How many readiness monitors have to be complete to pass smog?

This continues to be number one on the hit parade. Nobody wants to hear the dreaded words, OBD II not ready.

1996 to 1999 Gasoline powered vehicles: Any one monitor can be incomplete.

2000 and newer Gasoline powered vehicles: All monitors, with the exception of the EVAP monitor must be complete.

1998 to 2006 OBD II certified diesel powered vehicles: All monitors must be complete.

2007 and newer OBD II certified diesel powered vehicles: Any two monitors can be incomplete.

What if I cannot get my smog test in California before it is due?

Pay your fees!

Even if you do not pass smog, you can avoid paying late fees by paying all registration fees on time. While the DMV will not issue a registration renewal until all requirements, including the smog certification, are complete, the DMV will stop assessing further late fees upon receipt of your payment.

You may also be eligible for a temporary moving permit. Contact the California DMV for more information.

Can I go to another smog station after failing?

Absolutely! Many people are under the mistaken impression that they have to return to the original smog shop to finish the smog inspection after failing. Not true. Pass or fail, that smog inspection ended when you received the results. It’s done. You are free to have the vehicle inspected at any shop.

Of course, if the vehicle requires an inspection at a STAR certified shop, you must take it to a STAR station.

Also, it important to note that if the shop that inspected your vehicle promised you a free retest, or any other discounts, those promises only apply at the shop that made the offer.

The shop that failed my car also does repairs, can I go someplace else for repairs?

Again, absolutely. Shops performing emissions repairs in the State of California are required to be licensed by the Bureau of Automotive Repairs; however, you are not obligated to have your vehicle repaired by the shop that performed the smog inspection.

A relative gave me a car, do I need a smog inspection?

If you acquire a vehicle that is currently registered in California from a spouse, domestic partner, sibling, child, parent, grandparent, or grandchild, you are entitled to an exemption from the smog inspection. Other family members or relations are not exempt and are required to obtain a smog inspection certification.

For more information read “Transfer a Vehicle Between Family Members.”

www.dmv.ca.gov

If my car check engine light doesn’t turn on at all will I pass smog?

No, if the check engine light (Service Engine Soon, MIL, etc), is burned out, missing, disconnected, or not functioning normally for any reason, the vehicle will not pass the California smog inspection.

If you fail OBD II on a smog check, should your overall smog fail?

If a vehicle fails any part of a smog inspection the state’s software will not certify the vehicle. In other words, the vehicle will fail.

As a matter of fact, if the check engine light isn’t on, the technician inspecting your car won’t know your car failed until the test is over.

Where can I get a STAR smog inspection in Huntington Beach?

Huntington Beach, Newport Beach, Fountain Valley, and beyond, the choice is simple! For any and all smog inspections, booking an appointment at Just Smogs® in Huntington Beach will be the best smog inspection decision you’ll ever make.

OBD II Monitor Drive Cycle Service

Posted on December 13, 2016 by MasterTech

In recent years the California Bureau of Automotive Repairs (BAR) and the California Air Resource Board (CARB) have increasingly shifted the emphasis of the California emissions program to on-board diagnostic trouble codes & monitor readiness. This is especially true for 2000 and newer model year vehicles.

If you are having trouble completing OBD II readiness monitors on your 1996 or newer vehicle, the licensed professionals at Just Smogs® in Huntington Beach can help.

OBD II Monitor Recap

What are OBD II readiness monitors?

The short answer is that OBD II readiness monitors are usually something that average motorists never have to worry about until they have a reason to worry.

OBD II readiness monitors are self tests run by a vehicle’s on board diagnostic system. OBD II monitors have two states: ‘ready’ and ‘not ready’. Some scanners and code readers may display ‘complete’ , ‘incomplete’ , comp, inc, etc. It all comes down to whether or not a test has been run to completion.

When one of these test fails, the check engine light is illuminated; otherwise, a driver normally has no indication that OBD II readiness monitors exist.

So what’s the problem?

It’s not uncommon for OBD II readiness monitors to be reset following repairs. This is especially true if the check engine light was on.

If a vehicle’s power train control module (PCM – ‘The Computer’) loses power due to a dead or depleted battery, or if diagnostic trouble codes are cleared using a scan tool, all readiness monitors are automatically set to incomplete/not ready.

Incomplete readiness monitors aren’t something that you have to worry about unless your vehicle is due for a smog inspection.

Readiness monitors are run in the background and by design do not affect driveability, safety, or fuel economy, but they are an important part of the California smog inspection program.

