Diagnostic Indicator Lights
On-board Diagnostics:
All “M” and “R” Series ZTrak’s use a VCU (Vehicle
Control Unit) allowing on-board vehicle diagnostics to
assist in troubleshooting.
There are two different VCU’s depending on the series:
• “Basic” VCU’s are used on all “M” Series.
• “Extended” VCU’s are used on all “R” Series.
“Extended” VCU’s incorporate comfort and
convenience diagnostics as well as engine oil
pressure input.
• If a malfunction exists, the VCU will blink out
codes to the VDL (vehicle diagnostic light) on the
instrument cluster.
Both “Basic” and “Extended” VCU’s display two types
of codes to the VDL:
DTC’s (Diagnostic Trouble Codes) check:
• Safety Interlock Violations
• Electrical System Real Time Faults
DTMC’s (Diagnostic Test Mode Codes) check:
• Integrity of the switches, sensors, wiring and VCU
hardware.

A
Vehicle Diagnostic Light – VDL (A)
Vehicle DTC’s will be displayed when the VCU does
not see the correct and/or desired inputs to start the
engine, engage or run the PTO, or the operator leaves
the seat with the engine running.
Engine Diagnostic Indicator Light – EDL (B)
(EFI Models only)
• EFI Models also use both a VCU and a ECU (Engine
Control Unit).
• Light will be on if active diagnostic code(s) are
present.
NOTE: See your authorized John Deere Dealership if
the EDL is on.
Engine Oil Pressure Indicator Light (C)

Vehicle DTMC Information
DTMC’s are displayed by entering the Diagnostic Test Mode. Before entering the Diagnostic Test Mode, it is
best to turn off all switch INPUTS (i.e., brake not locked, PTO switch not in the engaged position, operator not
in seat, etc.). Once all the INPUTS are off, the operator can enter the Diagnostic Test Mode by cycling the key
switch quickly from OFF to RUN exactly three times. On the third cycle leave the key in the RUN position.
Upon entering the Diagnostic Test Mode, the vehicle control unit will perform an automatic diagnostic check. If
there are no system faults and no inputs detected, the display should flash a 1-1 Code.
Instructions on how to remove the Fault/Input Codes in order to achieve a 1-1 Code:

Operating Tips – Safe Operation
on Slopes
Operate machine with extreme caution on hills,
slopes, and rough terrain to avoid losing traction
and minimize rollover risk. Mowing sites should
be carefully surveyed to assure slopes are safe for
machine operation. Consider moisture and turf
conditions. Wet slopes present significantly higher
risk even though they may have been mowed
successfully before. Look for dips and holes along
the slope that could change the angle of vehicle
operation.
Determining Safe Slope Angles:
1. Lay straight piece of sturdy lumber 4 ft (1.2 m)
long on slope.
2. Measure slope angle with angle indicator or
protractor level.
3. Repeat procedure at several points on same slope.
• Never mow or operate machine on slope angles
greater than 20°.
• Exceeding the maximum recommended slope
angle of 20° increases the risk of rollover
accidents that can result in serious injury or
death.
• Always consider potential turf conditions and
slope angles when determining the risk of loss-ofcontrol and tip-over accidents.
• On slope angles of 10° or less the risk of rollover is
low, but as the slope angle increases to the John
Deere recommended maximum of 20° the risk
increases to a moderate level.
When Operating on Slope
• Wear seat belt when operating machine with the
ROPS in the UP position.
• Keep tires properly inflated. Improper pressure
can cause machine to lose traction and become
unstable on slopes.
• Mowing sites should be surveyed to identify
slopes safe for machine operation. Consider
potential turf conditions, dips, and holes along
with slope angles when determining a safe slope.
• If machine is operated on a steep slope, rollover
can occur before tires lose traction.
• When possible, mow across a hill rather than up
and down it with a ZTrak.
• Decrease speed and use caution when making
turns and when changing directions on slopes.
Sudden changes in speed or direction could cause
machine to roll over.
• Do not mow near drop-offs, ditches,
embankments, or bodies of water. Machine could
suddenly roll over if wheel goes over edge or edge
caves in. Leave a safety area between machine
and any hazard.
• Use caution when operating machine on wet or
loose turf. Tires may lose traction.
• Use lower speeds when mowing and operating on
slopes. Decrease speed as slope angle increases.
