OM3245 8/11
C6. Propel System Not Ready
This amber indicator light functions
during start-up much like the
hourglass icon on a computer
screen. This light indicates the
computer is in the process of
performing the self-diagnostics
and set-up functions at start-up.
Propulsion will not be available at this time.

D6. Reduced Propulsion

This amber indicator
illuminates if the full AC drive
system performance in propulsion
is not available. At this time, the
only event that should activate this
light is the use of "limp home"
mode. This mode of operation
requires a technician to enable.

E6. Retard At Continuous Level

When the drive system detects that
any of its components has reached
maximum temperature, this amber
indicator light will flash for 15
seconds, then illuminate steadily
when the retarding performace is
limited to the continuous level. The
operator should control the speed of the truck in
accordance to the "continuous speeds" on the grade/
speed chart.

E7. Maintenance Monitor

This amber indicator light will
illuminate if a "repair" fault is
detected, which must
corrected after the operator's
shift is done.

8. Brake Test Switch

This switch is used to initiate a
brake test. Press the momentary
switch to enter the brake test
mode. If certain conditions are
met, the operator can enter a
brake test sequence.
