1. 1

   Inspect the wiring harness and separation point connector X1679 for corrosion, backed-out pins, or damage.

2. 2

   Test voltage at the Y006 connector (Pin 3 / +supply): Ignition OFF should be 0 VDC, Ignition ON ~14 VDC, Engine Running (Brake not activated) ~2.8 VDC, and Actuation ~14 VDC.

3. 3

   Read out the KWP code using the SERDIA / Fendias diagnostic software to confirm the fault (often associated with FC:004A).

1. 1

   Locate the Y006 Solenoid Valve

   On 300/400 Vario models: It is located on the right side of the tractor on the engine bulkhead (open the bonnet to access). On larger/enhanced hydraulic models: It is located on the right side of the tractor on the valve block for the enhanced control hydraulics (remove the right rear wheel and metal guard to access).

2. 2

   Disconnect Electrics

   Disconnect the X1679 electrical connector from the Y006 solenoid valve.

3. 3

   Remove the Valve

   Unbolt and remove the faulty engine brake solenoid valve from the hydraulic/pneumatic circuit.

4. 4

   Install the New Valve

   Install the genuine Fendt replacement valve and torque the mounting hardware to OEM specifications. Always replace the lock nut if applicable.

5. 5

   Reassembly

   Reconnect the X1679 electrical connector. Reinstall the metal guard and the right rear wheel (if removed).

6. 6

   Clear Codes

   Connect the SERDIA / Fendias diagnostic tool and delete the error code (FC:004A) from the system.
