Aftermarket Parts Procedures Working Group - Follow Up Meeting on Tuners, Programmers, and In-Line Modules

The California Air Resources Board (CARB) invites you to participate in a follow up work group meeting for manufacturers of Tuners, Programmers, and In-Line Modules or those who use these devices as part of their performance product(s). The discussion will focus on the need for manufacturers to gather calibration identification codes, calibration verification numbers, and identification numbers from a purchaser’s vehicle.  For those who cannot attend in person, a webinar will be available.

When available, all meeting materials will be posted on the Aftermarket Parts Public Meeting webpage.

Please see below for additional details regarding the work group meeting:

California Anti Tampering Laws (Vehicle Code (VC) 27156 and VC 38391) prohibit the sale, operation, and modification of engines or vehicles from their originally certified configuration.  The aftermarket parts program evaluation procedures, “Procedures for Exemption of Add-on and Modified Parts” (Procedures), provide the process and criteria for manufacturers of add-on and modified parts to obtain exemptions to legally sell parts in California.  Add-on and modified parts are defined in California Code of Regulations, title13, section 1900 (b) (1 and 10) and section 2222.  The Procedures are intended to be robust enough to demonstrate that the aftermarket parts will not adversely impact emissions, the original emissions control system, and the On-Board Diagnostics system of the certified engine or vehicle, while providing industry with a less complicated evaluation protocol.

The Procedures were last updated in June 1990.  Since that time, engines, vehicles, emission control technologies and strategies have changed and become more complex.  The Procedures have provided industry and CARB with the tools needed to continue the evaluation of aftermarket parts as the standards and test procedures have changed.  However, staff wishes to revisit the processes and test protocols to ensure they reflect current procedures and technologies while providing the tools necessary to evaluate engines and vehicles of the future.  The purpose of the workshop is to discuss a draft replacement to the Procedures and solicit additional feedback..
