Unlike traditional hydraulic power steering systems, EPS utilizes electric motors and electronic control units to assist the driver in steering the vehicle. Electric power steering systems are designed to be more energy-efficient compared to their hydraulic counterparts.
While servicing wheels and tires may seem purely mechanical, the role of sensors and electronic systems that monitor tire pressure and wheel speed has grown significantly. Cybersecurity is crucial to protect the integrity of the communication between these sensors and the vehicle’s electronic control units (ECUs).
Electronic Differentials Some automakers are using the ABS system to control the differences in speed of the wheels on an axle. The torque-vectoring differentials can control the amount of power going to each wheel connected to the axle using hydraulics or electric solenoids. These can be found on performance cars and off-road trucks.
Power steering is now offered in a few different ways; hydraulic, electrical, and more recently, drive-by-wire. Types of Power Steering Power steering is either hydraulic, electronic, or electro-hydraulic. Pros and Cons Of Hydraulic Power Steering Hydraulic power steering has been around for a long time.
The brake hydraulic control module on these vehicles has at least 12 valves. These differentials can act like a locking, limited-slip or open differential with only a change of the electronically controlled clutches. These changes helped reduce cost while making the system more reliable.

Where It Started: Hydraulic ARBs ARBs were introduced in the mid-to-late 1990s in some European vehicles. Hydraulic ARBs use hydraulic fluid to apply torsional force against the roll bar ( Figure 2 ). This is similar in principle to how hydraulic power steering systems apply force to the steering gear to provide steering assist.
The concept of using a torque converter, oil pump, planetary gear sets, clutches, bands and a computer-controlled hydraulic valve body to transmit torque and to change gear ratios is relatively simple. The difference between the speeds of the impellor and turbine is called stall speed.
Manufactured by South Korean supplier Mando, the suspect parts in question are referred to as ABS module by Hyundai and HECU by Kia, HECU as in hydraulicelectronic control unit. Given the number of vehicles and recalls, the Office of Defects Investigation has opened an audit. continue reading. )
To correct this kind of wear, take the same steps as fixing outer pad wear as well as inspecting the hydraulic brake system and the caliper for residual pressure and guide pin hole or piston boot damage, respectively. If the caliper is a two-piston floating design, the pad can become bent and even cause a hydraulic failure.
Some hybrid systems apply the hydraulic brakes at lower speeds. Normally, the fluid pressure for the wheel hydraulics is generated by the pump and/or accumulator in the ABS HCU or a stroke simulator, and is regulated by the teamed efforts of the ABS and the PCM’s logic.
It controls fluid flow for smooth gear shifts and works with solenoids , sensors, and hydraulic circuits to automate shifting. Type of valve body : Your vehicle may have an electronic or hydraulic valve body, which can impact the price.

If the voltage does not drop or the circuit has a short or open, the module will deactivate the circuit to preserve the electronic components inside the module or sensor. For most wheel speed sensor circuits, when the ABS hydraulic control unit (HCU) wakes, it sends out a bias voltage signal to test the wheel speed sensor circuits.

In this video, let’s discuss these new technologies and what ABS (anti-lock braking systems) and ESC (electronic stability control) have to do with ADAS performance. Both systems use the ABS hydraulic control unit (HCU), which consists of an electronic module, hydraulic modulator, and pump.
Bushings: The MINI uses four hydraulic bushings. In the front, the hydraulic bushing is located at the rear of the control arms. In the rear, the hydraulic bushing mounts the trailing arm to the body. Steering Angle Sensor (SAS): On MINIs without Electronic Stability Control (ESC or DSC), SAS is not installed.
Seals, air lines and electronic components are also subject to wear and tear. Today there are traditional air systems as well as air-over-magnetic and air-over-hydraulic. Rubber air chambers deteriorate in the harsh environments under a vehicle and must be replaced. These systems vary greatly.
And while that derailleur might be controlled by cables, hydraulics or even electronics, it’s usually down to you to set it in the right place. If you’ve got a bike , there’s a good chance it’s set up with a derailleur at the rear and a bunch of gears to help you cycle more efficiently. However, there was once a push… Read more.
Shifting is controlled by the DCT electronics/hydraulic module on the side of the transmission. The computer is trying to strike a balance between smooth shifts and clutch longevity. The transmission module works with the engine control module to manage torque coming from the engine during launches and shifts.

Low Transmission Fluid Your automatic transmission relies on hydraulic fluid pressure to operate. In a modern, electronically controlled automatic transmission, shift solenoids control the flow of transmission fluid. In older non-electronically controlled transmissions, shifting was controlled by shift valves, but the idea is the same.
Whenever any conditions change within the hydraulic circuit, such as the valve body or solenoids, adjustments to the system may be necessary. Figure 2 Electronic control over the entire pressure range of the transmission means that the TCM can ramp the rise and drop of pressure to specific clutches and brakes to achieve a smooth shift.
This is especially true on vehicles with ABS and electronic stability control, because if you don’t get it right, well, actual cavitation will occur inside the hydraulic control unit for the ABS. So make sure you’re checking that service information to what kind of fluid it requires. And when this happens, you get tiny little bubbles.
As a diesel mechanic apprentice, gaining a deeper understanding of diesel engine components, electronic systems, and hydraulics is paramount. Mastering Technical Proficiency and Adapting to Industry Advancements After Diesel Mechanic Training Central to a successful apprenticeship is the relentless pursuit of technical excellence.
At the master cylinder on some vehicles, there might be a quick-take-up valve in the replenish port to hydraulically pull the caliper piston back from the rotor. Some vehicles are even using the valves in the ABS module to electronically retract the pistons.

As electronic power steering (EPS) continues to grow as a segment of the power steering industry, drivers will inevitably need to bring their vehicles in for service from time to time.
The parking brake and hydraulics are where you’ll find any service issues. ABS Assist The Ridgeline has electronic brake distribution and brake assist. Aside from the general proportions, the Ridgeline is a different vehicle made in a different plant. Parking Brakes The parking brake on the Ridgeline is actuated using a pedal.
The exception to this rule is vehicles with electronic brake distribution. This will release or bleed off the hydraulic pressure that is holding the wheel. Inside are the valves and solenoids that control the pressures to the wheel. During normal operation, the pressure from the master cylinder goes through the HCU unaltered.
Second, it must be able to stop a vehicle under a specific distance if the hydraulic brakes have failed. Electronic Parking Brake A growing number of vehicles are equipped with electronic parking brakes that automatically engage the parking brake when the transmission is shifted into park.

Figure 4 ESP and ETS All 4MATIC systems use an Electronic Traction System (ETS) and an Electronic Stability Program (ESP). The hydraulic control module on a 4MATIC has at least 12 valves. This is thanks in part to the removal of the gear stage for the transfer case’s power take-off (PTO), as well as an optimized oiling system.
The days are gone when transmissions were purely mechanical and hydraulic and all you really needed was a set of high-pressure gauges to check line pressure and a vacuum gauge to check the engine’s intake vacuum and the integrity of the vacuum modulator.
You can purchase a new guide at autolift.org and there is even an electronic version you can use on your phone, tablet, or computer. Once you have the vehicle at the appropriate service height, be sure to relieve the hydraulic pressure by lowering it onto its mechanical locks before getting to work.
