SECTION 7.0 AUTOCALIBRATION OF ACCELERATOR
POTENTIOMETERS
When calibrating the accelerator pot, program Function 6
with a handset to a value between 15 and 20, and then exit
programming mode. Cycle the key switch on and off to
store the function setting, and leave the handset plugged in.
When returning the key switch to the “ON” position, make
sure that the forward, reverse and start switches are open,
and that the seat switch is closed. If one of these
conditions is not met, an “-83” status code will appear the
dash display. Once all of the above conditions have been
met, four “A”’s will appear on the handset.
AAAA
When the four “A” ’s are displayed, close the forward
directional switch, with the accelerator pedal fully
released. The dash display should show three “A” ’s:
AAA
Return the forward switch to the open position, and the
dash display should show two “A” ’s:
AA
Fully depress the accelerator pedal and close the forward
switch. Only one “A” should be displayed:
A
Re-open the forward switch. The truck will either return to
a normal operating state or an “-86” status code will
appear on the handset. If the “-86” code appears, either
the full accelerator pedal voltage was greater than 4.5
volts, or the voltage span from no pedal depression to full
pedal depression was less than 2.6 volts. Either condition
requires external adjustment to the accelerator pot prior to
repeating the process above.
The auto-calibration routine is now completed.