In order for a vehicle to pass a smog inspection in the state of California, most OBD 2 monitors must be run to completion. For example, in order for most 2000 and newer gasoline powered vehicles to pass the smog inspection all monitors with the exception of the evap monitor must be complete. If any monitor other than the evap monitor is incomplete the vehicle will fail the smog inspection.

If you’ve ever had an issue with OBD II readiness monitors, you’ve probably heard the phrase, “Drive it fifty to one-hundred miles and you should be fine”.

I drove my car hundreds of miles, and it still isn’t ready!

Some cars are known to have issues that can make completing OBD II readiness monitors extremely difficult.

BAR maintains a list of such vehicles and possible solutions (The Smog Check OBD II Reference).

Very often the solution involves following a very specific drive pattern that some motorists find difficult to complete during their normal driving routine. That’s when Just Smogs® can help.

Just Smogs® OBD II Drive Cycle Service

If your vehicle is otherwise in good repair, and you are having difficulties completing the OBD II drive cycle, the professionals at Just Smogs® can complete the drive cycle on most vehicles that do not require further repair or diagnosis.

This service offering does not include any diagnostics or repairs that may be necessary to enable the OBD II drive cycle, nor does it include diagnostics or repairs that may become necessary should the drive cycle trigger a diagnostic trouble code or check engine light.

Of course in most cases you should be able to complete the drive cycle yourself with no more effort than a Sunday drive, but in case you can’t, the professionals at Just Smogs® are here to help.

If your 2007 Toyota Highlander Hybrid fails to pass the California emissions test because of an incomplete oxygen sensor (air/fuel) monitor, your Toyota Highlander Hybrid may be subject to a recall.

Affected vehicles will require a software update to correct an issue that prevents the vehicle’s on board diagnostic computer from running the O2 sensor monitor to completion. Per Toyota Special Service Campaign FOP and TSB #0042-15, this service will be performed on affected vehicles at no charge to the consumer.

Your Toyota dealer will identify affected vehicles based on manufacture date, software calibration, etc. When contacting your Toyota dealer, please reference TSB #0042-15.

BMW OBD II Communication and Monitor Issues

Posted on November 26, 2016 by MasterTech

As touched upon in a previous post (Smog Check OBD Reference Update) certain 1999 and 2000 model year BMW vehicles with 2.5 liter and 2.8 liter displacement engines that are having trouble passing the smog inspection due to incomplete monitors may be subject to a voluntary emissions recall (00E-A01: Fault Access/O2 Readiness Codes).

Model		Manufactured
E39	528i, 528iA, 528iT, 528iAT	2/99-7/99
E46	328i, 328iA, 323i, 323iA	3/98-7/99
E46	328iC, 328iCA, 323iC, 323iCA	2/99-7/99
E36/7	Z3 coupe 2.8	4/99-7/99
E36/7	Z3 roadster 2.8	4/99-7/99
E36/7	Z3 roadster 2.3	9/98-7/99

BMW has determined that certain 1999 & 2000 model year BMW automobiles with 2.5 liter and 2.8 liter displacement engines may not fully meet Federal Environmental Protection Agency (EPA) and California Air Resources Board on-board diagnostic requirements.

There are two issues:

Due to an engine control module software error, a communication conflict exists between the engine control module (“The Computer”) and the transmission control module (“The other Computer”). This may lead to difficulties or prevent communication and data transmission between the engine control module and and diagnostic equipment (Including the “Smog Machine”).
The oxygen sensor readiness monitor may not run to completion on affected E36/7, E46 and E39 vehicles.

Owners of affected vehicles should have received a letter from BMW as early as November 2000; however if you own one of these affected vehicles and are having trouble receiving California smog certification due to incomplete monitors or communications issues (Or are due for a smog inspection) and have not completed the recall, you should contact your BMW dealer. It may help to refer to Emissions Recall 00E-A01 and BMW Bulletin SI B 12 15 99.

Engine Change Guidelines

Posted on October 17, 2016 by MasterTech

According to the California Bureau of Automotive Repair (BAR), “Engine changes continue to present problems and challenges to car owners and technicians“.

Instead of an engine change (a.k.a swap), BAR recommends rebuilding and reinstalling the original engine, transmission, and emissions configuration. However, if that is not possible, the following is a list of things to keep in mind.

Remember, these are guidelines for performing engine changes – not certification procedures. All exhaust emission controlled vehicles with engine changes must be inspected by an official Referee station and must have a Bureau of Automotive Repair (BAR) Referee label affixed to the doorpost.

