Brake Job: 2010-2019 Ford Fiesta
The front brakes are the conventional single-piston floating caliper design.
Wheel Speed Sensor: Understanding ABS Brake Passive Sensors
The passive wheel speed sensor has been around a long time. It works quite differently than the active speed sensors that are found on most cars today. The passive speed sensor creates its own AC signal that changes frequency with wheel speed. This signal is only present while the wheel is turning at a rate fast enough to create the AC signal.
False ABS, ESC Activation Causes And Cures
The first mass-produced anti-lock braking systems (ABS) were introduced in 1985. By 2008, almost every passenger vehicle came standard with ABS. Next, electronic stability control (ESC) became a mandated safety feature for the 2012 model year. Along with all these advancements have come false activation complaints. Solving these has been a diagnostic conundrum through the years.
Electronic Proportioning Valve: Doing More With Less Hardware
Anti-lock brake systems (ABS) and the HCU are replacing proportioning, combination and other valves to change the braking forces in the front and rear. This is called Electronic Brake Distribution (EBD) and it can dynamically change the proportioning to take into account if the vehicle is turning or is loaded.
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.
Shocks and Struts: A Crucial Part of the Electronic Equation
When a vehicle’s ABS or stability control is really needed, how well it works is directly related to the tire’s contact patch. If the tire does not have traction, any type of electronic intervention or driving skill will not bring the car back under control. During a panic stop, weight transfers to the front tires,
