(2) Calibration Procedure
NOTE: The select button (see Figure 6) on the front of the fuel quantity module analog
indicator being calibrated will be used to set the calibration points and advance to the
next step.
(a) Add one (1) gallon (unusable) fuel to the left tank and allow the instrument and fuel to
settle for two (2) minutes.
NOTE: At each calibration step, vibrate the tank by bumping its lower surface.
(b) After two (2) minutes, the green and yellow LED’s on the module indicator will be flashing
alternately, the EDI will display “0” and the analog gauge will display “E” (see Figure 5).
(c) Press the left “SEL” button and hold for two (2) seconds. If the sensor is in tolerance for
the step being recorded, the LED’s will stop flashing and remain on, the external alarm
will sound and the EDI display and the fuel quantity module pointer will advance to the
next step. The external alarm will continue to sound as long as the “SEL” button is held.
NOTE: If the sensor is out-of-range for the calibration step being programmed, then
pressing the left “SEL” button will not advance the module to the next step.
(d) The calibration step sequence is: “E”, 5, 15, 30, 45, and “F”.
(e) When the module advances to the next step, normally only the yellow LED will flash until
fuel is added.
(f) Add the appropriate amount of fuel for the fuel point displayed. Do not press the left “SEL”
button when the green LED starts to flash. Allow the fuel and module to settle for two (2)
minutes, then press the left “SEL” button and advance to the next step.
(g) When 60 gallons of fuel have been added and a two (2) minute settling time has passed,
press the left “SEL” button. When you release the button, only the green LED will be
flashing. This indicates that the calibration is finished.
