SV2 004085.07 – SV II Not in Neutral Position

SV2 004085.07 (SV2 4085.07)

Code: 004085.07

Shortcode: 4085.07


The error code SV2 004085.07 indicates that the Selective Control Valve II (SV II) is not in the NEUTRAL position. This can occur due to mechanical issues, electrical faults, or if the control lever is moved while the key is on and the engine is off.



When this error code is triggered, the equipment may experience issues with hydraulic function control, leading to erratic behavior or inability to perform specific tasks that require the valve to be in the NEUTRAL position.


Inspect Mechanical Components:

  • Check for any mechanical obstructions or damage to the valve that may prevent it from returning to the NEUTRAL position.
  • Ensure that the valve is free from debris and other blockages.

Verify Control Lever Position:

  • Ensure the control lever is in the NEUTRAL position when turning the key on. Avoid moving the control lever with the key on and engine off.

Check Electrical Controls:

  • Verify that the electrical control system is functioning correctly.
  • Inspect wiring and connections for any damage or corrosion. Repair or replace as necessary.

Calibrate the Valve:

  • Perform calibration procedures to ensure the valve can accurately return to the NEUTRAL position.
  • Follow the manufacturer’s guidelines for proper calibration procedures.


Regular maintenance and calibration of the SV II and related control systems are crucial to ensure reliable operation and to prevent issues with achieving the NEUTRAL position.
