1. 1

   Check the 12V supply to the Y065 solenoid valve using the tractor's circuit diagram (typically Sheet 9 or 14)

2. 2

   Perform an acoustic check near the accumulator as oil temperature rises; listen for a flowing sound indicating an emptying accumulator

3. 3

   Verify command override: Note that sending a cab command or externally energizing the Y065 valve will have no effect due to hydraulic pilot-operated non-return valves

1. 1

   Manually Release Pressure

   Locate the knurled-head screw on the MVFH [Y065] - Suspension raise solenoid valve and screw it in (open to the left) to manually release pressure. Caution: The chassis may lower immediately, and the rebound accumulator will be relieved.

2. 2

   Access the Valve

   Remove the metal panel at the right entry step to access the Y065 solenoid valve located on top of the central control block (ZSB).

3. 3

   Remove the Faulty Valve

   Disconnect the electrical harness from the Y065 valve and carefully unthread the valve body from the central control block.

4. 4

   Install the New Valve

   Install the replacement solenoid valve and reconnect the electrical harness.

5. 5

   Reassemble

   Close the manual release knurled screw and reinstall the metal access panel at the right entry step.

6. 6

   Clear Fault Codes

   Turn on the tractor and use the terminal (or FENDIAS / SERDIA diagnostic software) to confirm and delete the stored 15.1.62 fault code.
