Fendt 03.1.60 – MFA (Multifunction Armrest) control module: A039 - MFA, multifunction armrest

Invalid parameters for the REAR power lift module. Because the system cannot read the correct parameters, it defaults to using predefined/default values to maintain basic functionality.

1. 1

   Verify the active code 03.1.60 on the terminal display and check if the rear power lift is operating strictly on default values rather than responding to user-defined parameter adjustments.

2. 2

   Ensure there are no broader CAN bus communication errors between the MFA and the rear power lift module (which would typically trigger a '00.0.03' or similar bus fault).

1. 1

   Connect diagnostic tool

   Connect the FENDIAS diagnostic laptop/tool to the tractor's diagnostic port.

2. 2

   Navigate to MFA programming

   Navigate to the MFA (Multifunction Armrest) module programming section.

3. 3

   Perform EOL programming

   Perform an EOL (End-Of-Line) programming procedure.

4. 4

   Enter calibration code

   Specifically, enter Calibration code '8001' to rewrite the correct parameters for the rear power lift module into the MFA.

5. 5

   Clear fault code

   Clear the stored fault code from the system memory (note: each stored fault code must be cleared individually).

6. 6

   Test rear power lift

   Test the rear power lift to ensure it responds to user parameters and no longer relies on predefined values.
