Anti-lock Brake System (ABS) Sensors

Technology such as anti-lock brakes (ABS) and electronic stability are now common place thanks to the ABS sensor or wheel speed sensor. A small device, it has a big role to play; monitoring the wheel’s speed and rotation to prevent the brakes from locking. So, it’s important to always fit an OE quality part - anything less could compromise the effectiveness of these safety critical systems. Featuring weather pack connectors and plated pins, and rigorously tested to OE standards, Delphi ABS sensors deliver optimum signal stability and reliability in all conditions, for an accurate, long-lasting sensor that you can fit with confidence.

Latest OE technology

Our ever-expanding range of ABS sensors features the latest digital signal technology. By creating a digital, square wave, Delphi magneto resistive and hall effect sensors only change frequency, not amplitude, improving accuracy, especially at lower speeds. They can also detect the direction of the wheels; forward, reverse and even stop. This is vital for hill hold control, autohold and automatic parking assistance technologies.

Protection from the elements

Given its position, the ABS sensor is particularly vulnerable to contamination from dirt and moisture. That’s why Delphi ABS sensors feature weather-pack connectors that lock out dirt, moisture, chemicals and other contaminants, coupled with plated pins for even great corrosion protection and improved conductivity.

Extreme testing

Water, heat and vibration can all affect a sensors characteristic. So we subject all our sensors to extensive thermal, shock and vibration testing just to be sure. With test temperatures ranging from -40 o C to 140 o C, we know they’ll perform even in the most challenging conditions. Delivering optimum stability and reliability at all times.

Easy installation

For right-fist-time fitment, Delphi ABS sensors are designed to match the OE. With like-for-like mounting and connector designs and wire lengths, technicians can fit quickly and easily, straight from the box.

The complete solution

As well as a growing range of ABS sensors, we also offer advanced diagnostic capability including the ability to read live fault codes and individual wheel speed data, essential repair data through our vehicle technical information package, and expert training and technical support.

Resource Highlights

The front camera on your Tesla 3, Y, S or X models is designed to enhance your driving experience.

As well as helping with parking, it improves navigation and takes in the wider view of what’s ahead, which in turn helps you better position your car on the road for a safer journey. That’s why it’s so important the camera is set up correctly.

In this step-by-step video from the experts at Delphi, you’ll learn how to properly calibrate the front camera of a Tesla. We cover everything from:

• Camera angle pitches
• Driver assisted systems (DAS)
• The equipment needed to carry out a successful calibration


What equipment do I need to calibrate the front camera on a Tesla?

We used Delphi’s Advanced Driver Assistance Systems (ADAS) calibration solution, the CRC 150 rig and target board TFC-5.

What is a Tesla DAS system?

Tesla have different categories of cameras and radar systems they call these DAS systems. DAS stands for driver assistant systems, and we group these into three categories – DAS 1 has a single camera in the front windscreen, DAS 2, 2.5 and 3 have three cameras in the windscreen, and DAS 4 has two cameras in the front windscreen.

In what order do you calibrate the camera?

Carry out the work in two sections. Firstly, check the pitch verification to ensure the camera angle is right. Then do a dynamic calibration on the road.

How long do I need to drive the car for the dynamic calibration?

You need to drive the car ideally in a range from 30-50mph, but up to 60mph, and Tesla say it can take up to 100 miles for the camera to perform its calibration. The display on the dash keeps you up to speed with the process of the calibration.
