that silences the audible alarm for approximately two minutes when pressed. The basic instrument panel will have the high-low speed select switch only. Press and hold up (+) or down (-) to adjust engine speed as desired. The engine speed selected will not be held in the memory. To adjust engine speeds, See Changing Engine Speeds in Section 18.
F—Key Start Switch The three-position key start switch (F) controls the engine electrical system. When the key switch is turned clockwise to “START”, the engine will crank. Continued on next page OURGP11,000027C –19–25NOV03–2/3 17-2 021604 PN=65
