for
then disappears when the vehicle starts to
accelerate.
Traction
POSSIBLE CAUSE
Controller
Accelerator input mis-adjusted or defective.
?? Input voltage at P7 should be less than 4.2 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 negativ e 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 4.2 volts for solid
state type accelerator input
TRACTION
DESCRIPTION OF STATUS
STATUS CODE
Accelerator input voltage too low on

power up after initial key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.

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