Hydraulic Pump Electric Power Steering System: Fail-Safe
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 power steering warning lamp to warn the driver that the hydraulic pump electric power steering system is in the manual steering state.
