Location of liquid fuel leak, reason for smoke test failure, E.O. numbers for aftermarket parts, component which fails in "other" category, monitors not run to completion, location of inaccessible canister for LPFET. What must be noted on a VIR? Check for a BAR Referee Label, and continue with the test if equipped. A vehicle has been converted from diesel to gasoline. All equipment is installed for the conversion. What action should the inspector take? Verify the aftermarket parts are approved. What action should taken be when testing a vehicle with aftermarket parts? Basic What program area performs only TSI tests on a biennial basis? Enhanced What program area performs both TSI & ASM tests on a biennial basis? Change of ownership What program area performs only TSI tests on change of ownership? After the tail pipe sampling part of the test. When is the tailpipe (idle) smoke test performed during a BAR97 inspection? When the OIS prompts you. When is the tailpipe (idle) smoke test performed during a OIS inspection? Obtain the part's identification numbers/name, and refer to the parts, manufacturer's catalogs/website to see it is designated as either a replacement part, and/or allowed for street use on emission-controlled vehicles. What action should be taken when testing a vehicle with an aftermarket carburetor? During WOT or a backfire. When does the PCV valve stop the flow of crankcase vapors into the intake? the vehicle to stumble or die Opening the EGR during idle should cause _________.

Zero Air, BAR 97 High, BAR 97 Low What are the names of the calibration gases used by the BAR 97 EIS? Nitrogen What gas is used to perform the LPFET? Attempt to verify program area and directed status of the vehicle. If this can be confirmed, the technician can proceed, but if the info is incorrect, the certificate may not be valid. If the certificate is valid, it may not be communicated to DMV. During the smog inspection, the BAR97 EIS must contact the Vehicle Information Database (VID) twice; once to retrieve vehicle info an once to submit info. If the BAR97 EIS fails to communicate, due to a communication error, how should the technician proceed? Enter the odometer reading in kilometers. No conversion is necessary.

Only the evaporative system monitor Which monitors are allowed to be incomplete on 2000 and newer gasoline powered vehicles? +/- 3 degrees What is the timing tolerance during an ignition timing functional test, if no manufacturers' spec is given? Verify the catalyst was installed prior to the rescission date. Is so, enter pass (P) for the catalyst visual inspection. If it is determined that is was installed after the rescission date, enter tamper (T for OIS) or modified (M for BAR97) for the catalyst visual inspection. If the E.O. for an aftermarket catalyst has been rescinded, what action should the technician take? Pinch-Point Locator What is the name of the program offered by BAR that shows locations for crimping the vapor canister hose during a LPFET? Every three days (72 hours) How often must the BAR97 EIS and the LPFET be calibrated? Ca Smog Check Inspector Training Final Review (Part 2) What constitutes a failure of the crankcase portion of the visible smoke test?

Diesel vehicles are not subject to __________ or _____________ inspections tailpipe, LPFET What action should be taken if it is determined that the underhood label does not match the engine? Determine if either the hood or engine has been changed. If it is determined that a hood has been replaced and the underhood label is missing or incorrect for the vehicle, what action should be taken? Consult the ECS manual to determine required equipment and timing settings.

What is the minimum amount a consumer must spend before they become eligible for a Repair Cost Waiver? $650 The Consumer Assistance Program will pay a maximum of __________ toward the cost of an eligible repair. $500, minus a $20 deductible During a functional test of the EGR system, the RPM does not change when vacuum is applied. What are some possible causes? Stuck EGR pintle, plugged EGR passage Prior to restraining the vehicle, what should the technician do? Center the vehicle on the dyno. If the technician attempts to access the BAR97 EIS to replace internal computer components, the 5-gas bench, or pumps, what will occur? The BAR 97 EIS will lock out, requiring a service call for repair. It is illegal for technician to access the internal portion of the machine? What is the maximum distance a shop/technician can lengthen or shorten a sample hose for the BAR97 EIS? The hose cannot be lengthened or shortened. Any modification or damage to the hose will require replacement. Under what condition can an inspector shift a manual transmission out of second gear during an ASM inspection? If the vehicle cannot maintain the appropriate vehicle speed and RPM. What entry should be made into the BAR97 EIS if the GVWR information for a light duty truck is illegible or missing? Enter NONE into the EIS. If a part is needed for repair and cannot be found locally, who should the customer contact to find the part? The Emission Parts Locator Service If a part is needed for repair and cannot be found through the Emission Parts Locator Service, what option is available to the customer? A limited parts exemption, good for two years. The customer must schedule an appointment with the BAR Referee to apply. After two years, another attempt to locate the part must be made. Where should you refer a customer if their vehicle does not have a VIN number? Refer to the DMV If the BAR97 EIS displays an HC Hang-up Error, what should the inspector do? Verify the Zero Air gas valve is open and the probe is not in the vehicle tailpipe. How is a MIL functional test performed? Turn the engine off, cycle the key to the "on" position. Verify the MIL illuminates. Start the engine. Verify the MIL goes out. A 2000 or newer gasoline powered vehicle is NOT equipped with OBD II. How should the inspector proceed? Used the BAR97 EIS to test the vehicle Which replacement catalysts do NOT require an executive order (E.O.) number? OEM replacement catalysts How should an inspector verify an aftermarket catalyst is approved for the vehicle being inspected. The inspector should compare the E.O. number etched on the catalyst to the ARB website to verify approval status. What should be used to verify vacuum routing during a visual inspection. The vacuum diagram label attached to the hood or a vacuum schematic found in the vehicles service information. What two sources may be used to determine which emission control systems a vehicle is equipped with? The vehicles Emission Control System (ECS) "underhood" label or and the vehicle emission control systems application guide. What is an additional source of information found on the vehicle that may be used to determine which components are used as part of an emission control system (i.e. thermostatic vacuum control valves or TVSV's used to control an EGR or EVAP system.) The vacuum diagram label attached to the hood or a vacuum schematic found in the vehicles service information. What is the term used for an engine that has been installed in a vehicle that was not offered for that year/make/model? An engine change What is the term used for an engine that has been installed in a vehicle that was offered for that year/make/model, but is not original to the vehicle being tested (i.e. the vehicle came with a V-6, but the V-8 that is now installed was offered as an option. All equipment for the V-8 engine is installed)? An engine replacement What is the term used for an engine that has been installed in a vehicle that is the same make, number of cylinders, and engine family (i.e. a Chevy 305 cubic inch engine is replaced with a Chevy 350 cubic inch engine. Both are "Small Block Chevy" motors. All the equipment for the original 305 must be used)? An engine replacement Identify two conditions in which a smog check is NOT required for transfer? Between immediate family members (parents, grandparents, siblings, spouses, etc.) or if the vehicle has had a biennial inspection within 90 days of transfer. If a fuel leak is noticed during the inspection, how should the inspector proceed? Abort the test During the inspection, the inspector finds the catalyst heat shield missing. What effect will this have on the results of the test? No effect. The heat shield is not part of the emission control system. Some early vehicles are equipped with service reminders for emission components such as the oxygen sensor or EGR. How will this affect the results of the inspection. These are considered maintenance reminders and have no bearing on the results of the inspection. CA Smog Check Inspector Training Final Review Part 1&2
