Electronic Parking Brake Deactivation Procedures On Ford Vehicles
Putting the system into service or maintenance mode to retract the pistons is performed using a series of steps while sitting in the driver’s seat.
Variable Assist Power Steering Diagnostics
During the past 20 years, steering feel is one of the most researched and engineered aspects of any vehicle. To get the feel just right, OEMs are using a combination of old and new technologies that can also help to make the engine more efficient.
Electronically Adjustable Dampener Diagnosis
Modern suspension systems can read the road and the driver’s intentions to help select the correct amount of dampening force. These systems see the vehicle dynamics through accelerometers and Hall-effect sensors, and they can change settings in milliseconds. Some can even detect potholes and dial up the rebound so the wheel does not drop to the bottom.
Making Sense Of Steering Angle Sensor Input And Data
Measuring the position angle, rate of turn and force of the steering wheel is critical for Electronic Stability Control (ESC) systems. Scan tools call these Steering Angle Sensors (SAS) and typically display the information in degrees.
Steering System Calibrations
We all know that the evolution of technology in our ever-changing automotive industry translates to many gray areas when it comes to servicing new vehicle systems using updated service procedures and tools. Steering angle sensor calibration is one of those gray areas.
Power Steering Dynamics And Diagnostics
Twenty-five years ago, when the power steering failed, diagnosing the system was easy. The most difficult problem to diagnose was the “morning sickness” that plagued some vehicles when they were cold. Today, the introduction of speed sensitive steering, electric power steering and computer controls have made power steering diagnostics more demanding.
Electric Power Steering Diagnostics
Electric power steering is more energy efficient than hydraulic systems and does not provide assist until it receives driver input, but there are differences in the hydraulic and electric assist that will affect the driver’s and technician’s understanding of the component and its integration into the ESC and self-park system.
Autoliv And Neonode To Showcase The Future Of Steering Wheel Technology At CES
Autoliv Inc., a global leader in automotive safety, and Neonode Inc., the optical touch technology company, announced they will jointly showcase the next generation of automotive human machine interface at the Consumer Electronics Show (CES) in Las Vegas. To date, the joint development has focused on accelerating the development of the next generation of driver
Electric Power Steering: Past, Present and Future
Electric power steering is fast becoming a standard feature on new vehicles, but it’s not an emerging technology, as it’s been in the field for the better part of two decades. One of the first domestic applications that almost made it to production was the Pontiac Fiero. The 1989 model was going to have an
Servicing The Electronically Adjustable Shocks Of Full-Sized GM Trucks
Since the 2000 model year, GM has offered electronically adjustable suspension as an option on Chevy, Cadillac and GMC full-size trucks. The system actuates the valving in the shocks to control suspension position and body attitude. The electronic suspension control (ESC) system independently controls each of the four shock absorbers in order to control the
