STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-08
Accelerator input voltage too low on
power up after initial key switch
closure. This status code will be displayed when the
accelerator input voltage at P7 is less than 3.0 volts,
and any of the following connections are opened and
closed: battery plug or key switch.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM

Traction
Controller
SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Accelerator input mis-adjusted or defective.
• =
Input voltage at P7 should be more than 3.0
volts. Adjust or replace accelerator unit to
insure that the voltage at P7 is more than 3.0
volts before depressing pedal.
Short circuit between battery negative and TB1
in accelerator input circuit.
• =
Disconnect wire from P7. Check for short
circuit from wire to battery negative.
Resistance should be greater than 4.7K ohms.
Defective control.
• =
Disconnect wire from P7. Measure voltage
from TB1 to negative. Voltage should be
greater than 4.5 volts, if not, replace control.

STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-09
The travel enable switch is open and
the directional switch is closed. This status code will be displayed when P5 is less
than 12% of battery volts and P4 is greater than 12%
of battery volts.

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.
