General Motors (GM) recently published a guide for auto glass businesses, auto insurers and consumers on Advanced Driver Assistance Systems (ADAS). The recently published document provides a list of available systems, components involved, and when these require a calibration procedure be performed.
“During the course of vehicle diagnosis and repair, part replacement, or collision repair, components related to Advanced Driver Assistance Systems may need to be accessed or removed,” a portion of GM’s post reads. “In some cases, a calibration may need to be performed after service to ensure proper operation of the system.”
GM advises industry members to refer to the “appropriate service information document for specific calibration instructions, as well as any additional programming operations needed if the component was replaced.” The guide specifies the official name, abbreviation and “regular production option” (RPO) code of each ADAS feature. It also explains when calibration would be required and the cause of calibration issues for certain parts.
For front-view windshield cameras GM states calibration is required if: the windshield was replaced removed or reinstalled, it were removed from the bracket and reinstalled, and there was collision repair or airbag deployment.
“SPS programming is required after replacement. Some vehicles will immediately begin calibration after programming, others may require calibration to be started using GDS2. Refer to Service Information for specific programming and calibration instructions after replacement,” a portion of GM’s post, in the section related to front-view windshield cameras reads.
According to GM, if the front-view windshield camera is slow to calibrate or if the calibration will not complete, you should make sure the vehicle is being driven in an area conducive to calibration. An ideal calibration environment, according to GM, is a two-lane divide highway with lane makings on both side of the lane, driving the vehicle between 35-56 miles per hour. The auto manufacturer notes that any of the following conditions may increase the length of time require to complete calibration or result in an inability to complete calibration:
- Heavy traffic;
- Stop and go traffic;
- Mountain roads;
- Curves in the roadway;
- No or poor lane markings;
- Botts Dots-type lane markings;
- Dirty windshield glass;
- Operating the vehicle outside of the 35-56 miles per hour range;
- Driving in adverse weather, such as snow, fog, or extreme rain, or driving directly into the sun;
- Cracked or damaged windshield;
- Vehicle add-on equipment that blocks the front-view windshield camera, such as a windshield tint strip or vinyl banner, or equipment that blocks the view of the road, such as bug deflectors or grill guards; and
- Windshield not properly centered in the windshield opening
