TRIP DATA RECORDER (TDR)

TDR is a standard dashboard-mounted graphic
device that displays and records operational
data transmitted by the Detroit Diesel Electronic
Controls (DDEC) and other electronically
controlled engines on the SAE J1708/1587
diagnostic data link. TDR uses a dashboard
integrated liquid Crystal display. It provides
automated intensity control of the display, based
on the dashboard instrument panel lights for
improved driver convenience.

Many driver friendly features are designed into
TDR to provide instantaneous feedback to the
driver. This enables the driver to understand the
effect of actions on engine and vehicle
performance. Two display screens
(automatically shown) offer real-time feedback
based on the vehicle's activity. When in motion,
the "Fuel Economy" screen displays fuel
consumption versus the fleet's target. When
stopped, "Idle Percentage" time versus fleet's
target is indicated. Should an alert message be
sent out by the ECM, the driver will be shown
what is wrong and how engine power will
change.
Five different modes are available for viewing on
the screen:
• Multi-Function;
• Diagnostic;
• Set-Up;
• Gauge Display;
• Fuel Economy.
To change from one mode to another, press the
MODE button. Each mode contains sub-displays
with information related to the selected mode.
These can be accessed using the UP/Down
arrow buttons. If a display contains a value that
can be changed, pressing the SET button
enables the change and selects the digit to be
changed. At this point, choosing a value is done
with the UP/DOWN arrow buttons. To accept a
change, press SET again.
Note :
Diagnostic and set up modes are not
available when the vehicle is in motion. If such a
mode is in use and the vehicle reaches a speed
of 5 mph (8 km/h), the screen will automatically
revert to clock display.
Warning :
If the vehicle is in motion, reach
around the steering wheel with the left hand to
access the control buttons. Accessing the
buttons through the steering wheel can result in
injury or death due to loss of vehicle control.
Multi-Function Mode
The multi-function mode contains a clock, an
alarm clock, two independent trip odometers
and an engine hourmeter.
Clock Display
The clock displays the current time in either a
12-hour format (12:00:00 a.m. to 11:59:59 p.m.)
