STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-09
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.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM
Circuits valid

Traction
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.

STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION

Start switch closed on power up after
initial key switch closure.
This status code will be displayed when P3 is greater
than 60% of battery voltage when the key switch is
closed.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Start switch input mis-adjusted or defective.
• Input voltage at P3 should be less than 60% of
battery volts at key switch closing. Adjust or
replace accelerator unit to insure that the
voltage at P3 is less than 60% of battery volts
before closing the start switch.
Short circuit between battery positive and P3 in
start switch input circuit.
• Disconnect wire from P3. Check for short
circuit from this wire to battery positive.
Defective control.
• Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero, if
not, replace control.