Certification Standards

California Certification

A federal (49 state) engine cannot be used in a California certified vehicle.

You can determine if your vehicle is a California certified vehicle by checking the vehicle’s under-hood emissions label.

Japanese Domestic Market (JDM) Engines

While especially popular with Honda enthusiasts JDM engines are not a legal option. JDM engines are easily identified and will not be certified by the BAR Referee.

Certification Standards

Make sure the engine and emission control configuration is certified to the year of the vehicle or newer, and to the same or a more stringent new vehicle certification standard. The rule of thumb is that you can move forward but you can’t go backwards.

Engine Classification

You can’t put this in Lamborghini engine in your pickup truck unless you’re hauling it in the back.

Don’t mix engine and vehicle classifications which will degrade the emissions certification standards.

A heavy-duty engine cannot be installed in a light-duty exhaust-controlled chassis even if they have the same displacement.
A Pickup truck engine cannot be installed in a passenger car.
Non-emissions controlled engines such as industrial or off-road-use-only engines may not be placed in any exhaust emissions controlled vehicle.

Computer Controls

If a computer controlled engine is installed in a non-computer controlled vehicle, the “Check Engine Light” (Service Engine Soon, MIL, etc), diagnostic link connector (DLC), wiring harness, and all sensor and switches necessary to make the system fully operational must also be installed.

Also, the same rule would apply if you are installing an On Board Diagnostic II engine in a vehicle previously certified to earlier standards (OBD I etc). Remember, you can add, but you can’t subtract.

Emissions Control Configuration

Mixing and matching emission control system components could cause problems and is generally not allowed. Engine and emission control systems must be in an engine-chassis configuration certified by the California Air Resources Board (ARB) or U.S. Environmental Protection Agency (EPA). The engine must meet or exceed the requirements for the year and class of vehicle in which it is installed.

California Bureau of Automotive Repair

Vehicles introduced for sale in California and elsewhere in the United States are subject to strict testing and emissions certification standards. Even a minor change can result in the increased harmful gas emissions, and violate state and federal law.

The installed engine and host chassis must retain all original emission control equipment. Diesel-to-gasoline conversions must have all gasoline engine and chassis emission control systems installed (Fill-pipe restrictor, EVAP system, etc).

Engine Modification and After-Market Parts

No internal or external engine modifications (cams, pistons, intakes, etc.) may be performed unless the parts are ARB-exempted or EPA-certified for use in the installed engine. Refer to ARB’s Aftermarket Parts Database of Executive Orders to search for exempted aftermarket parts.

BAR OIS Testing And Invalid Monitor Information

Posted on August 15, 2016 by MasterTech

On August 1, 20016, the Bureau of Automotive Repair (BAR) implemented a change in the BAR-OIS testing procedure that may result in a new type of smog inspection failure.

What is BAR-OIS testing?

The BAR-OIS is the Smog Check equipment required when inspecting most model-year 2000 and newer gasoline and hybrid vehicles and most 1998 and newer diesel vehicles. The system consists of a certified Data Acquisition Device (DAD) and off the shelf equipment, including a computer, bar code scanner, and printer.

During a BAR-OIS smog inspection, the DAD collects data from your vehicle’s Power train Control Module (PCM), or as most people call it, “The Computer”.

The data collected by the DAD includes diagnostic trouble code information (Mode $03), Vehicle Information (Mode $09), and the current monitor information from Mode $01. Other data is also collected, but for the purpose of this article, we’ll focus on Mode $01 monitor information.

OBD II Monitor Readiness

OBD II Monitor Readiness is a key element of the BAR-OIS smog inspection process.

Most model year 2000 and newer gasoline powered and hybrid vehicles can pass the BAR-OIS inspection if EVAP is the only incomplete monitor; otherwise, all other OBD II monitors must be complete.

While most vehicles behave as expected, some vehicles do not respond with proper OBD monitor information from the PCM, or the transmission computer responds instead of the engine computer.

In most cases cycling the vehicle’s ignition (off/on) will solve the problem, but occasionally the vehicle will continue to respond with invalid or no data.

Prior to August 1, 2016, a vehicle could pass the BAR-OIS inspection if this condition continued; however, that is no longer the case.

What has changed?

Effective August 1, 2016, if a vehicle continues to respond with improper OBD II monitor information, the vehicle will fail the inspection.

If a vehicle in the following list fails for invalid OBD II monitor information, it should be referred to the BAR Referee. Vehicles not included in the list will most likely require repairs.

