	Test Results Where Do I Find This?
	The test report information will vary with the type of test used.
	Test Type: The test procedure used to inspect the vehicle. Gasoline Vehicles: OBD II, TSI or ASM. Diesel Vehicles: DIESEL SNAP or DIESEL LOADED. Prescribed Type: This is the test procedure usually used to inspect this type of vehicle. Gasoline Vehicles Tests - OBDII, TSI or ASM OBDII Test: Checks the on-board diagnostic system (OBDII) built into 1996 and newer vehicles. Click here for information on OBDII and the OBDII Kiosks Overall OBDII Results: PASS or FAIL. A FAIL when the OBD system detects a problem with the vehicle. A removed or damaged connection to the vehicle’s OBD system is also a FAIL. Readiness Result: A PASS when all but two of the OBD monitors (one on 2001 or newer vehicles) have made their checks. If not, the vehicle needs to be driven until enough monitors have done their checks. Fault Code Result: PASS or FAIL. MIL Result: N/A (See next two MIL checks). MIL Engine Off: PASS, FAIL or N/A. A PASS when the Engine Check light or Malfunction Indicator Light (MIL) comes on when the ignition key is turned to the “key on engine off” position. On most vehicles, this light will stay on as long as the key is in this position. However, on some vehicles, the MIL will come on only briefly and then will go out. Your vehicle owner’s manual may have more information. Always N/A if a OBD kiosk was used. MIL Engine On: PASS or FAIL. If the check engine light is on while the engine is running the OBD system indicates that there is a problem with the vehicle. However if there is not a fault code found starting with a P0 the overall Test Results should be a PASS. Always N/A if a OBD kiosk was used. Misfire, Fuel System and Comprehensive Component monitors: Always Ready. Air Conditioning System: Always Not Supported. Catalyst, Heated Catalyst, Evaporative System, Secondary Air System, Oxygen Sensor, Oxygen Sensor Heater, and EGR System monitors: Ready, Not Ready or Not Supported. MIL Commanded On: Yes or No. Fault Codes: The fault codes of problems that need diagnosis by a repair technician.
	TSI Test: Measures exhaust emissions with the engine at 2500 rpm without a load and at idle. TSI TEST Sequence Number: Usually 1. Also 2 through 6 are possible. Overall TSI Result: PASS or FAIL. A vehicle with a properly operating engine and catalytic converter will have very low HC and CO readings. However as a vehicle ages the HC and CO emissions will increase and may become erratic. As a vehicle ages it becomes increasingly important to be sure that the engine and converter are fully warmed up before the test to have the best chance of passing the test. HC (PPM): The parts per million of hydrocarbons (unburned or partially burnt gasoline) in the exhaust. CO (%): The percentage of the exhaust that is carbon monoxide (CO). CO +CO2 (%): Complete combustion in the engine or catalytic converter will result in very little carbon monoxide (CO) and a high percentage (up to about 16%) of carbon dioxide (CO2) in the exhaust. O2 (%): When there is complete combustion in the engine or catalytic converter there is a very little oxygen (O2) in the exhaust. Usually less than one percent. A higher reading indicates a problem with the engine, the exhaust system, the sampling system or the catalytic converter. Vehicles do not pass or fail because of the O2 reading; it is only diagnostic information. RPM: The engine speed in revolutions per minute (RPM) or N/A. Cruise Limit: The maximum allowable HC and CO emissions at 2500 rpm. The CO+CO2 (%) must equal or exceed 6. This verifies an adequate sample of the exhaust has been obtained. N/A for O2 and RPM. Cruise Emissions: The emission readings measured at 2500 rpm. Cruise Result: PASS, FAIL or N/A. Idle Limit: The maximum allowable HC or CO emissions at idle. The CO+ CO2 (%) must equal or exceed 6. This verifies an adequate sample of the exhaust has been obtained. N/A for O2 and RPM. Idle Emissions: The readings measured at idle. Idle Result: PASS, FAIL or N/A.
