CSC Tool & automotive diagnostic unit
Here you will find useful knowledge and important tips regarding the topic of Adaptive Cruise Control (ACC) and/or automatic ACC distance control as well as the calibration of ACC radar sensors.
Important safety note
The expanded modular CSC Tool system (CSC = Camera and Sensor Calibration) from Hella Gutmann Solutions allows workshops to professionally calibrate cameras on vehicles from numerous car brands in conjunction with current mega macs diagnostic units. Furthermore, due to additional expansions, all current common radar systems can also be aligned.
The CSC Tool is also beneficial for workshops due to the increasing importance of driver assistance systems – as these have been particularly popular among drivers for years. And the trend is increasing. Whether intelligent cruise control via radar, lane assistant or automatic parking assist – to name just a few – the driver assistance systems not only provide greater comfort, but also a higher level of safety. Provided they are aligned regularly.
The perfect aid for this is the CSC Tool in conjunction with a mega macs diagnostic unit. Here, the diagnostic unit takes over the communication with the control unit and initiates the calibration. To execute the calibration itself, however, a suitable calibration panel is required and it must be aligned correctly. It is here that the CSC Tool comes into play.
The requirements for this are the CSC Tool (familiar from camera calibrations) with optional radar attachment, a mega macs diagnostic unit, as well as a battery charger.
Our simplified practical example, based on an Audi RS 7, shows the main steps which should be noted during radar adjustment for the Adaptive Cruise Control System (ACC).
The vehicle is placed on a set-up testing station. In addition to the CSC Tool with radar attachment, the mechanic needs a connected battery charger as well as the mega macs diagnostic unit. From the beginning, the mega macs will guide you through the process.
For the radar adjustment, the CSC Tool must be aligned parallel to the front of the vehicle, and to the vehicle's longitudinal axis (in the example, to the rear left wheel bracket).
The vehicle distance to be maintained is – according to the vehicle – specified by the mega macs and must be measured at the designated points (vehicle dependent). The bubble level helps to check the alignment of the CSC Tool.
The Audi RS 7 has two radar sensors which must be aligned one after the other. The mega macs specifies the sequence. Before adjusting, the sensor must be exposed.
The vehicle is now ready for the adjustment of the first sensor.
The radar reflector (= angle adjustment plate) has a three-level mounting bracket. It will be aligned in this manner with a positive angle upward (level 1), precisely perpendicular (level 2) or with a tilt downward (level 3). This means that normal driving as well as acceleration and braking processes are taken into account (compare with graphic on the right-hand side).
All three levels have to be set one after the other.
The mega macs will guide you through each process.
If the sensor requires re-adjustment, the mega macs provides precise instructions.
Following successful adjustment of the first sensor, this is shown.
For the second sensor, the described steps are carried out in the same way.
Once the second sensor has also been successfully adjusted, the radar functions of the RS 7 can be used optimally again. With confidence!
