Technicians should be aware of what’s required to keep advanced driver assistance systems (ADAS) running safely after a collision. Whether that be aiming a camera, which can cause a system to not function as intended, or checking for diagnostic trouble codes (DTCs). For a basic understanding of what’s required, we’ve put together a series of articles that provide general information on what’s required to repair the system after a collision. Let’s take a look at steering angle/position sensors.
Steering angle/position sensors are normally part of the steering column. The sensor monitors what direction the steering wheel is turned. The steering angle sensor controls systems such as, lane keep assist, blind spot detection, and adaptive lighting. Calibration of a steering angle sensors may be needed after an airbag deployment, structural repairs, or a wheel alignment.
Calibration is normally done with a scan tool. Sometimes the vehicle will need to be on an alignment rack. The calibration process is normally done by putting the wheels in the straight forward position, and then zeroing out the sensor with a scan tool.
Being informed on these systems is important to a complete, safe, and quality repair. Many consumers are purchasing a certain vehicle specifically for these driver assistance features. The consumer knows the system is on their vehicle and they are relying on it to help keep them safe. Therefore, technicians also need to be aware when driver assistance systems exist and have the knowledge to properly repair the system.
