Key Features & Benefits

This little guy – it's an Electronic Control Unit, specifically for your Electric Power Steering. It basically manages everything related to how much assistance you get when you turn the wheel. It’s reading signals from sensors – things like vehicle speed, how far you’ve turned the wheel, and even how much force you’re putting on it. Then, it uses that info to tell the power steering motor exactly how much help to give you. It’s handling a lot of calculations very quickly to make steering feel just right at all speeds. Think of it as the brain behind your power steering system. The steering rack does the actual work of turning the wheels, but this unit is telling it how and when. It’s not just about making the steering lighter; it adjusts based on your speed. At low speeds, like parking, it gives you a lot of assistance. On the highway, it firms things up so you have better control and feel the road. It's a pretty critical component to a modern steering setup.

Symptoms, Risks & Replacements

If this unit fails, you’ll likely notice a big change in your steering. It could become very heavy, making it difficult to steer, especially at lower speeds. Or, it could become erratic or jerky. Basically, you lose that smooth, consistent steering feel you’re used to. It’s a safety item – you need reliable steering to control the vehicle.
