11.4 The Role of Cybersecurity in ADAS Diagnostics
Cybersecurity is expected to play an increasingly important role in ADAS diagnostics in the future. As ADAS systems become more connected and integrated with other vehicle systems, they become more vulnerable to cyberattacks.
It is important to ensure that the diagnostic systems are secure and that they cannot be used to compromise the ADAS systems. Mercedes-Benz is expected to implement robust cybersecurity measures to protect the ADAS systems from cyberattacks.
12. Ensuring Safety During ADAS Diagnostics and Repairs
What safety precautions should be taken during ADAS diagnostics and repairs on Mercedes-Benz vehicles?
Safety precautions during ADAS diagnostics and repairs on Mercedes-Benz vehicles include disconnecting the battery, using appropriate personal protective equipment (PPE), and following manufacturer-specified procedures to avoid accidental system activation or sensor damage; MERCEDES-DIAGNOSTIC-TOOL.EDU.VN emphasizes these safety measures in all our training
