The 2015 Ford Explorer represents a significant evolution for the iconic three-row SUV, blending refined dynamics with robust capability. At the heart of this driving experience is the power steering system, a critical component that translates driver input into precise wheel movement. Understanding the specifics of the 2015 model's power steering is essential for owners, as it directly impacts handling, safety, and overall vehicle maintenance.
Electronic Power Steering System
Unlike older hydraulic systems, the 2015 Ford Explorer utilizes an Electric Power Steering (EPS) configuration. This modern system uses an electric motor to assist steering, eliminating the need for a traditional hydraulic pump, belts, and fluid reservoir. The primary advantage is efficiency; because the motor only activates when steering input is detected, it reduces parasitic drag on the engine, contributing to better fuel economy. Furthermore, EPS allows for advanced tuning, enabling features like variable assist that make parking effortless and high-speed cruising feel stable and planted.
Integration with Safety and Stability Technologies
The 2015 Explorer’s power steering system is deeply integrated with its suite of safety technologies. The Electronic Stability Control (ESC) module communicates directly with the EPS unit to provide corrective steering inputs during challenging driving conditions. For instance, if the system detects over-steer or under-steer, it can individually apply brake force and add steering assist to guide the vehicle back onto the intended path. This synergy between steering and stability control enhances driver confidence, particularly in adverse weather or emergency maneuvers.
Low-Speed Maneuverability and Park Assist
One of the most noticeable benefits of the electronic system is the enhanced low-speed maneuverability. The assist is calibrated to be light and responsive, making three-point turns and navigating tight parking garages feel significantly easier. This system is a perfect partner for the available Park View camera, which provides a top-down view of the vehicle and surrounding obstacles. The combination of visual guidance and light steering inputs reduces the effort required to parallel park or squeeze into a crowded space.
Common Issues and Maintenance
While the EPS design is generally reliable and requires less maintenance than hydraulic systems, specific issues can arise. Owners may occasionally encounter a stiff steering feel, a warning light on the dashboard, or unusual noises when turning. These symptoms often point to a failing electric motor, a problematic steering angle sensor, or wiring issues. Regular inspections of the steering system and prompt attention to warning signs are crucial to prevent a complete failure that could leave the vehicle difficult to steer.
Diagnostic Procedures
Diagnosing power steering problems in the 2015 Explorer typically requires a scan tool capable of interfacing with the vehicle's Body Control Module (BCM). Technicians can retrieve stored Diagnostic Trouble Codes (DTCs) that pinpoint the exact component or circuit at fault. Visual inspections focus on the wiring harnesses connecting the steering column, the motor unit, and the rack and pinion. A voltage test ensures the system is receiving the correct 12-volt supply, while checking for proper communication on the Controller Area Network (CAN) bus is also a standard step.
Performance and Driving Dynamics
The tuning of the power steering plays a vital role in the Explorer's driving character. Ford aimed for a balance that suits both daily commuting and weekend adventures. At highway speeds, the system provides a firm feel that inspires confidence and reduces driver fatigue. When navigating through city traffic, the effort is reduced to make frequent stops and starts comfortable. This intentional calibration ensures the vehicle feels planted and secure without sacrificing the natural feedback from the road surface.
