Fendt 0A.1.FA – Hydraulics Control System (Electrical Valves module): S067 - Switch (external), valve actuation, raise

This fault code indicates a signal fault or a faulty button on the external hydraulic valve actuation circuit. Specifically, the S067 switch (the "raise" button, typically located on the rear mudguard/fender) is sending an implausible signal, has a wiring break/short, or is physically stuck.

1. 1

   Inspect the S067 external raise button on the rear fender for physical damage, dirt ingress, or sticking

2. 2

   Ensure the S068 (lower) button is not also stuck (simultaneous actuation triggers a related fault 0A.1.FC)

3. 3

   Inspect the wiring harness from the S067 switch to the control unit for breaks, chafing, or short circuits

4. 4

   Turn the tractor off completely and perform a cold start to see if the system resets and clears the fault state

1. 1

   Turn off the tractor ignition and disconnect the battery to protect the electronic control modules.

2. 2

   Locate the S067 external raise switch on the rear mudguard/fender.

3. 3

   Carefully remove the switch from its housing and disconnect the electrical connector.

4. 4

   Use a multimeter to test the switch for proper continuity when pressed and released.

5. 5

   If the switch is stuck closed or open, it has failed internally and must be replaced.

6. 6

   If the switch tests fine, trace the signal line wiring back to the hydraulic control module to repair any damaged wires or corroded connectors.

7. 7

   Install the new OEM replacement switch into the fender housing and reconnect the wiring harness.

8. 8

   Reconnect the battery and perform a cold start (cycle the ignition off and on) to clear the fault code from the ECU.

9. 9

   Test the external raise and lower buttons to confirm proper hydraulic operation.