Check OBD II Monitor Readiness Without A Scan Tool

Posted on August 4, 2016 by MasterTech

It is possible to check OBD II monitor readiness on many late model vehicles without connecting a scan tool. This can often be necessary in order to determine if your car is ready for its California smog inspection.

What is OBD II monitor readiness?

On 1996 and newer model year vehicles, the on board diagnostic system (OBDII) performs up to eleven diagnostic checks of vehicle emission control systems. These checks are performed in the background during normal driving and are designed not to interfere with vehicle performance or safety.

If a fault is detected, the power train control module (PCM – The computer) illuminates the malfunction indicator light (MIL – Check Engine – Service Vehicle Soon).

If the PCM loses power for any reason (Including a disconnected or depleted battery), or if diagnostic trouble codes are cleared using a diagnostic scan tool, readiness monitors will indicate an incomplete, or not ready, status.

In most cases, a vehicle with incomplete readiness monitors will not pass the California smog inspection (See New Readiness Monitor Standards For OBD II Functional Inspection).

Driving the vehicle under conditions that meet the monitor enabling criteria should complete most OBD II monitors. This is usually accomplished after fifty to one-hundred miles of normal driving.

How to check monitors without a scan tool

In most cases, the correct procedure is outlined in your vehicle’s owner’s manual. Consult your owner’s manual for information specific to the car you drive.

However, the following procedures are presented as examples. They may not apply to your specific vehicle.

Ford/Lincoln/Mercury Vehicles

To determine if readiness OBD II monitors are complete:

Turn the ignition key to the “on” position for 15 seconds without cranking the engine.
If the “Service Engine Soon” light blinks eight times, one or more readiness monitors are incomplete.
If the service engine soon indicator stays on solid, all readiness monitors are complete.

This procedure was included in the Owner’s Manual for a 2012 Ford Focus. This same procedure may apply to other models and model year Ford/Lincoln/Mercury vehicles.

For Jeep, Chrysler and Dodge

The owner’s manual states that the vehicle has a simple ignition key actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD II system is ready, you must do the following:

Turn the ignition switch to the “ON” position, but do not crank or start the engine. If you crank or start the engine, you will have to start this test over.
As soon as you turn the ignition switch to the ON position, you will see the MIL (Check Engine Light) symbol come on as part of a normal bulb check.
Approximately 15 seconds later, one of two things will happen:
1. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is not ready and you should not proceed to the smog check station.
2. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is ready and you can proceed to the smog check station.

Honda/Acura

To check if the readiness codes are set, turn the ignition switch to the ON (II) position, without starting the engine. The MIL will come on for 20 seconds. If it then goes off, the readiness monitors are set. If it blinks five times, the readiness monitors are not set.

Check Engine Light: P0420 – Catalyst Efficiency Below Threshold Bank 1

Posted on August 1, 2016 by dewok

HELP, my check engine light is on because of a P0420 fault code.

The P0420 code means that the vehicle’s computer has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). This does not necessarily mean that you have to replace the catalytic converter to fix the problem. Replacing the oxygen (O2) sensors may sometimes fix the code because the vehicle’s computer interprets data from the oxygen sensors to determine if the catalytic converter is working properly.

If the catalytic converter is in fact defective, you must replace it with either a factory (OEM) converter or a California Air Resource Board (CARB) approved aftermarket converter. Be sure that the aftermarket converter is the correct part by confirming:

Year/Make/Model/Engine Size
Test Group Name or Engine Family Number *
Manufacturer Part Number
Executive Order Number
Converter Location

* Exception: Federally certified vehicles (Non-California) may not have a matching Test Group/Engine Family number listed on the Aftermarket Catalytic Converter Database. So as long as all other criteria matches, the converter should be approved for the application.

If there are no options listed for your vehicle application on the Aftermarket Catalytic Converter Database, an OEM converter is required.

Many mechanic & muffler shops mistakenly install incorrect converters. If you are unsure, feel free to contact us with any questions.

** This information is accurate as of July 2016. For the most up-to-date rules and regulations, please contact the California Air Resource Board.

Mercedes Drive Cycle for Incomplete Readiness (Failed Smog Check)

Posted on June 24, 2016 by dewok

Many drivers have had difficulty completing readiness monitors for their Mercedes Benz. The two readiness monitors that seem to be the most stubborn to complete are: Secondary Air Injection and Catalyst (Catalytic Converter). We located a Mercedes Benz Service Bulletin (S-B-14.00/17) that may be helpful.

