5-2.12 “Fuel Correction Adjustment” Screens
5-2.12.1 The 3176B, 3176C, C-10, C11, C-12, C13, C15, C-15, C-16,
and 3406E Engines Only
The “Fuel Correction Adjustment” allows the fi ne tuning of data on future fuel usage that is based on the past differences of
values. The values are stored in the ECM and the recorded fuel usage.
5-2.12.2 Accessing “Fuel Correction Adjustment”
An ECM Customer Programmable Parameter determines access to this function of the dash display. If the ECM is not
programmed to allow access to this screen, the entire “Fuel Correction Adjustment” column of the “Screen Map” will not
be shown. Press the Right arrow button from the “THEFT DETERRENT” title screen or press the Left arrow button from the
“DISPLAY CONFIGURATION” title screen in order to pass over the “FUEL CORRECTION ADJUSTMENT” title screen. After the
parameters are programmed in the ECM, power to the display must be turned OFF and the power turned ON again in order
for the display to recognize the change.
“Fuel Correction Adjustments” should be made following extensive operation of the vehicle. During this period, the
vehicle should be operated in the usual manner. The “Fuel Correction Adjustment” affects all future “Fuel Used” data,
“Instantaneous”, “Driver Trip”, “Fleet Trip”, and “Lifetime Totals”. The “Fuel Correction Adjustment” should be made when the
vehicle is not moving.
5-2.12.3 “Adjusting Fuel Correction”
Determining Actual Fuel Economy
The actual fuel usage and travel distance must be recorded in order to make an accurate adjustment. The display uses the
“Fleet Trip Segment” as a basis for “fuel correction adjustment”. The actual fuel usage and the travel distance should be
recorded immediately after a “Fleet Trip Segment Reset”. Calculate the “Actual Fuel Economy” after driving on a typical route
for an extended period of time. Calculate the fuel economy from the “Fuel Used” and “Distance Traveled” per the following
formula.
Actual Distance Traveled
Actual Fuel Used
Entering Actual Fuel Economy
From the “FUEL CORRECTION ADJUSTMENT” title screen, press the Down
arrow button. The display will show the current “Fleet Fuel Economy” on
the top line. The display will show a fl ashing cursor near the left digit next
to the word “ACTUAL” on the second line of the display.
Pressing the Down arrow button scrolls through numbers 0 to 9 beginning
with 9. Pressing the Up arrow button begins with the number 1. If the fi rst
position is not needed, press the Right arrow button. The space for the
second digit will be highlighted. When the appropriate number is viewed,
press the Right arrow button and select the digit after the decimal point.
When the last digit is successfully selected, press the Right arrow button.
The display will indicate the “Actual Fuel Economy” that was entered. If the
number is correct, press the Left arrow button.
If the “Actual Fuel Economy” is correct, press the Left arrow button. A
message will appear to verify the “fuel correction adjustment”. If the value
for “Actual Fuel Economy” was entered incorrectly, press the Down, Up,
or Right arrow button. The display will return to the “FUEL CORRECTION
ADJUSTMENT ENTRY” screen. The numbers that were previously entered
will be deleted from the screen. The display will allow the value for the
“Actual Fuel Economy” to be re-entered on the screen.
“Fuel Correction Out-of-Range” Message
The “FUEL CORRECTION OUT OF RANGE” message will be displayed if the
value for the “Fuel Rate Correction” exceeded the allowable limits. Press
any button in order for the display to return to the “FUEL CORRECTION
ADJUSTMENT” title screen.
