Vehicles Subject to Emissions and
Safety Testing
• RI I/M Program requires the following vehicles pass an
emission and safety inspection every two years:
– All gasoline and diesel powered light duty passenger vehicles
and light duty trucks with a GVWR of 8,500 pounds or less .
– Vehicles 25 years old or older
• Must pass safety inspection and be emission tested but are not required to meet the
* New vehicles must be inspected within 2 years of the date of purchase
or when the vehicle accumulates 24,000 miles, whichever occurs first
Why Does RI Need an Emission
Inspection Program?
Proper maintenance of a car's engine and pollution control equipment is critical to reduce
excessive air pollution.
Motor Vehicles contribute 51% of man-made pollutants that contribute to the formation of
Breathing ozone can trigger a variety of health problems.
Reduction of ground level “bad” ozone protects our health.
EPA 8-hour ozone standard is designed to be protective of human health.
To help ensure that such maintenance occurs, the Clean Air Act requires certain areas with air
pollution problems to run inspection and maintenance (I/M) programs.
Emissions Reductions since 2000-2013
Since the I/M Program began in 2000, there has been a 31% reduction in emissions
as a result of the I/M Program.
During 2000 the average NOx reductions were only 38.50%.
During 2013 the average NOx reductions were 70%.

What is Ozone?
• Ozone is a gas composed of 3 oxygen atoms
• “Good” ozone is produced naturally in upperatmosphere where it protects the Earth from the sun’s
UV rays
• “Bad” ozone is formed at the Earth’s surface where it
causes health problems in humans and damage to plant
Why Does RI Need an Emission
Inspection Program?
The ozone layer in the upper atmosphere is beneficial, preventing
potentially damaging ultraviolet light from reaching the Earth's
Yes This IS A
Why Does RI Need an Emission
Inspection Program?
Why Is Ozone a Concern?
Breathing ozone is harmful to human health
•Irritates respiratory systems
•Aggravates asthma, emphysema and bronchitis
•Inflames and damages linings of lungs
People most susceptible include
•Those with respiratory illnesses,
•Older adults,
•Children who are active outdoors
• And Even Healthy adults
Why Does RI Need an Emission
Inspection Program?
How is ground-level Ozone (Smog) formed?
• Ground-level ozone is formed by a chemical reaction
between volatile organic compounds (VOCs) and oxides of
nitrogen (NOx) in the presence of sunlight. Ozone
concentrations can reach unhealthful levels when the
weather is hot and sunny with little or no wind.
Why Does RI Need an Emission
Inspection Program?
What is NOx ?
Nitrogen Oxides are a family of
poisonous, highly reactive gases. These
gases form when fuel is burned at high
temperatures. NOx pollution is emitted by
automobiles, trucks and various non-road
vehicles (e.g., construction equipment,
boats, etc.) as well as industrial sources
such as power plants, industrial boilers,
cement kilns, and turbines. NOx often
appears as a brownish gas. It is a strong
oxidizing agent and plays a major role in
the atmospheric reactions with volatile
organic compounds (VOC) that produce
ozone (smog) on hot summer days.
Why Does RI Need an Emission
Inspection Program?
What are Vehicle VOCs?
• Volatile organic compounds (VOCs) are emitted as gases from
certain solids or liquids. VOCs include a variety of chemicals, some
of which may have short- and long-term adverse health effects.
Sources of Vehicle VOCs include:
•Fuel Evaporation
–Fuel Supply Line Leaks
–Gas Cap Seal Leaks
–Evaporative Emissions System
•Vehicle Exhaust Product
•Incomplete Fuel Combustion

Ozone in Rhode Island
The Department of
Environmental Management
(DEM) provides a daily ozone
forecast from April through
September for all Rhode
When the ground-level ozone is
elevated to unhealthy levels, the
RIPTA buses and trolleys are
free to ride on those days.
