Fendt 6.1.B0 – A004 Control Console: CAN-bus communication restricted.

Rear PTO (Power Take-Off) is non-operational. The system has detected a restriction or failure in the CAN-bus communication network specifically affecting the Rear PTO control circuit. The system explicitly flags that the module has lost its programming or synchronization and requires an End-Of-Line (EOL) reprogramming.

1. 1

   Check the voltage supply for the CAN-Bus on the A013 printed circuit board (fuse board)

2. 2

   Inspect fuses F040 and F041 on the A013 fuse board

3. 3

   Check the CAN-bus wiring harness between the A004 Control Console and the A002 ECU for chafing, breaks, or loose connector pins

1. 1

   Verify Hardware

   Ensure fuses F040 and F041 are intact and the A004 console is receiving power.

2. 2

   Connect Diagnostic Tool

   Connect the FENDIAS (Fendt Diagnostic System) laptop/tool to the tractor's diagnostic port.

3. 3

   Perform EOL Reprogramming

   Perform an End-Of-Line (EOL) programming procedure for the A004 Control Console / Rear PTO module to restore CAN-bus synchronization.

4. 4

   Clear Codes

   Once the EOL programming is successfully loaded, clear the stored fault codes from the memory.

5. 5

   Test Operation

   Start the tractor and test the Rear PTO engagement via the control console to ensure full functionality has returned.
