STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-06
Accelerator depressed with no
direction selected.
This status code will be displayed while P4 and P5
are less than 60% of battery volts, and the accelerator
(P7) is calling for greater than 40% on-time.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Accelerator pedal is depressed before closing
forward or reverse directional switch.
•= Status code will disappear when directional
switch is closed or when accelerator pedal is
released.
Defective directional switch
•= Check forward or reverse switch to insure
closure when direction is selected.
Open circuit between directional switch(es) and
battery positive or between directional switch(es)
and P4 or P5.
•= Check all control wires and connections shown
in Trouble Shooting Diagram.

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 calling for greater
than 20% on-time at start-up.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Accelerator input mis-adjusted or defective.
•= Input voltage at P7 should be less than 20% of
learned span resistance. Adjust or replace
accelerator unit to insure that the voltage at P7
is correct.
•= Open wire between potentiometer negative
and P8
Defective Card
•= Replace controller unit.
