Section 2 - Access by Owners of Motor Vehicles and by Independent Repair Facilities to Motor Vehicle Manufacturer Diagnostic and Repair Information and Diagnostic Repair Tools Otherwise Made Available to Dealers

Section 2. (a) Except as provided in subsection (e), for model year 2002 motor vehicles and thereafter and model year 2013 heavy duty vehicles and thereafter, a manufacturer of motor vehicles sold in the commonwealth shall make available for purchase by owners of motor vehicles manufactured by such manufacturer and by independent repair facilities the same diagnostic and repair information, including repair technical updates, that such manufacturer makes available to its dealers through the manufacturer's internet-based diagnostic and repair information system or other electronically accessible manufacturer's repair information system. All content in any such manufacturer's repair information system shall be made available to owners and to independent repair facilities in the same form and manner and to the same extent as is made available to dealers utilizing such diagnostic and repair information system. Each manufacturer shall provide access to such manufacturer's diagnostic and repair information system for purchase by owners and independent repair facilities on a daily, monthly and yearly subscription basis and upon fair and reasonable terms.
(b) A manufacturer that sells any diagnostic, service or repair information to an independent repair facility or other third party provider in a format that is standardized with other manufacturers, and on terms and conditions more favorable than the manner and the terms and conditions which a dealer obtains the same diagnostic, service or repair information, shall be prohibited from requiring any dealer to continue purchasing diagnostic, service or repair information in a proprietary format, unless such proprietary format includes diagnostic, service, repair or dealership operations information or functionality that is not available in such standardized format.
(c) (1) For model year 2002 motor vehicles and thereafter and model year 2013 heavy duty vehicles and thereafter, each manufacturer of motor vehicles sold in the commonwealth shall make available for purchase by owners and independent repair facilities all diagnostic repair tools incorporating the same diagnostic, repair and wireless capabilities that such manufacturer makes available to its dealers. Such tools shall incorporate the same functional repair capabilities that such manufacturer makes available to dealers. Each manufacturer shall offer such tools for sale to owners and to independent repair facilities upon fair and reasonable terms.
(2) Any diagnostic tool or information necessary to diagnose, service or repair a motor vehicle that a manufacturer sells to an independent repair facility in a manner and on terms and conditions more favorable than the manner and the terms and conditions which a dealer obtains the same diagnostic tool or information necessary to diagnose, service or repair a motor vehicle, shall also be offered to the dealer in the same manner and on the same terms and conditions as provided to such independent repair facility.
A manufacturer that sells to an independent repair facility any diagnostic tool necessary to diagnose, service or repair a motor vehicle and such diagnostic tool communicates with the vehicle using the same non-proprietary interface used by other manufacturers, the manufacturer delivering such a diagnostic tool shall be prohibited from requiring any dealer from continuing to purchase that manufacturer's proprietary tool and interface unless such proprietary interface has a capability not available in the non-proprietary interface.
(3) Each manufacturer shall provide diagnostic repair information to each aftermarket scan tool company and each third party service information provider with whom the manufacturer has appropriate licensing, contractual or confidentiality agreements for the sole purpose of building aftermarket diagnostic tools and third party service information publications and systems. Once a manufacturer makes such information available pursuant to this section, the manufacturer shall be considered to have satisfied its obligations under this section and thereafter not be responsible for the content and functionality of aftermarket diagnostic tools or service information systems.
(d) (1) Beginning in model year 2018, except as provided in subsection (e), manufacturers of motor vehicles sold in the commonwealth, including heavy duty vehicles that are not heavy duty vehicles built to custom specifications sold in the commonwealth for commercial purposes, shall provide access to their onboard diagnostic and repair information system, as required under this section, using an off-the-shelf personal computer with sufficient memory, processor speed, connectivity and other capabilities as specified by the vehicle manufacturer and: (i) a non-proprietary vehicle interface device that complies with the Society of Automotive Engineers standard J2534, Society of Automotive Engineers J1939, commonly referred to as SAE J2534 and SAE J1939, the International Organization for Standardization standard 22900, commonly referred to as ISO 22900 or any successor to SAE J2534, SAE J1939 or ISO 22900 as may be accepted or published by the Society of Automotive Engineers or the International Organization for Standardization; (ii) an onboard diagnostic and repair information system integrated and entirely self-contained within the vehicle, including, but not limited to, service information systems integrated into an onboard display; or (iii) a system that provides direct access to onboard diagnostic and repair information through a non-proprietary vehicle interface, such as ethernet, universal serial bus or digital versatile disc. Each manufacturer shall provide access to the same onboard diagnostic and repair information available to their dealers, including technical updates to such onboard systems, through such non-proprietary interfaces as referenced in this paragraph. Nothing in this chapter shall be construed to require a dealer to use a non-proprietary vehicle interface specified in this paragraph, nor shall this chapter be construed to prohibit a manufacturer from developing a proprietary vehicle diagnostic and reprogramming device; provided, however, that: (i) the manufacturer also complies with this paragraph; and (ii) the manufacturer also makes this device available to independent repair facilities upon fair and reasonable terms and otherwise complies with subsection (a).
