HellaGutmann CSC Tool


Cameras and sensors dedicated to driver assistance systems need calibrations and initializations made in absolute safety. A diagnostic accessory from HellaGutmann Solutions allows to control and calibrate the Adas of 28 different brands

As the number of vehicles equipped with advanced driver assistance systems (Adas) keeps rising, the need for suitable calibration systems grows as well. After replacing the radar, for example, but also after repairing or replacing the bracket that supports it or the area surrounding the sensor. Or, even after a slight change in the vehicle’s set up. On the other hand, it may be the on-board computer that signals the need for a calibration because it has detected excessive tolerances in the measuring range.


A Babel of systems

Each manufacturer supports an Adas system with his very own system and, consequently, the calibration procedures change; some manufacturers have even gone as far as changing the modular architecture of Adas systems as car models have been renewed or replaced. The proper functioning of safety devices such as adaptive cruise control or emergency braking systems is essential and no mistakes are allowed. The high inter-connection between the systems always requires complete initialization and calibration, without which one cannot be sure that the system is able to measures, and decide, with infinitesimal error margins. Incorrect reading ​​could in fact prompt the systems to intervene with bad timing, with obvious consequences. On board we find cameras, long distance radars (with a measuring range of 250 meters) and short distance radars (60 meters). Long distance radar calibration is particularly delicate because a slight shift in the position of the radar head or the camera in relation to the geometric axle can cause the system to deliver incorrect results, a small error in the angle of the vehicle axis translates into a very large error. The calibration requirements of these systems find the perfect answer in the new CSC Tool by HellaGutmann Solutions, whose first model was launched back in 2014. This tool, with an acronym that stands for Camera and Sensor Calibration, offers nine calibration modules dedicated to the safety systems on a great number of vehicles, regardless the manufacturer. It guarantees a high degree of accuracy thanks to the ability to orient the control markings in relation to the rear axle of the vehicle. In the new version there is also a wheel support control for the rear suspension system check; other accessories are a metre with clips for precision measurement of the distance of the calibration panels (optical targets) from the car and their centring in relation to the vehicle axis, and a box in which the calibration panel can be placed when not in use. The CSC-Tool fully-integrates with Mega Macs diagnostic tools and provides accurate results with no need for a fully-equipped axle alignment station. This allows the specialist to work on systems that receive a signal directly from a radar (such as an adaptive cruise control) as well as on camera-based systems such as lane departure or road signal recognition.


Modular system, wide coverage

The CSC tool allows a workshop to work with ease on cameras found on as many as 28 different vehicle brands. Static calibration is possible on Audi, Honda, Hyundai, Kia, Mazda, Mercedes, Renault, Seat, Skoda and Volkswagen; for Nissan, Subaru, Toyota and Lexus panels are also available. It also possible, in full respect of the directions from the manufacturers, to dynamically calibrate BMW, Ford, Mitsubishi and Volvo systems. With the new version of the system the offer has become modular: you can buy the basic package and later add kits dedicated to each manufacturer, saving money and workshop space. Sensors can be adjusted, according to the geometric axis (ie the rear axle) of the vehicle, through two screws.

The measuring range depends on the system, and that is why there are kits with different optical targets and different calibration procedures. The base module is an angular plate to be fastened to the support; a laser (supplied with the base kit) with a graduated scale can be added later, as required by systems found on Volkswagen and Mercedes. Radar Kit 1 is an expansion kit specifically designed for the radar-based ADAS systems, both with  and without a mirror, used by BMW, Volkswagen. Radar kit 2, on the other hand, was specifically designed for the mirror-less radar system used  on Mercedes-Benz models


Ever-growing coverage

Regardless of the nature of the system (camera or radar), Mega Macs helps the repairer to calibrate the system with a step-by-step procedure and then makes a record of the calibration document with date and time in the system’s memory. The CSC tool has a 95% coverage of the Adas equipped vehicles currently circulating on European roads, and is already used by over one thousand EU workshops. Three camera calibration kits, used for example by park assist systems, are the latest range extension. Working on these systems may be necessary, as indicated by the Daimler and Volkswagen groups, following an intervention on a vehicle front and rear wheel set up, when replacing a rear-view mirror, in the event of a small accident or an upgrade of the vehicle System’s control device. The correct alignment of the panels is guaranteed by the Mega Macs Diagnostic Tool Kit.



News for the workshop – Routine maintenance for tomorrow’s systems

The SEG Series Spotlight adjustment devices, allow perfect adjustment of the most complex headlamps, such as HellaMultibeam Led lights, used by Mercedes-Benz as standard equipment on the new E-Class (and awarded with the Daimler Supplier Award). Equally advanced are the BPC battery chargers, designed for AGM (Active Gel Mat) batteries used by vehicles with stop & start systems and therefore subjected to particularly stressful work-loads. BehrHella Service, the joint venture devoted to engine cooling and air conditioning systems, offers its new range of spare parts Premium Line, which is made up of more than 4500 high-end vehicle codes from OEM manufacturers such as Behr, AKG or Visteon; in addition, the standard line, with 3000 codes, is capable of covering a very large share of the vehicles currently on our roads as well as a number of commercial and industrial vehicles.
