Hydraulic systems are behind some of the most essential functions in automotive repair, whether lifting a vehicle in the shop or bringing a car to a stop on the highway. Thats why hydraulic training is a key part of becoming a professional technician. As cars have evolved, so have the systems that power them.
If you have ever driven a car or truck with a fully locked differential around a tight corner or tried to get a car with an open differential out of a snowbank, you know about the benefits of a limited-slip differential. These can be found on performance cars and off-road trucks. The two wheels are connected using spider gears.
The brake hydraulic control module on these vehicles has at least 12 valves. If the car or truck is accelerating hard from a stop, the ETS will apply the brakes independently to prevent slipping. These differentials can act like a locking, limited-slip or open differential with only a change of the electronically controlled clutches.
Power steering is now offered in a few different ways; hydraulic, electrical, and more recently, drive-by-wire. Continue reading to learn more about power steering, its history, reliability and repairs, and how each type impacts the driving dynamics of a car. Hydraulic steering is not without flaws though.
These systems can optimize the air springs and adjustable valving in the hydraulic dampener to give the best ride while not compromising handling and safety. When the car is first started, observe whether the self-checks happen. Most air ride and chassis codes are set in the first minute after the car is started.
If your cars gear shifts feel rougher than your Monday mornings, a failing transmission valve body could be the culprit. This covers: Parts cost: $100 to $2,500 Labor cost : $300 to $1,000 NOTE: Only automatic transmission cars have a valve body. Use jack stands to safely raise the car for access to the transmission.
Malfunctioning electronic control unit (ECU): If the ECU fails due to an electrical issue like low voltage, the electronic parking brake system won’t engage efficiently. Faulty sensors: The electronic parking brake relies on sensors to monitor brake engagement, position, and hydraulic pressure.
With regenerative braking, instead of just wasting that energy by releasing it into the air, the vehicle captures it and saves it in a box in the back of the car as stored energy. Later, that stored energy will be converted back into kinetic energy and poured back into the operation of the car.
Is your car not shifting gears like it used to? When an automatic transmission equipped car won’t shift gears, there could be several potential issues. Below is technical expertise on “Why is my automatic car not shifting gears?” But that convenience comes at the price of complexity.

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.
I had a 1998 E320 4MATIC wagon, and I absolutely loved that car in the winter. 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. I can attest to this myself.
Is your car making strange buzzing noises while turning ? Ignoring it will not only make your car rides unsteady but also lead to costly repairs down the line. Mechanical problems : Though the EPS system is mostly electronic, it still depends on mechanical components like the steering rack and pinion.
Second, it must be able to stop a vehicle under a specific distance if the hydraulic brakes have failed. The typical sign of a worn hinge pivot is normal travel on the lever or pedal, but the parking brake will not hold the car on a hill. The parking or emergency brake has to perform two distinct jobs.

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. When you first pull the car into the bay, the basic rules of spotting the vehicle remain the same. If possible, leave the car in neutral so it can be rolled to help position the lift pads on some EVs.
If your car won’t reverse but will go forward just fine, you’re not alone. In this post, we’ll dive into the 10 most common reasons your car refuses to reverse but moves forward. Will I Need a New Transmission If My Car Won’t Reverse? Can a Faulty Speed Sensor Cause My Car to Not Reverse? What’s worse?
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.
The first reaction is often, “We don’t do that type of work” — when, in reality, there is real profit in performing drivetrain diagnostics and “in-the-car” repairs. But with today’s electronic controls, you need to use a scan tool, scope and a multimeter.

The level system control module mounted in the trunk connects to the Sensor Electronic Control Module using a FlexRay data bus. It measures acceleration and movement of the car along the x, y and z axis, other information from the ABS hydraulic control unit and the ride height sensors at all four wheels.

That’s your car telling you it’s in trouble, and if you keep going, things can go downhill fast. Slipping gears: If your vehicle shifts unpredictably or feels like it’s struggling to stay in gear, the transmission system could be overheating and losing hydraulic pressure. Seeing a “ transmission too hot ” warning while driving?
As such, they play a vital role in enabling your car to move, accelerate and decelerate safely. Essentially, it’s comprised of gears, shafts, hydraulic systems, and electronic components. Essentially, it’s comprised of gears, shafts, hydraulic systems, and electronic components.
Faulty transmission shift solenoids lead to delayed gear shifting, skipping gears, and gears getting stuck — making your car dangerous to drive. This helps in gear lubrication and operation on automatic transmission vehicles (manual transmission cars don’t have transmission solenoids). How does it work?
Bushings Hydraulic bushings have chambers and valves to help absorb vibration and change the angles under certain conditions. These springs need to be correctly oriented so they can work properly when the car is going straight and when the wheel is turned. Active Suspension Look for more electronically controlled shocks and struts.

This alert could point to issues with your brake booster, 12V battery, or electronic braking system, especially if you drive a hybrid or EV. In this guide, we’ll break down what this warning means, what causes it, and how to safely get your car back on the road. What Are the Possible Malfunctions Behind Low Braking Power?
Electronic stability control (ESC) also went by another name when it was first introduced – roll-over mitigation. Both ABS and ESC use the same module to carry out corrections, the ABS hydraulic control module, or HCU. This module has three parts: the electronic module, hydraulic modulator and pump.
