DESCRIPTION OF STATUS
STATUS CODE
The accelerator pedal is depressed with
-06
no direction selected.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.

POSSIBLE CAUSE
Traction Accelerator pedal is depressed before closing
forward or reverse directional switch.

DESCRIPTION OF STATUS
STATUS CODE
Accelerator voltage input is too high on
-08
power up after initial key switch
closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate
Circuits valid
for
POSSIBLE CAUSE
Traction
Accelerator input is mis-adjusted or
Controller
defective.
•=Input voltage at P7 should be less than
1.24 volts. Adjust or replace accelerator
unit to insure that the voltage at P7 is
less than 1.24 volts before depressing
pedal.
Disconnect wire from P7. Check for short
circuit from wire to P15. Resistance should
be greater than 3.5K ohms.
Open circuit at P8 or open potentiometer
wiper at P7 – verify continuity of wiring at
both points.
CORRECTIVE ACTIONS
Status code will disappear when
directional switch is closed or when
accelerator pedal is released.
Check forward or reverse switch to insure
closure when direction is selected.
Check all control wires and connections
shown in trouble shooting diagram.
CORRECTIVE ACTIONS
CAUSE OF STATUS INDICATION
This status code will be displayed when the
accelerator voltage, at P7>1.5V, and no direction is
selected (P4 and P5 are both less than 7.2V)
