You probably won’t encounter many certification test questions about Advanced Driver Assistance Systems (known as ADAS), but you should understand how these systems affect repairs when entering the real-world.
In a new episode of Tech Test Prep, Carley Millhone shares some tips for working on vehicles with ADAS systems. Sponsored by Blue Streak by Standard.

Using a scan tool to communicate with different modules can confirm operation and the source of communication codes.
Scan tools have come a long way in the past decade, such that improvements in sample rates and display capabilities can give technicians vital insights into multiple areas under a vehicle like wheel speed sensors, ride height sensors and oxygen sensors.
A modern scan tool can graph the output of multiple data PIDs on a test drive, which is how the control module sees and interprets the data. For example, if you see sudden drops in speed from a wheel speed sensor, it is a sign that the air gap between the encoder ring and sensor has changed due to “play” inside the bearing. This can point you in the right diagnostic direction and help you focus on one corner or system of the vehicle.

Here’s how oil can influence carbon deposits.
The following is an example of a dishonest vehicle and how to go about catching it in its lie.
If the suspension bottoms out, contact between the piston and the bottom of the tube could occur.
