Hydraulic malfunction in the secondary hydraulic system.
Check the secondary hydraulic circuit for failure in the flow switch, the connectors, wiring, electro-hydraulic pump, and hydraulics.
What you'll see
The back-up system for the primary hydraulic system for power steering is not functional. * A warning will be displayed in the ICL. * If a simultaneous sensor malfunction in the primary hydraulic system is present, a (different) warning will be displayed in the ICL. * If a simultaneous hydraulic malfunction in the primary hydraulic system is present, a (different) warning will be displayed in the ICL.

Diagnostic depth
The flow switch of the secondary hydraulic system for power steering does not indicate a flow though there should be a flow.
• Hydraulic malfunction o defect pipes, o defect electro-hydraulic pump, or o defect power steering gear. • Defect wiring o loose connectors, o open circuit on sensor ground • Defect sensor