Notwithstanding anything in the preceding paragraph, motor vehicle owners' and independent repair facilities' access to vehicle on-board diagnostic systems shall be standardized and not require any authorization by the manufacturer, directly or indirectly, unless the authorization system for access to vehicle networks and their on-board diagnostic systems is standardized across all makes and models sold in the Commonwealth and is administered by an entity unaffiliated with a manufacturer.
(2) No manufacturer shall be prohibited from making proprietary tools available to dealers if such tools are for a specific specialized diagnostic or repair procedure developed for the sole purpose of a customer service campaign meeting the requirements set out in 49 CFR 579.5, or performance of a specific technical service bulletin or recall after the vehicle was produced, and where original vehicle design was not originally intended for direct interface through a non-proprietary interface set out in paragraph (1). Provision of such proprietary tools under this paragraph shall not constitute a violation of this chapter even if such tools provide functions not available through the interface set forth in paragraph (1); provided, however, that such proprietary tools are also available to the aftermarket upon fair and reasonable terms. Nothing in this paragraph authorizes manufacturers to exclusively develop proprietary tools, without a non-proprietary equivalent as set forth in paragraph (1), for diagnostic or repair procedures that fall outside the provisions of this paragraph or to otherwise operate in a manner inconsistent with paragraph (1).
(e) Manufacturers of motor vehicles sold in the commonwealth may exclude diagnostic, service and repair information necessary to reset an immobilizer system or security-related electronic modules from information provided to owners and independent repair facilities. If excluded under this subsection, the information necessary to reset an immobilizer system or security-related electronic modules shall be obtained by owners and independent repair facilities through the secure data release model system currently used by the National Automotive Service Task Force or other known, reliable and accepted systems.
(f) Commencing in model year 2022 and thereafter a manufacturer of motor vehicles sold in the Commonwealth, including heavy duty vehicles having a gross vehicle weight rating of more than 14,000 pounds, that utilizes a telematics system shall be required to equip such vehicles with an inter-operable, standardized and open access platform across all of the manufacturer's makes and models. Such platform shall be capable of securely communicating all mechanical data emanating directly from the motor vehicle via direct data connection to the platform. Such platform shall be directly accessible by the owner of the vehicle through a mobile-based application and, upon the authorization of the vehicle owner, all mechanical data shall be directly accessible by an independent repair facility or a class 1 dealer licensed pursuant to section 58 of chapter 140 limited to the time to complete the repair or for a period of time agreed to by the vehicle owner for the purposes of maintaining, diagnosing and repairing the motor vehicle. Access shall include the ability to send commands to in-vehicle components if needed for purposes of maintenance, diagnostics and repair.
(g) The Attorney General is hereby directed to establish for prospective vehicle owners a motor vehicle telematics system notice that includes, but is not limited to, the following features: (i) an explanation of motor vehicle telematics and its purposes, (ii) a description summarizing the mechanical data collected, stored and transmitted by a telematics system, (iii) the prospective owner's ability to access the vehicle's mechanical data through a mobile device, and (iv) an owner's right to authorize an independent repair facility to access the vehicle's mechanical data for vehicle diagnostics, repair and maintenance purposes. The notice form shall provide for the prospective owner's signature certifying that the prospective owner has read the telematics system notice.
(h) When selling or leasing motor vehicles containing a telematics system, a dealer holding a class 1 or class 2 license as defined in section 58 of chapter 140 shall provide the motor vehicle telematics system notice to the prospective owner, obtain the prospective owner's signed certification that he or she has read the notice, and provide a copy of the signed notice to the prospective owner. A dealer's failure to comply with the provisions of this subsection shall be grounds for any action by the licensing authority relative to the dealer's license, up to and including revocation, pursuant to section 59 of chapter 140.
