STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-05
Accelerator depressed without
selecting travel enable switch. This status code will be displayed when P4 and P5
are less than 12% of battery volts, and P7 is less than
2.5 volts.

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
-07
Accelerator input voltage too high on
power up after initial key switch
closure. This status code will be displayed when the
accelerator input voltage at P7 is higher than 3.7
volts, and travel enable switch is selected.

SYMPTOM
Control will not operate when accelerator pedal
is depressed or status code -07 is displayed
then disappears when the vehicle starts to
accelerate.
POSSIBLE CAUSE
Accelerator input mis-adjusted or defective.
•
=
Input voltage at P7 should be less than 3.7
volts. Adjust or replace accelerator unit to
insure that the voltage at P7 will vary from 3.5
volts to less than .5 volts when the pedal is
depressed.
Open circuit between battery negative and P7 in
accelerator input circuit.
• =
Check for broken wires or loose connections
or open potentiometer / voltage supply.
Short circuit from battery positive to wiring in
accelerator input circuit.
• =
Disconnect wire from P7 and measure
voltage at wire to negative. Should be zero
volts for potentiometer type and less than 3.7
volts for solid state type accelerator input.
