Calibrate Reverse Directional Clutch
To calibrate the reverse range directional clutch:
1. Move the speed control lever to the reverse
position.
2. Verify that the display shows a flashing “CC.”
3. Move the speed control to the right and hold it
there.
4. Observe the digital display. It will flash “20” for
approximately 4 seconds, then the number
displayed will increase by one digit for every
second until the reading becomes steady. A
steady reading indicates that the reverse range
clutch is calibrated.
5. Return the speed control lever to the neutral
position after the clutch is calibrated.
6. Verify that the digital display shown is flashing
“CC.”
EXIT CALIBRATION MODE
To exit the calibration mode:
1. Stop the engine and wait 10 seconds before
proceeding.
2. Start the engine in the normal manner.
3. Verify that with the speed control lever in the
neutral position, the digital display indicates
“N5.”
The tractor is now ready for normal operation.

PROGRAMMING FAULTS
Flashing “F”: Indicates that the CCM has detected
possible transmission output shaft rotation. This can
cause drive wheel movement. THE CALIBRATION
PROCESS WILL AUTOMATICALLY BE STOPPED.
To clear it, ensure the wheels are blocked and that
service brakes are applied. If the tractor is parked on
a slope, move the tractor to level ground.
Flashing “P”: Indicates that the park brake lever
was not applied before the calibration process was
started. To clear it, apply the park brake and restart
the calibration process.
“EH” Error High: During calibration process, the
initial application of the clutch occurred too quickly
and that the engine speed dropped the 14 RPM
before the constant had a chance to ramp up
normally. Ensure that all tractor accessories (air
conditioning) are turned off. If this continues, contact
your Buhler Versatile dealer.
“EL” Error Low: During the directional clutch
calibration, the CCM increased the constant number
to the maximum limit and the clutch did not load the
engine down by 14 RPM. The calibration process on
this clutch will automatically stop at that point. The
constant usually counts up to 99 and the “EL” shows
up. If this continues, contact your Buhler Versatile
dealer.
