(a) “Capture rate” means the percentage of in-use vehicles or engines subject to recall that must be corrected to bring the class or category of vehicles or engines into compliance. The number of vehicles subject to recall shall be based on the actual number of vehicles in use as verified by the Department of Motor Vehicles registration records, or vehicle or engine registration records compiled and prepared by R. L. Polk and Company or a comparable source at the time a recall is initiated.

(b) “Corrective Action” refers to any action taken by the manufacturer to remedy a noncompliance or nonconformity of the specified performance standards. Corrective action may include recall, extended warranty, or other action ordered or deemed necessary by the Executive Officer. The Executive Officer shall require direct notification of corrective action to vehicle or engine owners.

(c) “Days,” when computing any period of time, means business days, unless otherwise noted.

(d) “Emission control component” or “emission-related component” means a device, system, or assembly that:

(e) “Exhaust Gas Recirculation Cooler” means a device that reduces the temperature of gases that have been exhausted from the combustion chamber and are routed back into the engine.

(f) “Exhaust Gas Recirculation Valve” means a device that reduces emissions by routing exhaust gases from the combustion chamber back into the engine to be mixed with incoming air before or during combustion.

(g) “Emission-Related Failure” means an in-use failure of a device, component, system, or assembly that can affect an emission control component or emission-related component or system from functioning properly or as approved.

(h) “Emission Warranty Claim” means an adjustment, inspection, repair, or replacement of a specific emission-related component within the statutory warranty period for which the vehicle or engine manufacturer is invoiced or solicited by a repairing agent for compensation pursuant to title 13, California Code of Regulations, division 3, chapter 1, article 6 and subject to this article.

(i) “Executive Officer” means the Executive Officer of the Air Resources Board or his or her authorized representative.

(j) “Exhaust after-treatment device” means any device or system designed to reduce emissions from post-combustion exhaust emissions, including those components that transport the exhaust emissions from the engine to the after-treatment device, described in the manufacturer's application for certification, and installed on a vehicle or engine certified for sale in California.

(k) “Extended Warranty” means corrective action required by the Executive Officer that extends the warranty time and mileage periods for a specific emissions-related component pursuant to this article. The extended warranty shall be at a minimum equal to or more than the applicable certified useful life period of that vehicle or engine. Direct notification of corrective action to vehicle or engine owners shall be required.

(l) “Fuel Injector” means any device designed to deliver fuel to a cylinder or intake air system.

(m) “Hydrocarbon Injector” means any device designed to increase exhaust temperatures by injecting fuel into the exhaust stream.

(n) “Nonconformity” or “noncompliance” exists whenever a class or category of vehicles or engines, although properly maintained and used, experience a failure of the performance standards specified in section 2143 within their useful lives.

(o) “On-board computer” means any device that monitors or controls the performance of components that may impact emissions.

(p) “Quarterly reports” refer to the following calendar periods: January 1- March 31, April 1-June 30, July 1-September 30, October 1-December 31.

(q) “Recall” means an inspection, repair, adjustment, or modification program initiated and conducted by a manufacturer or its agent or representative to remedy any nonconformity, pursuant to this article, for which direct notification of vehicle or engine owners shall be required.

(r) “Systemic Failure” means any emission-control component as defined in this article, found to have valid failures that that exceed the thresholds specified in section 2143.

(s) “Turbocharger” means a forced induction device that is turbine-driven and used for the purpose of forcing compressed air into the combustion chamber.

(t) “Urea Doser” means any device designed to deliver a reductant, such as urea, into the exhaust stream in order to reduce emissions.

(u) “Valid failure” or “valid failure rate” means an emission-control component or emission-related component that was properly diagnosed and replaced under warranty by an authorized warranty station and represents the true and accurate failures of a specific component after proper analysis and screening of the applicable warranty data authorized and acceptable to the Executive Officer, pursuant to this article.

(v) “Vehicle or engine manufacturer” means the manufacturer granted certification for a new California-certified motor vehicle or motor vehicle engine.

(w) “Zero-emission powertrain” means an all-electric or hydrogen fuel-cell powertrain assembly, which includes (if applicable) the electric traction motor, system controller, generator, on-board charger, battery management system, thermal management systems, energy storage system (batteries, capacitors, and flywheels), inverter, fuel-cell stack, and the interface at which electrical power is converted to tractive mechanical power or vice-versa (in the case of a regenerative braking system), certified pursuant to the requirements in section 1956(a)(8), title 13, California Code of Regulations.
