Case IH 15250 – Steering Valve Controller: Steering valve spool greater than command.

The actual position of the steering valve spool is more than 135 counts greater than the value commanded by the controller. This indicates a mismatch between where the controller is telling the steering valve spool to be and where it actually is.

1. 1

   Verify that the steering valve controller is configured for the correct steering valve type, as incorrect configurations can trigger related steering valve faults.

2. 2

   Inspect the steering valve for physical binding, contamination, or mechanical failure inside the valve that would prevent the spool from moving to its commanded position.

3. 3

   Inspect the wiring harness and connectors between the steering valve and the steering valve controller for corrosion, shorts, or open circuits that could distort the position sensor feedback.

1. 1

   Replace components

   Replace the Steering Valve or the Steering Controller if the spool is physically sticking or the internal position sensor has failed.

2. 2

   Perform calibration

   Perform a software calibration of the steering system using the dealer diagnostic tool (eTIM / HH menus).
