This initiated bill requires manufacturers of certain motor vehicles to standardize the vehicle on-board diagnostic systems and make those systems accessible to owners and independent repair facilities. It requires the Attorney General to designate an independent entity to administer the accessibility of vehicle on-board diagnostic systems by adopting standards and developing policies. The initiated bill requires the release of certain diagnostic repair tools, parts, software and components depending on model year of the motor vehicle. It also requires certain motor vehicles to be equipped with a standard access platform and provides exclusions for information otherwise required to be shared with owners or independent repair shops if that information is necessary for immobilizer systems or security-related modules. The initiated bill provides for enforcement by civil action of the provisions related to access and information sharing and provides the available damages. It also requires that the Attorney General establish a notice relating to motor vehicle telematics systems and requires dealers of certain motor vehicles to provide that notice to potential owners of motor vehicles, and it provides for an administrative consequence if a dealer does not comply.
