GM Calibration Requirements – Information now available on I-CAR’s RTS portal.

| November 29, 2017

Today’s GM vehicles offer their latest in safety features, including lane departure warnings, park-assist, and blind spot detection. As more vehicle materials, technologies and safety procedures are introduced, collision repair technicians need to be equipped with the necessary knowledge and skills to perform complete, safe and quality repairs.

These interrelated safety devices are known collectively as Advanced Driver Assistance Systems, or ADAS. The presence of these systems means that, after an accident, repair professionals should conduct a pre-scan, a post-scan and a post-repair calibration/aiming procedure to help ensure the vehicle’s cameras and sensors are accurately aligned. Failing to perform the original equipment
manufacturer (OEM) ADAS calibration procedures can compromise complete, safe and quality repairs.

ADAS systems involve specific calibration (aiming) requirements for each camera or sensor that may differ for each vehicle model. Procedures to precisely aim cameras and sensors that have been removed and installed (R&I) or replaced go beyond post-scanning. In an effort to better educate network technicians needing assistance in recalibrating vehicles, I-CAR has worked in collaboration with GM to offer up-to-date GM vehicle calibration requirements through I-CAR’s Repairability Technical Support® Portal (RTS).

The calibration event requirements for 2016 and, soon, 2017 vehicles can be found through the I-CAR RTS Portal, where I-CAR has created an OEM Calibration Requirements Search feature. This web-based tool describes conditions under which calibration is required when repairing vehicles with ADAS to ensure the repair is done properly, and to help reduce the time needed for developing the repair plan.

However, access to the OEM repair information is required to perform any of the required calibrations. The OEM Calibration Requirements Search tool is accessible to any industry professional
who has access to the RTS Portal. This includes I-CAR Gold Class® shops, I-CAR Platinum™ individuals, I-CAR volunteers and instructors, I-CAR members, professionals who train with I-CAR on a regular basis, and daily or yearly subscribers to the website.

This search feature allows you to select the make, model and year of the vehicle being repaired. Under each vehicle, you’ll find many of the possible options for that vehicle and the specific events that will require a calibration. You will see which cameras and sensors relate to each system and the locations of these components. Information on whether you’ll need specific scan tools or special tools to make the calibrations is also included. In addition, the listings indicate whether the system automatically lights a malfunction indicator lamp (MIL) or sets a diagnostic trouble code (DTC) if it detects either an error or an incomplete calibration.

In the 2016 Chevrolet Silverado, for example, the camera near the rearview mirror is imperative for the Lane Keep Assist feature to function properly. The portal indicates that a DTC will set if there is an issue in the system. For proper calibration, a scan tool is required.

Calibration is needed following a wide range of repairs. Here are two examples of repairs requiring calibration:
• The camera module is replaced • The windshield is replaced

Through the I-CAR RTS Portal, collision repair professionals can further access videos on navigating GM’s collision repair websites, articles on GM vehicles, GM glass replacement requirements and a number of other pertinent search features such as partial parts replacement, restraint system part replacement requirements, and hybrid and electric vehicle disable information.

I-CAR also offers newly released courses on calibrations for front-facing cameras, diagnostics and scan tools, and vehicle technology trends for 2017.

I-CAR also recently published two Collision Repair News articles, available on the I-CAR RTS Portal, that discuss new and additional calibration requirements for GM vehicles (links to the articles follow):
