Tech Feature: Solving Steering Wander
As frustrating as diagnosing steering wander complaints might be, most can be solved by thoroughly inspecting the physical condition of the vehicle. In the following text, I’ll cover some of the most common causes of steering wander and how to detect them during an undercar inspection.
Wheel Speed Sensors: ABS and TCS Signal Use
The signals from the Wheel Speed Sensors (WSS) are the most important sensor input to the Brake Control Module (BCM) for ABS activation.
Selling Services: Wheel Speed Sensors
There are two main types of magnetic wheel speed sensors — passive and active. Both use a tone ring to reference against and each look very similar to one another.
Tech Tip: Steering Position and Yaw
The Electronic Stability Control (ESC) program uses the Anti-Lock Brake System (ABS) and Electronic Throttle Control (ETC) to maintain vehicle stability in a cornering maneuver. The ESC program requires the communication between the Engine Control Module (ECM) and ABS controller. This communication takes place on the Controlled Area Network (CAN) buss of the vehicle. The program uses input from the following sensors: steering wheel position, throttle pedal position, throttle position, engine speed, brake switch, wheel speed, yaw and ….
Steering Position and Yaw
Driving skills and Electronic Stability Control One of the first things a novice driver asks is: “Do I turn into the skid or away from it?” With Electronic Stability Control, this decision is made for us. When a vehicle begins to skid during a cornering maneuver, the skilled driver steers into the direction of the
Tech Feature: The Future of Steering
The Steering System on light vehicles is one of the most critical interfaces between the road, vehicle and driver. The nature of this interface has remained virtually the same for most of the life of the automobile. Somewhere early one it was decided to upgrade the old "tiller" steering system with the traditional wheel. With all the activity in the industry that challenges the assumptions of current vehicle systems what is the future for steering systems?

Tech Tip: Replacing Wheel Bearing Hubs Equipped with Wheel Speed Sensors
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside world.

Electric Power Steering
When a technology like hydraulic power steering has been around for so long, it is difficult for technicians and even the training establishment to deal with a new system like electric power steering. These systems abandon fluid logic for electronic logic. It is not a simple exchange of power steering fluid for magnetism. Wrapping one’s
