43105.5. (a)  For all 1994 and later model-year motor vehicles equipped with on board diagnostic systems (OBD’s) and certified in accordance with the test procedures adopted pursuant to Section 43104, the state board, not later than January 1, 2002, shall adopt regulations that require a motor vehicle manufacturer to do all of the following to the extent not limited or prohibited by federal law (the regulations adopted by the state board pursuant to this provision may include subject matter similar to the subject matter included in regulations adopted by the United States Environmental Protection Agency):
(1)  Make available, within a reasonable period of time, and by reasonable business means, including, but not limited to, use of the Internet, as determined by the state board, to all covered persons, the full contents of all manuals, technical service bulletins, and training materials regarding emissions-related motor vehicle information that is made available to their franchised dealerships.
(2)  Make available for sale to all covered persons the manufacturer’s emissions-related enhanced diagnostic tools, and make emissions-related enhanced data stream information and bidirectional controls related to tools available in electronic format to equipment and tool companies.
(3)  If the motor vehicle manufacturer uses reprogrammable computer chips in its motor vehicles, provide equipment and tool companies with the information that is provided by the manufacturer to its dealerships to allow those companies to incorporate into aftermarket tools the same reprogramming capability.
(4)  Make available to all covered persons, within a reasonable period of time, a general description of their on board diagnostic systems (OBD II) for the 1996 and subsequent model-years, which shall contain the information described in this paragraph. For each monitoring system utilized by a manufacturer that illuminates the OBD II malfunction indicator light, the motor vehicle manufacturer shall provide all of the following:
(A)  A general description of the operation of the monitor, including a description of the parameter that is being monitored.
(B)  A listing of all typical OBD II diagnostic trouble codes associated with each monitor.
(C)  A description of the typical enabling conditions for each monitor to execute during vehicle operation, including, but not limited to, minimum and maximum intake air and engine coolant temperature, vehicle speed range, and time after engine startup.
(D)  A listing of each monitor sequence, execution frequency, and typical duration.
(E)  A listing of typical malfunction thresholds for each monitor.
(F)  For OBD II parameters for specific vehicles that deviate from the typical parameters, the OBD II description shall indicate the deviation and provide a separate listing of the typical value for those vehicles.
(G)  The information required by this paragraph shall not include specific algorithms, specific software code, or specific calibration data beyond that required to be made available through the generic scan tool in federal and California on board diagnostic regulations.
(5)  Not utilize any access or recognition code or any type of encryption for the purpose of preventing a vehicle owner from using an emissions-related motor vehicle part with the exception of the powertrain control modules, engine control modules, and transmission control modules, that has not been manufactured by that manufacturer or any of its original equipment suppliers.
(6)  Provide to all covered persons information regarding initialization procedures relating to immobilizer circuits or other lockout devices to reinitialize vehicle on board computers that employ integral vehicle security systems if necessary to repair or replace an emissions-related part, or if necessary for the proper installation of vehicle on board computers that employ integral vehicle security systems.
(7)  All information required to be provided to covered persons by this section shall be provided, for fair, reasonable, and nondiscriminatory compensation, in a format that is readily accessible to all covered persons, as determined by the state board.
(b)  Any information required to be disclosed pursuant to a final regulation adopted under this section that the motor vehicle manufacturer demonstrates to a court, on a case-by-case basis, to be a trade secret pursuant to the Uniform Trade Secret Act contained in Title 5 (commencing with Section 3426) of Part 1 of Division 4 of the Civil Code, shall be exempt from disclosure, unless the court, upon the request of a covered person seeking disclosure of the information, determines that the disclosure of the information is necessary to mitigate anticompetitive effects. In making this determination, the court shall consider, among other things, the practices of any motor vehicle manufacturer that results in the fullest disclosure of information listed in paragraph (4) of subdivision (a). In actions subject to this subdivision, the court shall preserve the secrecy of an alleged trade secret by reasonable means, which may include granting a protective order in connection with discovery proceedings, holding an in-camera hearing, sealing the record of the action, or ordering any person involved in the litigation not to disclose an alleged trade secret without prior court approval.
(c)  If information is required to be disclosed by a motor vehicle manufacturer pursuant to subdivision (b), the court shall allow for the imposition of reasonable business conditions as a condition of disclosure, and may include punitive sanctions for the improper release of information that is determined to be a trade secret to a competitor of the manufacturer. The court shall also provide for fair, reasonable, and nondiscrimatory compensation to the motor vehicle manufacturer for the disclosure of information determined by the court to be a trade secret and required to be disclosed pursuant to subdivision (b). The court shall provide for the dissemination of trade secret information required to be disclosed pursuant to subdivision (b) through licensing agreements and the collection of reasonable licensing fees. If the court determines that disclosure of any of the information required to be disclosed under subdivision (b) constitutes a taking of personal property, a jury trial shall be held to determine the amount of compensation for that taking, unless waived by the motor vehicle manufacturer.
(d)  The state board shall periodically conduct surveys to determine whether the information requirements imposed by this section are being fulfilled by actual field availability of the information.
(e)  If the executive officer of the state board obtains credible evidence that a motor vehicle manufacturer has failed to comply with any of the requirements of this section or the regulations adopted by the state board, the executive officer shall issue a notice to comply to the manufacturer. Not later than 30 days after issuance of the notice to comply, the vehicle manufacturer shall submit to the executive officer a compliance plan, unless within that 30-day period the manufacturer requests an administrative hearing to contest the basis or scope of the notice to comply in accordance with subdivision (f). The executive officer shall accept the compliance plan if it provides adequate demonstration that the manufacturer will come into compliance with this section and the board’s implementing regulations within 45 days following submission of the plan. However, the executive officer may extend the compliance period if the executive officer determines that the violation cannot be remedied within that period.
(f)  If the motor vehicle manufacturer contests a notice to comply pursuant to subdivision (e) or the executive officer rejects the compliance plan submitted by the manufacturer, an administrative hearing shall be conducted by a hearing officer appointed by the state board, in accordance with procedures established by the state board. The hearing procedures shall provide the manufacturer and any other interested party at least 30 days notice of the hearing. If, after the hearing, the hearing officer appointed by the state board finds that the motor vehicle manufacturer has failed to comply with any of the requirements of this section or the regulations adopted by the state board, and the manufacturer fails to correct the violation with 30 days from the date of the finding, the hearing officer may impose a civil penalty upon the manufacturer in an amount not to exceed twenty-five thousand dollars ($25,000) per day per violation until the violation is corrected, as determined in accordance with the hearing procedures established by the state board. The hearing procedures may provide additional time for compliance prior to imposing a civil penalty. If so, the hearing officer may grant additional time for compliance if he or she determines that the violation cannot be remedied within 30 days of the finding that a violation has occurred.
(g)  Nothing in this section is intended to authorize the infringement of intellectual property rights embodied in United States patents, trademarks, or copyrights, to the extent those rights may be exercised consistently with any other federal laws.
