Electric Power Steering Evolution
Diagnosing electric power steering systems requires an understanding of voltage, current and loads.
EPS Steering Assist
Modern electric power steering (EPS) steering gears are inextricably linked with body and chassis control electronics, which is a very good reason for an alignment technician to develop a working relationship with a modern, enhanced scan tool.
Diagnosing Electric Power Steering (EPS) Issues
If you’re an import specialist, it’s important to know that, although electric power steering (EPS) has been introduced on many 2004-and-later domestic applications, EPS recently began appearing on popular import nameplates like the 2015 Honda S2000 and 2014 and 2015 models of Toyota RAV4, Camry and Highlander.
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.
Electric Power Steering: Mating Electrical And Mechanical Diagnostics
Most electric power steering system modules are on the high-speed CAN network with the engine control, ABS and transmission control modules. Some vehicles will also include the body control module and other modules that are critical to the safety of the vehicle. These modules share a lot of data to make sure the driver does not notice when the electric power steering is working.
Electric Power Steering Advancements
Electric power assist does more than add force in either direction; it can push back to improve handling and driver comfort. These corrections could be as innocuous as adding a little assist for road crown, or as obvious as the vehicle steering on its own. But, a lot of the improvements in electric power steering have mostly gone unnoticed by the driver and even the technician.

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.
2011-2015 Chevy Cruze Alignment: Are You Calibrating The Steering Angle Sensor?
The Chevy Cruze debuted as the replacement for the Cobalt. On the outside and under the hood, the Cruze is a big upgrade from the Cobalt. Underneath, however, the two cars have similar setups. In the six years, the Cruze has been on the road, it has proven to be a reliable vehicle for the most part, but it has had some suspension issues.
Steering Angle FAQs To Help Boost Your ABS & Stability Control Diagnostics
Chances are you will never crack open a steering angle sensor (SAS) cluster to repair it. But, this sensor should not be a mystery. To be effective at ABS and stability control diagnostics, knowing how sensors measure angles and information is critical.
