2. 2

   Check for excessive hydraulic fluid temperatures (especially if the controller is mounted directly to the hydraulic steering valve)

3. 3

   Inspect the steering valve controller for internal electrical shorts

1. 1

   Replace the Steering Valve Controller (SVC)

   If the controller is internally overheating and cannot be cooled, replacement of the SVC is typically required.
