Looking for information on a model from a previous year? Since we are always improving and innovating from year to year, models may disappear from our website or get replaced with a new version. Here is a list of recently replaced models and a button to download a pdf with more information.
The BAR On-Board Diagnostic Inspection System (BAR-OIS) is required to inspect most model year 2000 and newer gasoline vehicles, hybrid vehicles, and alternative-fuel vehicles and most model year 1998 and newer diesel vehicles. Implemented statewide on March 9, 2015, the system consists of a certified Data Acquisition Device (DAD) and off-the-shelf equipment. The BAR-OIS uses the California BAR-OIS software to communicate with BAR's central database through an internet connection.
Manuals are in PDF format which requires a free program Adobe Reader in order to view them after downloading (this program is probably already installed on your computer). Instructions for installing and help topics can be found on the Adobe Reader Help page.
DEC held a webinar on Tuesday, September 13, 2022, from 1:00 - 2:30 p.m. to provide an overview of the Advanced Clean Trucks DRAFT reporting template and accompanying guidance and to accept feedback from applicable entities.DEC held a webinar on Friday, September 16, 2022, regarding its evaluation of potential adoption of the California Advanced Clean Cars II (ACC II) regulation. DEC staff provided relevant policy background and an overview the ACC II regulation. The slide presentation is available as a downloadable PDF. Comments related to the potential rulemaking may be submitted to ACCII.Air@dec.ny.gov.DEC held a webinar on Wednesday, September 28, 2022, regarding its evaluation of potential adoption of the California Heavy-Duty Low NOx Omnibus and California Phase 2 Greenhouse Gas Standards regulations. DEC staff provided relevant policy background and an overview the California Heavy-Duty Low NOx Omnibus and California Phase 2 Greenhouse Gas Standards regulations. The slide presentation is available as a downloadable PDF. Comments related to the potential rulemaking may be submitted to email@example.com.DEC held a webinar on Thursday, September 29, 2022, regarding potential proposed revisions to Subpart 217-5, Heavy Duty Inspection and Maintenance Program, to reflect revised Heavy-Duty Diesel Vehicle Inspection and Maintenance Program ("HDDV I/M") requirements. DEC staff provided relevant policy background and an overview of the potential proposed revisions to Subpart 217-5 and an overview of the revised HDDV I/M requirements. The slide presentation is available as a downloadable PDF. Comments related to the potential rulemaking may be submitted to firstname.lastname@example.org.
Diesel engines are durable and efficient. However, because they consume diesel fuel, a complicated mix of petroleum components, they produce some pollutants. A small amount of the fuel exits the engine unburned. These airborne hydrocarbons can form larger particles in the atmosphere when they contact airborne dust and other particles.
Unlike gasoline engines, which may not get enough air into the cylinder for combustion, diesel engines operate with excess air so emissions of carbon monoxide are very low, though still measurable. Carbon monoxide is a colorless, odorless gas that combines with blood and limits its ability to transport oxygen. Since the engines are consuming fuel and air and create heat in the combustion process, nitrogen from the air can be transformed into nitrogen oxides which are reddish brown gases that irritate the lungs and eyes.
A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from motor vehicle engines into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are used with gasoline and diesel-powered engines.
The vehicle emission control information (VECI) label, located in the vehicle's engine compartment, includes emissions certification, engine family or test group, engine displacement, on-board diagnostics, model year, fuel type, and catalyst information. Sample VECI labels are available for download (PDF). If the VECI cannot be located, an OEM dealer may be contacted to obtain a replacement VECI label containing the correct test group or engine family information.
Emissions tests for heavy diesel commercial motor vehicles must be performed by a certified technician at a vehicle inspection centre that has entered into an agreement with the Ontario government. These private operators:
Your vehicle needs an emissions test if it is a heavy diesel commercial motor vehicle with a registered gross weight over 4,500 kilograms, such as a large truck or bus, and the vehicle is either:
Heavy diesel commercial motor vehicles are required to be emissions tested annually. If you own a heavy diesel commercial motor vehicle that requires an emissions test, you will receive a registration renewal notice in the mail indicating that an emissions test is required to renew your vehicle registration.
A small number of heavy diesel commercial motor vehicles are expected to be identified with unique testing characteristics that prevent them from communicating with an on-board diagnostic test (OBD) unit. These vehicles cannot be OBD-tested to determine if the OBD system has an active emission-related Diagnostic Trouble Code (DTC).
A small number of heavy diesel commercial motor vehicles are expected to be identified with unique testing characteristics that require exceptions to diagnostic monitor checks that are part of the on-board diagnostic test. 2b1af7f3a8
