COMPLIANCE WITH NEW YORK STATE GENERAL BUSINESS LAW §399‑CCCCC (CONNECTED VEHICLE SERVICE; DOMESTIC VIOLENCE VICTIMS) DESCRIPTION This Service Information is issued in accordance with New York State General Business Law §399CCCCC (Connected Vehicle Service; Domestic Violence Victims). This regulation is intended to protect victims of domestic violence by allowing them to request the termination of third-party access (including access by an alleged abuser) to connected vehicle services, such as vehicle location tracking and remote control functions. To support this requirement, this Service Information enables confirmation of whether a vehicle is subject to connected vehicle services by referring to the SUBJECT VIN & PRODUCTION DATE RANGE, and provides guidance on the procedure to terminate such services when a customer requests the removal of third-party access for an applicable vehicle. Effective July 1, 2026, if a customer requests action under this regulation, a CMU/CDC software update must be performed to enable appropriate control of connected vehicle service access. If no request is made by the customer, the CMU/CDC software update is not required. REPAIR PROCEDURE 1. Confirm that the customer has requested deactivation of connected services in accordance with New York State General Business Law related action. 2. Perform the CMU/CDC software update according to the procedures outlined in the appropriate TSB shown in the table below: |
