John Deere Instrument (Gauge) Panel (Electronically Controlled Engines) (Continued)

J—Key Switch (Option A)

The main station instrument panel has a two-position (OFF/ON) key switch (J) which controls the engine electrical system, starts and stops the engine. When the switch is in the “ON” position, the engine may be started by pressing the start button (I).

The remote station instrument panel has a start/stop rocker in place of the key switch. With the key switch on the main station instrument panel in the ON position, the engine can be started and stopped from the remote station instrument panel.

J—Key Switch (Option B)

The main station instrument panel has a three-position (OFF/ON/CRANK) key switch (J) which controls the engine electrical system, starts and stops the engine.

The remote station instrument panel has a stop button in place of the key switch. With the key switch on the main station instrument panel in the ON position, the engine can be started and stopped from the remote station instrument panel.

K—Diagnostic Gauge/Hour Meter

The diagnostic gauge (K) displays diagnostic trouble codes (DTCs) as they are accessed. Other information on the engine can be accessed using the touch keys (L, M, and N). 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 switches 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. (Refer to the following pages for use of the diagnostic gauge or OEM Diagnostic Gauges Operator’s Manual OMDZ109098.)

L—Menu Key

The menu key is pressed to either enter or exit the menu screens.

Pressing the left arrow to scroll to the left or upward or the right arrow to scroll to the right or downward. This will allow you to view various engine parameters and any diagnostic trouble codes that occur.
