MDI Description
Located in the battery compartment on the left side of the
machine (See Figure 3-3.) is a Multifunction Digital Indicator
(MDI). The purpose of the MDI is to display Diagnostic Trouble
Codes (DTC) when a functional problem occurs with the
machine. The MDI is plugged into the diagnostic connector in
the battery compartment.
When a problem occurs:
1. A Wrench Icon will display on the Diagnostic Trouble
Code LCD display.
2. A three to five digit DTC will display on the Diagnostic
Trouble Code LCD display, below the wrench icon.
NOTE: When more than one DTC exists, each DTC will be dis-
played on the LCD for 3 seconds before changing to the
next DTC. Once the last active DTC is displayed, the display
will recycle indefinitely until the DTC’s are corrected.
3. The red Fault LED will illuminate (this does not apply
to 00x DTC’s; the Fault LED will not illuminate for these
DTC’s).
NOTE: For DTC’s and descriptions, refer to Section 4.13, Diagnos-
tic Trouble Codes (DTC) Check Tables.
Also located on the MDI are Battery Discharge Indicators (BDI).
These green LEDs indicate the level of charge in the batteries.
NOTE: When the batteries are completely discharged, the LED in
the 0-25% range "red area" will flash.
• The BDI will convey the same information as the BDI on the
platform control station. (see Figure 3-3., Platform Control
Station)
• Under normal driving conditions the BDI’s will be illumi-
nated. When a DTC exists (other than 00x DTC’s) the BDI
LEDs will not be illuminated.
