Understanding Advanced Driver Assistance Systems (ADAS)

A key part of being able to diagnose a problem with advanced driver assistance systems (ADAS) is understanding how the system works. Knowing what is happening inside the system will help you properly diagnose why the system may be failing. This will prevent replacing parts that are not causing the system issue. Let’s take a look at what we learned with this series of articles.

The different cameras and sensors (inputs) that communicate with ADAS are located on almost all sides of the vehicle. Many of the inputs have multiple functions, and talk to more than one system. This means that if one of the inputs fails, it might influence more than one system.

The inputs can communicate with many modules in the vehicle. Depending how the vehicle is equipped, the ADAS can take over and control many different functions of the vehicle. This includes some drivability functions, like braking and steering.

Understanding how the systems function can shorten diagnostic times. Knowing what part of the system to test will help prevent installing parts that don’t actually fix the problem.
