GM Tech Tip: Electronic Power Steering Gear Leaks
On GM vehicles with electric power steering starting in 2009, you may see grease or sealant on certain locations of the steering gear.
Electronic Power Steering: More Common Than Uncommon
Electric power steering (EPS) is coming to your shop on a lot more cars and trucks ranging from the Chevy Cobalt to the latest Ford F-150. So, there is no avoiding EPS diagnostics or repair. Most EPS setups are more than the rack and motor; they are a highly connected system that rivals any engine when it comes to diagnostics.
CARDONE Meets Aftermarket Electronic Power Steering Demand
Fuel efficiency was a primary driving force behind the market shift from hydraulic to electric power steering nearly a decade ago. Anticipating the growth in demand, CARDONE launched EPS in 2016 with the Ford Fusion, which remains the top seller.
Electronic Power Steering: More Than Just An Assist
Electric power steering is quickly becoming a standard feature on new vehicles, but it’s not an emerging technology. It’s been in the field for the better part of two decades. Now, electric power steering has continued to advance by making autonomous safety features possible.
Electronic Power Steering: Better Than Hydraulic?
Diagnosing electric power steering systems requires an understanding of voltage, current and loads. Also, a technician must understand how the modules and sensors work together to determine the level of assist.
GM Tech Tip: Grease Or Sealant Visible On Electronic Power Steering Gear Is Not A Leak
On GM vehicles with electric power steering starting in 2009, you may see grease or sealant on certain locations of the steering gear. Vehicles with electric power steering systems do not have fluid inside of them.
Electronic Power Steering: A Change In Technology
An Electronic Power Steering (EPS) system’s advantage over a hydraulic system is if the engine stalls, you will still have steering assist. This advantage can also be a disadvantage if the system should shut down while the engine is running because if the engine stalls, you lose steering assist. A driver unaware of this condition
Steering Angle Sensor Operations
It is important for the ABS/ESC module to receive two signals to verify the steering wheel’s position.
Steering Angle Sensor 101
The steering angle is used by many ADAS functions, from blind-spot detection to autonomous driving.
Diagnosing Steering Concerns Requires Proper Service Methods
Without correct tools it is impossible to do proper systematic diagnostics. Sponsored by The Group Training Academy.
