DIAGNOSTIC STATUS CODES
IT TRANSISTOR CONTROL
TRACTION
STATUS CODE
Both the forward and reverse switches or
-09
the turf and reverse switches are closed at
the same time.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
for
POSSIBLE CAUSE
Traction
Forward or reverse or turf switch welded closed
or mis-adjusted to be held closed.
Controller
 Replace or adjust directional switches to insure
that they are open when switch is returned to
neutral or off.
Short circuit between battery positive and P4,P5
and/or P6.

check wire for short circuit to positive side of
directional switch
Defective control.

Disconnect wires and measure voltage at P4,
P6 and P5. Voltage should be less than 50%
of battery volts, if not, replace control.
TRACTION
STATUS CODE
Start switch closed on power up after initial
-11
key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
for
POSSIBLE CAUSE
Start switch is mis-adjusted or defective.
Traction

Controller
Short circuit between battery negative and P3 in
start switch input circuit.

Defective control.

DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
Disconnect wires from P4, P6 and P5 and
DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
Input voltage at P3 should be greater than 2.5
volts at key switch closure. Adjust or replace
accelerator unit to insure that the voltage at
P3 greater than 2.5 volts before closing the
start switch.
Disconnect wire from P3. Check for short
circuit from this wire to battery negative.
Resistance should be greater than 20K ohms.
Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be 2.5 to
5.0 volts. If not, replace the control.
CAUSE OF STATUS INDICATION
This status code will be displayed when P4 and
P5 or P6 and P5 are greater than 50% of battery
volts.