The results of the forecast are
announced on the local news
channels and can also be found
on the DEM website:

that at least one time during the required inspection cycle a vehicle is inspected by qualified personnel to ascertain that the
vehicle is properly equipped for continued use. The inspector is not guaranteeing that any particular component will last
until the expiration of the inspection sticker, but rather that the components meet minimum standards at the time of the
inspection and the vehicle owner is maintaining the vehicle properly.

view of the video camera in the inspection
lane/bay to maintain program integrity.
• Videos may be reviewed for any test deemed
suspicious or under investigation by DMV
• Failure to comply may result in suspension of
Inspector and or Station license
Emission Testing Procedures
Inspector Login
All CITs are required to login and verify their identity by
means of the fingerprint reader
Bypassing the fingerprint reader may lead to CIT lockout
Bypassing the fingerprint reader will flag DMV
Repeatedly bypassing the fingerprint reader will lead to suspension
of password based access
Password Security
Your password is your electronic signature
Never share your password
Never leave your password written on or near the analyzer
Periodically review tests performed for familiarity
Tests may be reviewed from within the analyzer by selecting:
Utilities Menu > Document Printing > VIR Reprint
Passwords may be changed by contacting Opus
Inspectors will be held responsible for all tests performed under their name.
Emission Testing Procedures
Data Entry
Always make sure the data entered into the analyzer is correct. Verify that the
V.I.N., plate number and plate type entered match the vehicle and registration
exactly. Failure to do so may result in:
•Suspension of the vehicle registration
•Vehicles being towed
•Re-inspecting the vehicle at the stations expense
If the V.I.N. from the registration does not match the V.I.N. tag on the vehicle, do not proceed
with the test and refer customer to DMV to correct the issue prior to inspection.
Common mistakes:
•Not verifying V.I.N.s after electronically obtaining (i.e. door
changed, PCM changed etc.)
•Wrong plate numbers and or plate types entered
•Digit missed or extra digit in the V.I.N. entered
•(Most 1981 and newer vehicles will have 17 digits)
Emission Testing Procedures
Fuel Cap Test/Inspection
• Always perform visual inspection of fuel cap
All gasoline powered vehicles 1995 and older will receive a Gas Cap Pressure
Leak Test. The test will ensure the gas cap on the vehicle is capable of
properly sealing the gas tank allowing the vehicle’s evaporative emission
system to properly dispose fuel vapors. Missing or malfunctioning gas caps
will cause the vehicle to FAIL the emissions test
Fuel caps prevent vapors from leaking out of the gas tank that
would pollute the atmosphere, causing damage to the ozone.
Proper use of the gas cap also increases fuel economy by
effectively eliminating gas evaporation.
Emission Testing Procedures
Recording of Safety Inspection Results
• Record Safety Inspection Results by Category
• List all Defects Found
• List Defects Clearly within comments
Remember: Complete the Inspection!
Do not assume the vehicle will pass inspection if the MIL is not on!
When a vehicle is presented for inspection, the complete inspection
should always be performed regardless of M.I.L. status.
This provides a complete picture of all required repairs to the vehicle
Mechanical repairs needed
Emission related repairs needed
M.I.L. lamp malfunctions
Emission Testing Procedures
Perform MIL Bulb Check
Key On/Engine Off (KOEO)
•Turn the ignition to the run position but do not start the engine
•Check for illumination of the M.I.L.
•Inspectors must fail a vehicle during the bulb check test if the MIL does not illuminate with
the key in the on position and the engine is off.
What if the vehicle has a key FOB (Proximity Key)?
Some vehicles have a FOB that does not have to be
pressed to enter or drive the vehicle, this may make it
difficult to perform a “Bulb Test”
“Keyless Ignition” vehicles do have a means to
perform “Bulb Test” to check the MIL
Consult the owners manual for manufacturer’s
guidelines for performing bulb checks on these

Exhaust system defects that would cause
dilution errors, Space saver tire on drive axel,
Vehicles presented for inspection should be fully inspected
whenever possible.
