A system for providing privileged access to an internal vehicle communication network is provided. The system includes a presentation network bus configured to provide listen-only access to a subset of in-vehicle networks, a security system configured to enable access to the presentation network bus by verifying access credentials, and a diagnostic service system configured to control access to the presentation network bus. The diagnostic service system is configured to receive a diagnostic service request after the access credentials have been verified to enable the presentation network busses for listen-only access to the subset of the in-vehicle networks. The presentation network busses may be enabled for the listen-only access after credential verification by the security system and in response to receipt of a diagnostic service request from the diagnostic service system requesting that the presentation network busses be enabled.
