EPC 000630.14 – Incorrect Calibration Value

EPC 000630.14 (EPC 630.14)

Code: 000630.14

Shortcode: 630.14


This error code, EPC 000630.14, is generated when one or more calibration values (forward clutch fill pressure, reverse brake fill pressure, forward clutch fill time, reverse brake fill time) are out of the allowed range. This indicates that the transmission system calibration is incorrect.


When this error is detected, the transmission may not operate correctly, leading to poor performance, incorrect shifting, and potential damage to the transmission components.


Recalibrate the Transmission:

  • Perform a thorough recalibration of the transmission system using the manufacturer’s recommended procedure to ensure all values are within the allowed range.

Inspect Calibration Tools:

  • Verify that the tools and equipment used for calibration are functioning correctly and providing accurate measurements.

Check for Software Updates:

  • Ensure the control unit software is up-to-date. Software updates may contain improvements or fixes for calibration issues.

Inspect Transmission Components:

  • Check the condition of the transmission components involved in the calibration process (clutches, brakes, sensors) for any signs of wear or damage. Repair or replace as necessary.

Reset and Test System:

  • After recalibrating, reset the system and test the transmission to ensure proper operation and that the error code does not reoccur.


Accurate calibration is crucial for the proper functioning of the transmission system. Regular maintenance and using the correct calibration procedures can help prevent such issues.