	ASM Test: Measures exhaust emissions from the vehicle at 25 mph and at idle. Overall ASM Result: PASS or FAIL. A vehicle with a properly operating engine and catalytic converter will have very low HC and CO readings. However as a vehicle ages the HC and CO emissions will increase and may become erratic. As a vehicle ages it becomes increasingly important to be sure that the engine and converter are fully warmed up before the test to have the best chance of passing the test. Number of Restarts: The times the test was restarted. HC (PPM): The parts per million of hydrocarbons (unburned or partially burnt gasoline) in the exhaust. CO (%): The percentage of the exhaust that is carbon monoxide (CO). CO +CO2 (%): Complete combustion in the engine or catalytic converter will result in very little carbon monoxide (CO) and a high percentage (up to about 16%) of carbon dioxide (CO2) in the exhaust. O2 (%): When there is complete combustion in the engine or catalytic converter there is a very little oxygen (O2) in the exhaust. Usually less than one percent. A higher reading indicates a problem with the engine, the exhaust system, the sampling system or the catalytic converter. Vehicles do not pass or fail because of the O2 reading; it is only diagnostic information. RPM: The engine speed in revolutions per minute (RPM) or N/A. Cruise Limit: The maximum allowable HC or CO emissions at cruise. The CO+ CO2 reading must equal or exceed 6% to verify that an adequate sample of the exhaust has been sampled. N/A for O2 or RPM. Cruise Emissions: The emissions at 25 miles per hour. Cruise Result: PASS or FAIL. Idle Limit: The maximum allowable HC or CO emissions at idle. The CO+ CO2 reading must equal or exceed 6% to verify that an adequate sample of the exhaust has been sampled. N/A for O2 or RPM. Idle Emissions: The emission readings measured at idle. Idle Result: PASS, FAIL or N/A.
	Diesel Vehicles Tests - SNAP or LOADED DIESEL SNAP Test: The test used for heavy duty vehicles (>8500 GVWR) and cars and light trucks that can not be driven on the dynamometer. During this test the opacity of the exhaust pipe(s) emissions are measured while the throttle is depressed rapidly to a wide open position and immediately released. Overall Diesel Snap Result: PASS or FAIL. Number of Snaps: The number of times the opacity is measured while the throttle is depressed rapidly to a wide open position and released. Prior to the opacity meter being inserted into the exhaust pipe there will be at least three preliminary snaps that are not recorded. These snaps allow the vehicle operator to become familiar with the proper throttle movement and remove any loose soot in the exhaust pipe. Exhaust Pipe 1 Exhaust Pipe 2 If the vehicle has two exhaust pipes the opacity of the exhaust emissions are measured separately. Opacity Limit (%): The maximum allowable peak smoke level. N/A for Exhaust Pipe 2 if there is only one exhaust pipe. Opacity Reading (%): The highest opacity recorded during the test. The reading can range from 0 to 100%. N/A for Exhaust Pipe 2 if there is only one exhaust pipe. RPM: The engine speed when the opacity was recorded. 0 or N/A if the engine speed was not obtained. Opacity Result: Whether or not emissions from that exhaust pipe exceeds the opacity limit. If there are two exhaust pipes then both have to PASS for the Overall Diesel Snap Result to be a PASS.
	DIESEL LOADED Test: Measures the opacity of the exhaust at 25 mph. Overall Diesel Loaded Result: PASS or FAIL. Number of Restarts: The number of times the test was restarted due to vehicle or engine speed variations. Exhaust Pipe 1 Exhaust Pipe 2 If the vehicle has two exhaust pipes the opacity of the exhaust emissions are measured separately. Opacity Limit (%): The maximum allowable peak smoke level. N/A for Exhaust Pipe 2 if there is only one exhaust pipe. Opacity Reading (%): The highest opacity recorded during the test. The reading can range from 0 to 100%. N/A for Exhaust Pipe 2 if there is only one exhaust pipe. RPM: The engine speed when the opacity was recorded. 0 or N/A if the engine speed was not obtained. Opacity Result: Whether or not emissions from that exhaust pipe exceeds the opacity limit. If there are two exhaust pipes, both have to PASS for the Overall Diesel Loaded Result to be a PASS.
