speed dial calibrations involve submodes c01 and submode c02.Note: Always perform both the full clockwise calibration and the full counter-clockwise calibration for the speed dial.
Turn the key start switch to the ON position. Do not start the engine.
Enter calibration mode 2 on the ECM display. To do so, press and hold the ECM Mode switch until “- 2 -” is showing in the display area. Submode c01 should be displayed which will confirm that the calibration mode has been entered.
Submode c01 should be displayed if the machine is in calibration mode and the engine is not running. If submode c01 is displayed, go to Step 5. If submode c01 is not displayed, go to the next step.
Enter submode c01 (speed dial full clockwise). In order to do so, press and hold the display mode switch in the increment position until “c01” is displayed.
Ensure that the speed dial is in the full clockwise position.
Store the value of the signal currently being sent from the speed dial sensor. In order to store the value, press and hold the display mode switch in the CLEAR/STORE position. While the switch is pressed, the red indicator (not accepted) or the amber indicator (accepted) will briefly flash. Observe the status of these indicator's while the switch is in the CLEAR/STORE position. Release the display mode switch. If the amber indicator flashed (accepted), perform the next calibration.If the red indicator flashed (not accepted), check that the speed dial is in the full clockwise position. Refer to the “PWM Sensor Calibrations Are Not Accepted” module in this section of the manual. Repeat Step 6. If the red indicator is flashing again or if a diagnostic code CID 012 FMI
