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

POSSIBLE CAUSE
Traction
Accelerator input is mis-adjusted or
Controller
defective.
 Input voltage at P7 should be less than
0.9 volts. Adjust or replace accelerator
unit to insure that the voltage at P7 is
less than 0.9 volts before depressing
pedal.
Open circuit at P8 or open potentiometer
wiper at P7 – verify continuity of wiring at
both points.

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.
