NOTE: The system may be configured to pre-
vent adjustment of the range levels.

The red system failure indicator light illuminates
if a system problem is detected. Press and hold
the volume control knob for 5 seconds to display
fault codes. The fault codes will be blinked out
as a pattern of flashes on this indicator light. See
Table 2.1 for fault codes.

6.
The green SC indicator light will flash 8 times if
the range knob is pressed to store accident re-
construction information. It will also flash 8 times
after the system is activated, after the power-on
LED test is finished, and if accident reconstruc-
tion data was previously stored.
7.
The photo light sensor senses lighting conditions
in the cab and automatically adjusts the intensity
of the indicator and alert lights.
8.
If the system’s configuration requires, insert the
driver’s identification card in the slot at the lower
front edge of the DDU. A high-pitched tone will
sound when the driver’s identification card has
been successfully read. One low tone will sound
if the driver’s card has been unsuccessfully read.
If so configured, a repeated low tone will sound if
the system is on and the requested driver’s card
has not been inserted.
9.
The yellow alert light illuminates when an object
is detected within the system’s maximum range
of 350 feet (107 meters) on a straight road.
Range is reduced in curves by the turn radius of
the curve. This light also illuminates when the
proximity alarm threshold is crossed.
10.
The yellow and orange alert lights illuminate
when your vehicle is within a 3-second following
interval behind another vehicle in the same lane.
If you are within a 2-second following interval,
and closing on the vehicle ahead, a warning tone
will also sound.
11.
The yellow, orange, and red alert lights illuminate
when you are 1 second (and less than 1 second)
behind a vehicle. If the vehicle ahead is opening
the interval, no tone will sound. If you are closing
the interval, double tones will sound. Within a
1/2-second or less following interval, opening or
closing, the tones will repeat twice per second.
12.
If a stationary vehicle or object, or an object
moving less than 3.4 mph (5.5 km/h) in the same
lane is detected within 220 feet (67 meters) and
within 3 seconds, all three alert lights will illumi-
nate and the double tones will sound. This warn-
ing overrides all others and is not affected by the
range control knob setting.
IMPORTANT: The system is disabled in turns
with a radius of less than 750 feet (230 meters)
and when the brakes are applied.
13.
If your vehicle is traveling less than 2 mph (3
km/h) and an object is detected less than 15 feet
(4.5 meters) in front of your vehicle, and the
closing rate is more than 1/2 mph (1 km/h), the
yellow alert light will illuminate and a low-
frequency double tone will sound. This is the
proximity alert.
NOTE: All warnings apply only to objects within
the maximum detection range and in your lane.
Proximity alert tones and vehicle-closing 1/2-
second and 2-second following interval tones
are configured items. All tones are disabled in
sharp turns or when the brakes are applied. If
the configuration permits, the 3-second and
2-second alert levels may be adjusted with the
range control knob. A single low-frequency tone
sounds when a system failure is detected. A
