STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-09
Optional truck configuration - both the
forward and reverse directional
switches are closed at the same time.
This status code will be displayed when P4 and P5
are greater than 60% of battery volts at the same
time.

Controller
SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Forward or reverse directional switch welded
closed or mis-adjusted to be held closed.
· Replace or adjust directional switches to
insure that they open when directional switch
is returned to neutral.
Short circuit between battery positive and P4
and/or P5.
· Disconnect wires from P4 and P5 and check
wire for short circuit to positive side of
directional switch.
Defective Control
· Disconnect wires and measure voltage at P4
and P5. Voltage should be less than 60% of
battery volts.

DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-11
Accelerator volts too low on power up. This status code will be displayed when accelerator
volts are less than 1.7V at P7.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Defective accelerator pot.
· Measure the voltage from P9 to
NEG. Voltage should be between
4 to 4.8 volts. If not, disconnect
the wire from P9. Measure the
voltage from P9 to NEG. This
voltage should be greater than 4
volts; if not, replace the control.
· Disconnect wire from P7. Measure
voltage from the wire removed from
P7 to NEG. Voltage should be
greater than 1.9V, if not, replace
accelerator pot.
