Fendt 0.0.19 – A002 ECU or A005 ECU: Front power lift bus fault

The tractor's communication network (CAN-Bus) has lost connection with the front power lift control system, resulting in a bus failure and 'No functions available, no display' for the front power lift.

1. 1

   Check fuses F040 and F041 on the A013 printed circuit board (microfuses) for voltage supply issues

2. 2

   Verify that the A013 fuse board itself is receiving and distributing power correctly

3. 3

   Inspect the CAN-Bus wiring harness between the A013 fuse board and the A002/A005 ECU for breaks, chafing, or short circuits

4. 4

   Reference OEM Training 'Service Training EPC C (Document X990.005.023.026en)' for advanced diagnostics

1. 1

   Access the Fuse Panel

   Turn off the tractor ignition. Remove the interior panel on the right side of the cab to access the A013 printed circuit board (microfuse panel).

2. 2

   Inspect and Replace Fuses

   Locate fuses F040 and F041 on the A013 board. Test them with a multimeter for continuity. If blown, replace them with OEM-spec microfuses of the exact same amperage.

3. 3

   Test CAN-Bus Voltage

   Turn the ignition on and use a multimeter to verify that the CAN-Bus is receiving proper voltage from the A013 board.

4. 4

   Repair/Replace the A013 Board

   If the fuses are intact but there is no voltage output to the CAN-Bus, the A013 printed circuit board has likely failed internally. Remove the board and either send it out for mechatronic repair or replace it with a new OEM unit.

5. 5

   Clear Codes

   Once power is restored, use the tractor's terminal or the FENDIAS diagnostic tool to clear the 0.0.19 fault code and test the front power lift for proper operation.
