Active Suspension Systems: Diagnosing Electronic Shocks And Struts
We’ve all heard the term “Active Suspension,” but a shock or strut doesn’t really go anywhere – so what makes it “active?”
Understanding Steering Sensors
For these stability control and steering sensors to be accurate, most of them need to be calibrated on the vehicle, either with a scan tool, specific procedures or a short period of driving to be calibrated. If a sensor can’t be calibrated, the customer could be back with a malfunction indicator light on after a procedure as complex as an alignment or as routine as a battery replacement.
Hunting Down ‘Mysterious’ Steering Linkage Culprits
Steering system noise complaints can often be difficult to reproduce and diagnose. A squeaking noise in the steering column, for example, can often be influenced by temperature and humidity. In other cases, a squeaking noise can be caused by dry or corroded universal joints in the steering intermediate shaft located between the steering shaft and
Diagnosing Electrical Power Steering (EPS) Issues
Electric steering is a non-hydraulic system assisted by an electric motor operated by a software-driven power steering module.
Electronically Adjustable Dampener Diagnosis
Electronically adjustable shocks and struts use conventional mono-tube and twin-tube oil-filled dampeners. The rods, gas chambers and piston have the construction of passive units.
Electric Power Steering: Past, Present And Future – From Fieros To The Driverless Car
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.
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.
Service Advisor: Steered by Intelligence — Understanding Steering Sensors
The sensor’s basic function is to monitor the
driver’s steering inputs. This includes the angle of the steering wheel and/or the rate at which the driver is turning the wheel.
Undercover: Stopping Power — Servicing Ford’s Hybrid Braking System
In traditional vehicles, the energy used to decelerate the car is lost as heat when the driver applies the brakes. Hybrids, on the other hand, can recover a substantial portion of what would otherwise be “lost energy” and store it in the battery for later use. This is known as regenerative braking.
Component Connection: Breaking Down Power Steering Pump Diagnostics
Although installing a new or remanufactured replacement pump usually remedies the majority of power assist and noise complaints, a technician may still encounter a few complaints that appear to have no outward cause.
