The list is displayed on the diagnostic tool and user input is received on the diagnostic tool identifying a selected ADAS sensor from the list. Calibration instructions associated with the selected ADAS sensor are displayed in response to receiving the user input. An image is projected onto a projection surface adjacent the vehicle, with the projected image being associated with calibrating the selected ADAS sensor. Computer executable instructions are executed on the diagnostic tool to autonomously calibrate the selected ADAS sensor using the projected image in response to receipt of the user input and projecting the image onto the projection surface. ## Claims ### Claim 1 A method of calibrating an Advanced Driver Assistance System (ADAS) sensor on a vehicle, the method comprising the steps of: a) receiving a signal at a handheld vehicle diagnostic tool from an onboard vehicle computer, the signal including a list of ADAS sensors located on the vehicle;