Emission Inspection Program
The Clean Air Act of 1990 established the requirement that passenger vehicles be
equipped with on board diagnostics. The diagnostics system is designed to trigger a
dashboard "check engine" light alerting the driver of a possible pollution control
device malfunction. To help ensure that motorists respond to the "check engine" light
in a timely manner, the Act requires that I/M programs include an inspection of the on
board diagnostic system.
Prevent excessive emissions by identifying emissions control aspects that fail to
meet manufacturer established parameters and alerting the driver to the problem
Improve inspection and diagnostic processes by standardizing:
Component terms
Data Link Connector (DLC) location, shape and pin assignment
Diagnostic Trouble Codes (DTCs)

Readiness Monitors
What are readiness monitors? Monitors are testing exercises, performed by the PCM, which are very
carefully designed to indicate that all of the sensors within a portion of the engine management system are
working properly to minimize emissions. Each monitor is run by the PCM under very specific vehicle
operating conditions. Because of this, all monitors may not run each time the vehicle is driven. A given
monitor may not run for quite some time, until the exact combination of conditions occurs to trigger it. This
set of conditions is called the enabling criteria for the monitor and may include: operating temperature,
RPM, load, etc.
Types of Readiness Monitors
Continuous: These monitors run all the time as long as the key is turned on and/or the engine is running.
There are three continuous monitors that every OBDII equipped vehicle has, they are the Comprehensive
Component Monitor, The Fuel Monitor and the Misfire Monitor.
Non-Continuous: These monitors require certain conditions such as speed, acceleration/deceleration, fuel
level, ambient and other conditions to be met in order for the monitor to run its testing sequence. If the
specific conditions are not met, then the monitor will not perform its tests and cannot report as to whether
or not there are any problems. Non-continuous monitors include the Catalyst, Heated Catalyst,
Evaporative System, Secondary Air System, Air Conditioning (A/C) System, Oxygen (O2) Sensor, Heated
O2 Sensor and Exhaust Gas Recirculation (EGR) System.
Emission Inspection Program
Readiness Status
Readiness Status indicates if a monitor test has been run or not
This may be displayed as
Ready/Not Ready
Complete/Not Complete
Readiness Status does not indicate Pass or Fail - only that the test has been run
The OBDII emission test requires successful communication with vehicle’s OBD
The Inspector does not determine result
Vehicles will fail for communications during the initial test if:
The vehicle does not transmit the necessary information to the inspection equipment
after the analyzer completes the three OBDII data retrieval attempts
The analyzer reports failed communications
Pin 16 of the DLC is not powered
Emission Inspection Program
Readiness Monitor Descriptions
Below are the basic OBDII monitors and the components and subsystems that they monitor.
Remember, not all vehicles have all of these monitors. If a vehicle is not equipped with or not designed
to have a certain monitor, that monitor is “Unsupported.” Unsupported monitors do not affect the results
of the emissions inspection.
Misfire: This monitor looks for any engine misfires. A misfire is when the air/fuel mixture in the engine’s
cylinder does not ignite. This condition can cause damage to the vehicle’s engine and/or catalytic
converter. In the case of a severe misfire condition, the OBDII system will cause the Malfunction
Indicator Lamp to flash indicating a serious threat of damage to the catalytic converter. In the case of a
flashing Malfunction Indicator Lamp, the operator should reduce speed and seek diagnostic and repair
services as soon as possible.
Fuel System: This monitor constantly checks the amount of fuel that is used by the engine. Through
the use of an oxygen sensor(s), the OBDII system can determine if more or less fuel is needed. This
fuel adjustment is performed many times a second and helps to maximize fuel economy and minimizes
harmful emissions.
Comprehensive Component: This monitor is looking at all of the various switches and sensors that
are involved with engine management. It looks for voltage readings, resistance readings, and other
conditions. The monitor records readings from the vehicle’s components and compares them with
programmed values that reflect what the readings should be. If they differ by a certain amount, then
that component is determined to be suspect.
