Power Steering Control Module: Fail-Safe
WARNING: This page is about a different car, the 2017 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
When an error occurs in the hydraulic pump electric power steering system, fail-safe brings the system to a halt (manual steering) or restricted (constant steering assist level) state. When the system is in a halt state, fail-safe turns ON the hydraulic pump electric power steering warning lamp to warn the driver that the hydraulic pump electric power steering system is in the manual steering state.
