Fendt A.1.2C – A002 ECU: Spool valve fault, valve 2 — Floating position has been set manually

The system has detected that the auxiliary control valve #2 (component designation Y016, color-coded blue) has been manually deflected into the floating position using the mechanical override on the valve block, rather than being triggered electronically via the cab controls.

1. 1

   Verify with the operator if they intentionally used the manual override lever on the #2 (blue) rear spool valve to force it into float mode.

2. 2

   Inspect the manual actuator on the Y016 valve block to ensure it has no play and springs back to the center (neutral) position by itself.

3. 3

   Check if the main piston is physically stuck in the deflected position, which is commonly caused by hydraulic oil contamination.

1. 1

   Acknowledge the Code

   Note that the direct system consequence of code A.1.2C is 'No consequences,' as it is an informational code rather than a hard failure.

2. 2

   Clear the Code

   If the valve was intentionally put into the floating position manually, no repair is necessary. Simply return the valve to neutral and clear the fault code from the tractor's memory.

3. 3

   Free a Stuck Valve

   If the code persists and the valve is stuck in the float position without operator intervention, carefully manipulate the manual override to see if it is binding.

4. 4

   Clean or Replace

   If the main piston cannot return to the neutral position due to internal binding or heavy oil contamination, the Y016 valve section must be removed and either thoroughly cleaned or replaced.
