Code C0571 on the 2023 Ram 2500 indicates the power steering fluid level has dropped below the acceptable threshold. The Ram 2500 uses a hydraulic power steering system appropriate for its heavy-duty work truck application, and this code alerts you to a potentially serious loss of steering assist fluid.
Hydraulic System in Heavy-Duty Applications
The Ram 2500's hydraulic power steering provides the robust assist needed for steering large tires, heavy loads, and fifth-wheel towing. A belt-driven pump pressurizes fluid in the system. Fluid level loss indicates a leak that must be found and repaired to prevent steering assist loss.
Warning Significance
With C0571, a power steering warning appears on the dashboard. If fluid level is significantly low, you may notice increased steering effort or intermittent loss of power assist, especially during tight turns or parking maneuvers. Continuing to drive with low fluid can damage the pump and other components.
Leak Detection
Power steering fluid leaks commonly occur at high-pressure hose connections, the pump shaft seal, the steering gear input shaft seal, or the cooling line fittings (if equipped). Check the fluid reservoir first to confirm low level, then perform a visual inspection with the engine running. Common leak spots show fresh wet fluid or accumulated dried residue.
Repair Requirements
After finding and repairing the leak source, refill the system with the specified power steering fluid for Ram trucks. Bleed air from the system by cycling the steering wheel full lock to full lock with the engine idling. Recheck fluid level after bleeding, as air pockets can give false readings.
