Replace shared vehicle diagnostic credentials with accountable identities
Which technician, tool, and service action is authorized for a specific vehicle and time window?
Operational pain
Reusable workshop credentials and cloned diagnostic tools weaken attribution and can unlock functions across an entire fleet.
Trigger
Dealer-platform upgrade, right-to-repair design, or abuse of diagnostic access.
QNSI contribution
Connect the decision to a controlled security path
Register tool and service identities, certificate issuers, privileges, target cohorts, and rotation status in QNSI.
Decision artifact
A diagnostic trust ledger linking technician authorization, tool identity, vehicle scope, action, and expiry.
What still requires validation
The manufacturer tests offline workshops, emergency repair, privacy, authorization enforcement, revocation, and regulatory access.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
