IMPORTANT: Care should be used during diagnostic
procedures to avoid damaging the
terminals of connectors, sensors, and
actuators. Probes should not be poked
into or around the terminals or damage
will result. Probes should only be
touched against the terminals to make
measurements.
Diagnosis of the Deere electronic control system on
engines with Deere electronic instrument panel (shown)
should be performed as follows:
1. Make sure all engine mechanical and other systems not
related to the electronic control system are operating
properly.
NOTE: Liquid Crystal Display [LCD] will always default to
last menu item. If an active Diagnostic Trouble
Code (DTC) is present, display will alternately
flash from the hour meter reading to DTC(s).
The code number will appear on the first line and
the words SrvcCode on the second line. Active
DTC(s) can be viewed by selecting “SrvcCode” on
the menu and pressing both touch switches at the
same time. Pressing touch switches (B) and (C)
scrolls through various engine parameters and
diagnostic trouble codes.
2. Read and record DTC(s) displayed on LCD of
diagnostic gauge (A). For procedure to access diagnostic
trouble codes, refer to “Using Diagnostic Gauge to Access
Engine Information”, earlier in this manual.
3. Go to the LISTING OF DIAGNOSTIC TROUBLE
CODES (DTCs) later in this section, to interpret to the
DTC(s) present.
4. Contact your nearest engine distributor or servicing
dealer with a list of DTC(s) so that necessary repairs can
be made.