Catalyst (also know as catalytic converter): This monitor uses the readings from oxygen sensors
located before and after the catalyst(s) to determine the efficiency of the catalyst.
Heated Catalyst: Some vehicles may have an electrically heated catalyst. This heater helps warm up
a cold catalyst faster so that it can start working sooner which leads to earlier reduction of harmful
emissions. This monitor will check to make sure that the catalyst heater is working .
Emission Inspection Program
Readiness Monitor Descriptions
Evaporative System: This monitor works to ensure that the Evaporative System is kept in a condition
to minimize the release of gasoline vapors.
Secondary Air System: Some vehicles are equipped with a secondary air system, or air injection
system. The air injection system is designed to place extra oxygen into the exhaust stream to reduce
exhaust pollutants. This monitor checks the components, switches, and solenoids that are part of the
air injection system.
A/C (Air Conditioning) System: In some older vehicles, this monitor was intended to monitor the
vehicle’s air conditioning system if it had the older “R-12” style of refrigerant. Since R-12 is harmful to
the ozone layer of the earth’s atmosphere, a leaking air conditioning system needed to be repaired as
soon as possible. Several years ago, R-12 was banned from use; therefore, this monitor will show up
as “Unsupported” on most newer vehicles.
O2 (Oxygen) Sensor: The O2 Sensor Monitor watches for the performance of the vehicle’s oxygen
sensors. Oxygen sensors are used to fine tune the amount of fuel that is used by the engine. These
adjustments are made several times a second and have a direct impact on fuel economy and
emissions reductions. When an oxygen sensor goes bad, the vehicle will usually begin to use more fuel
than it needs to, thereby increasing the amount of harmful emissions.
Heated O2 (Oxygen) Sensor: Some oxygen sensors include an electric heater to help them warm up
quicker and to begin operating faster. This monitor ensures that the heater circuit of the oxygen sensor
is working properly. Since not all vehicles have a heated oxygen sensor, some vehicles will show this
monitor as “Unsupported.”
EGR (Exhaust Gas Recirculation) System: Many vehicles are equipped with an EGR system. This
emissions control system is designed to reduce nitric oxide tailpipe emissions by reducing the
temperature inside the engine’s combustion chamber. This monitor checks the components of the EGR
system to ensure that it is working properly and that there is sufficient flow of exhaust gas through the
Emission Inspection Program
Readiness Monitors Failures
Vehicles will fail for readiness if:
More than 2 monitors are ‘Not Ready’ on 1996 - 2000 model year vehicles
More than 1 monitor is ‘Not Ready’ on 2001 and newer model year vehicles
The Readiness Indicators will all be set to “Not Ready” if the DTC’s are erased or by loss of battery power
Common causes of “Not Ready” Monitors:
DTCs erased - Battery Replacement - Blown Fuse to PCM - Battery disconnected for vehicle service
Setting Readiness Monitors
The purpose of completing an OBD II drive cycle is to force the vehicle to run its onboard diagnostics. Some form of a drive
cycle needs to be performed after DTCs have been erased from the PCM’s memory or after the battery has been disconnected.
Running through a vehicle’s complete drive cycle will “set” the readiness monitors so that the vehicle will pass inspection or
faults can be detected.
Drive cycles vary depending on the vehicle and the monitor that needs to be re-set. Whenever possible, follow the drive trace
prescribed for the specific vehicle/monitor in question. Some vehicle-specific drive cycles can be found in the vehicle’s
service manual.
It is the vehicle owner’s responsibility to set the Monitors
It is not part of the Emission Test procedure
The vehicle is tested as received
Emission Inspection Program
Generic Drive Cycle
Although Drive cycles vary slightly among manufacturers, the following
generic drive cycle can be used in most cases:
This generic OBDII drive cycle begins with a cold start (coolant temperature below 122
degrees F and the coolant and air temperature sensors within 11 degrees of one
another). This condition can be achieved by allowing the vehicle to “sit” overnight, and
then by beginning the drive cycle the next day. Most drive cycles will be difficult to follow
exactly under normal driving conditions, so the driver should exercise caution, road
safety, and courtesy to others.
Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear
defroster on.
Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.
Hold at a steady speed of 55 mph for three minutes.
Decelerate (coast down) to 20 mph without braking or depressing the clutch.
Accelerate back to 55 to 60 mph at ¾ throttle.
Hold at a steady speed of 55 to 60 mph for five minutes.
Decelerate (coast down) to a stop without braking.
Emission Inspection Program
Drive Cycle Problems
If the MIL illuminates while trying to run the Monitors, it means a
code has set and a repair is necessary prior to passing inspection.
If the Monitors will not run;
– Check TSB’s
– Follow the “Enabling Criteria” for the Monitor that will not run.
– Obtain specific Drive Cycle information and follow it.
Readiness Exception Vehicles
Vehicles that are on the readiness exception list
Maintained EPA will be forced into a tailpipe emissions test.
– Analyzer will invoke the Dyne/TSI prompt and request that the inspector
perform a tailpipe emissions test
– Initial test and / or retest
– Example = 1996 Chrysler Cirrus 2.4
– EPA maintains the list of these vehicles
Emission Inspection Program
OBD Bypass Authorization
Inspectors may request state approval to retest a vehicle with monitors not ready
using a tailpipe emissions test when all reasonable methods to set the monitors
have been exhausted including:
•Proper drive cycle having been performed
•All enabling criteria having been met
•The vehicle has been driven for a sufficient time period and distance to set the
•No DTCs are present
State approval must be received prior to performing the test. Contact the
safety and emission control office at (401) 462-5890

Diagnostic Trouble Codes
Vehicles fail the DTC test if:
– The OBD system has stored at least one (1) mature (nonpending, non-historic) DTC that commands the MIL to be
– The vehicle commands the MIL to be illuminated but the OBD
system has no mature DTCs stored in the system
DTC Identification
– OBD II codes (emissions related) are found in the PCM and will start
with a “P” (Power train Control Module)
– Codes that start with a “U” prefix are communication codes
– They can indicate a problem with code and data transmission on the
DLC (data link connector)

One of the goals of the Emissions & Safety inspection program is to ensure that the vehicles operating on the
Rhode Island roadways are safe and environmentally clean. Fraudulent emission inspections undermine these
goals, and defames the integrity of the stations that conduct fair and honest inspections and will not be
In a constant effort to support the integrity of the Safety and Emissions inspection program, the DMV and
Opus Inspection work together to ensure that vehicles are being properly inspected and repaired. Please be
aware that compliance is vigorously enforced through:
•Routine enhanced inspection data monitoring
•Covert vehicle audits
•Challenge inspections
•Road checks
•Complaint investigations
Violators will be caught, and upon conviction, subjected to fines, suspensions, and or revocations. Those
convicted of federal statutes, such as the Clean Air Act, risk prison time and fines that can run into hundreds of
thousands of dollars.
The Rhode Island Safety and Emission Inspection Laws, regulations, and procedures are intended to provide
for clean air and a safe roadway for everyone and are expected to be carried out and enforced by all
inspectors. If an issue cannot be clarified by referring to the RI Official Manual for Vehicle Inspection, please
remember that a DMV Inspector may be reached during normal office hours at 401-462-5890.
Emission Inspection Program
The technician's responsibility of accurate and honest inspections and repairs, make
it possible to accomplish our goals of safety and improve air quality for the State of
Rhode Island.
The I/M Program has shown significant emissions reductions since the program was
implemented in 2000. By reducing emissions, we have helped people at risk from the
negative health consequences of ground level ozone.
Remember as a technician, you are required to complete the inspector re-certification
training every two years. Opus will notify you on your two year anniversary of your
last test.
Remember if at any time during the inspection, you are in doubt; refer to the RI
Official Manual for Vehicle Inspection which is located on the inspection machine or
the DMV website www.dem.ri.gov. Also a copy can be obtained from the Safety and
Emissions Control Office (462-5890)
