From Diagnostic Complexity to Secure Global Deployment
Modern vehicle diagnostics are becoming harder to manage as software orientated functions, cybersecurity requirements, and regulatory obligations continue to grow. For OHW customers, the challenge is no longer only enabling diagnostic access – it is doing so in a way that supports maintenance workflows while enforcing secure, controlled access for diagnostic users at scale.
Key challenges
Rising diagnostics complexity
Software-driven vehicle systems make diagnostics more complex in terms of management, validation, and scaling across service ecosystems.
Access must stay secure
Regulations require vehicle functions and diagnostic interfaces to be accessible, but only under controlled conditions.
Security vs. usability conflict
Access must be open enough for maintenance, yet restricted enough to prevent misuse and unauthorized operations.
High effort with existing tools
Many current solutions are difficult to deploy globally and lack built-in governance for secure access management.
Key benefits
Secure diagnostics by design
Built-in authentication and authorization help protect vehicle functions without adding external security layers.
Compliance readiness out of the box
Supports regulatory requirements for secure access and controlled diagnostics, including CRA-related needs.
Scalable from pilot to global rollout
Enables a consistent diagnostic access model across regions, users, and service networks.
Lower lifecycle effort and cost
Reduces the operational burden of implementing and maintaining secure diagnostics infrastructure.
