Hydraulic Control Module Diagnostics

Tomorrow's Technician

ESC systems add software and sensors like yaw, steering angle and even throttle control to keep the vehicle under control. This will release or bleed off the hydraulic pressure that is holding the wheel. When the ABS activates, the pulsing of pressure can create a hydraulic jackhammer. ABS is the foundation of the ESC system.

Electric Power Steering Evolution

Tomorrow's Technician

In the late 1980s, many cars now had wide front tires and it was difficult to route hydraulic lines from the engine bay to the front of the vehicle and the rack. Many of the first systems were electro-hydraulic with a electric motor powering a hydraulic pump. The software also regulates the temperature of the motor.

LUBRICATING HYDRAULIC FLUID Instead of a linkage connected to a shifter, the shift forks are actuated by hydraulic solenoids. The shifting behavior can be fine-tuned by software that allows very different characteristics using the same DSG transmission. The fluid also acts as a hydraulic fluid.

Brake Pad Diagnostics

Brake & Front End

To correct this kind of wear, take the same steps as fixing outer pad wear as well as inspect the hydraulic brake system and caliper for residual pressure and guide pin hole or piston boot for damage, respectively. If the caliper is a two-piston floating design, the pad can become bent and eventually cause a hydraulic failure.
