Title of Recall SRL250925 – Change parameters in front radar sensor (RDF) control unit – RDF-HOE

As part of our continuous quality monitoring we have identified that the vehicle-specific RDF3 (radar front end) installation height value has not been parameterized in Econic 956 Actros 963 Arocs 964 Atego 967 and eActros 983 model vehicles. Instead of the vehicle-specific installation height value a substitute value of 1 m has been entered. The substitute value is always higher than the actual installation situation. RDF3 is responsible for object recognition detecting clearance as well as close and long-range processing. It can also detect the ability to drive under and over objects which enables a radar-only reaction as part of the ABA functionality. Since the sensor value is parameterized higher than the actual installation height trucks ahead may not be detected particularly on inclines. This may lead to the fact that automatic braking by the ABA may not being triggered. Furthermore incorrect parameterization may lead to objects on the ground such as tracks manhole covers etc. being erroneously detected as obstacles causing ABA to brake the vehicle. This may increase the risk of accident.

As a permanent measure we wish to determine the installation height of the RDF3 manually and parameterize the determined value in potentially affected vehicles as part of this recall campaign.
