While many have noticed that advanced driver assistance systems (ADAS), are showing up on vehicles, there still is confusion on what is required of these systems after a collision occurs. The Ask I-CAR team frequently get questions in regard to calibration of ADAS. Many of these questions can be answered simply by searching the OEM Calibration Requirements Search. However, there are some questions that may need more details than the calibration search provides. Let’s take a look at the 2019 Jeep Grand Cherokee ADAS.
For 2019, the Grand Cherokee comes standard equipped with blind spot detection, rear cross traffic, park assist, and rear view. Additional optional systems include active park assist, adaptive cruise control, collision warning, and lane departure warning. This means that there is a large array of cameras and sensors that collision repairers will need to be aware of, many of which will require calibrations. Information for when these calibrations are required can be found in the vehicle specific repair information, and also on the 2019 Grand Cherokee OEM Calibration Requirements Search page.
The first sensor you will notice is the front radar sensor. It is easy to recognize because it is an exposed radar, meaning that is not hidden behind the bumper. Located in the lower grille, in the center, the dark rounded shape bubble is the sensor. This sensor gives information to systems such as adaptive cruise control and collision warning. There are several events that will require calibration for this sensor.
Next there are 6 ultrasonic sensors going across the front bumper cover and an additional 4 ultrasonic sensors in the rear bumper. These sensors report to the park assist and active park assist system. These sensors do not require calibration.
Located in the interior of the vehicle, in front of the rearview mirror is the forward-facing camera. This camera sends data to the lane departure warning and collision warning systems. Calibration is required for this camera according to the events listed in the repair manual.
Behind the rear bumper cover are two radar sensors. There is one on each side of the bumper cover, and are used by the blind spot detection and rear cross traffic systems. Calibration is not required for these sensors, however, there is a Proxy Configuration Alignment.
Finally, there is a camera located in the center bezel on the rear liftgate. This camera is for the rear view system. This camera will not require calibration.
