Aborting Powershift Transmission Calibration

The PTP shall abort calibration, and shall make no changes to stored calibration values in any of the following cases:

• If significant tractor motion is detected
• If the address number is incremented or decremented by the operator
• In the event of any calibration fault occurrence
• If the shift lever is moved out of gear
• If the engine speed moves above or below the limits required for calibration

If calibration aborts, all preexisting calibration numbers remain stored and in effect, whether they are the default values or values determined in a previous calibration. Calibration cannot be restarted from the point at which it was aborted.

Calibration shall be restarted only from the beginning. No new calibration numbers shall be stored until the entire calibration process completes, at which point the newly determined values for all clutches are stored.