Also, one customer with a 2002 Mercedes was unable to complete the secondary air injection monitor until one evening he allowed his vehicle to idle for 5-20 minutes in his driveway. He then turned off his vehicle and restarted the vehicle the next morning and allowed it to idle for another 5-10 minutes. He stated that this procedure completed the AIR readiness monitor.

UPDATE:
Our customer had a stubborn CATALYST MONITOR on his 2002 Benz. He had already driven hundreds of miles and still the catalyst monitor was incomplete. The following drive cycle did the trick:

CATALYST MONITOR DRIVE CYCLE

Vehicle warm up
A/C Off

C. Drive Cycle Test Procedure
Note:
Refer to Service Information: P-SI-14.00/14 for historical information.
A. Description of State I/M OBDII Checks & Drive Cycle
Certain States around the country have or will begin to roll-out in the coming months, OBDII (On-Board
Diagnostic II) quick checks for emission inspection and maintenance (I/M) testing. The emission I/M testing
is required for customers to register their vehicles. These State I/M facilities will specifically look for whether
or not the vehicle’s OBDII system is “ready” to be tested. The OBDII system uses readiness codes built into
the vehicles computer to indicate if the system is “ready” to be emission tested. These State I/M Facilities
use hand held scan tools capable of reading OBDII codes and will indicate if these readiness codes are set
or not.
These readiness codes are needed to be set (complete) within the OBDII computer system. Without these
codes set, the vehicle will most likely fail the emissions portion of this inspection and the customer will not
be able to register or re-register their vehicle. In an effort to prevent this situation from happening, a specific
drive cycle must be performed prior to the vehicle being tested at any I/M facility checking the OBDII
system.
2 S-B-14.00/17 February 2004
If a model year 1996 through 1999 vehicle has “failed” a State I/M emission test and no faults have been
found in the system (i.e. check engine light NOT on) then a drive cycle test must be performed on the
vehicle.
Note:
A battery disconnect to service the vehicle can impact whether the readiness codes will be set, if the
vehicle is immediately taken from the service facility to an I/M testing facility for vehicle registration
purposes. In such a case, the customer should be notified and instructed not to take the vehicle
immediately to an I/M station for emission testing.
Note:
Cycling the ignition key from on – to – off prior to performing the I/M test is not recommended.

Drive Cycle Test Procedure Explained
1. 02 Sensor Heater Diagnostics (do not interrupt this portion of the test):
With the engine warm (greater than 80 degrees C), and the transmission gearshift lever in Park
position, proceed as follows:
• Start engine and increase engine speed to between 2,000 to 2,500 RPM for 2 minutes.
• After the 2 minutes, run engine at idle speed, with no applied load for 6 minutes (Air
conditioning OFF, no throttle movements etc).
• After this time period has been obtained proceed to step 2 below.
Note:
If using a Hand-Held Scan Tool verify Step 1 test completion. This will be indicated by a check mark in the
display field or the word PASS.
2. Lambda (02) Sensor Signal (do not interrupt this portion of the test, to be conducted directly after
step 1 above has been performed):
With engine temp greater than 80 degrees C, and with transmission gearshift lever in position D,
• Drive vehicle for 3 minutes at 70km/h (43 mph).
• After the 3 minutes has been reached proceed to step 3 below.
Note:
If using a Hand-Held Scan Tool verify Step 2 test completion. This will be indicated by a check mark in the
display field or the word PASS.
3. Catalytic Converter Efficiency Diagnostics (do not interrupt this portion of the test and must be
conducted directly after step 2 above has been performed):

With engine temp greater than 80 degrees C:
4 S-B-14.00/17 February 2004
• Drive vehicle with transmission still in position D for 3 minutes at 80-90 km/h (48-54 mph).
Note:
If using a Hand-Held Scan Tool verify Step 3 test completion. This will be indicated by a check mark in the
display field or the word PASS
4. Self-adjustment of the air/fuel mixture (idle speed & self adaptation) (do not interrupt this
portion of the test and must be conducted directly after step 3 has been performed):
With engine temp greater than 80 degrees C, proceed as follows:
• Place transmission gearshift lever into Park position and allow engine to idle (with no load
applied to the vehicle, i.e. Air conditioning OFF) for 3 minutes.
Note:
If using a Hand-Held Scan Tool verify Step 4 test completion. This will be indicated by a check mark in the
display field or the word PASS
5. EGR System (Emission Vacuum Diagnostics): No DTC codes should stored for the intake
manifold pressure sensor and EGR pressure transducer during this portion of the test. With the
engine temperature at 80 degrees C:

• Start and Drive vehicle (in D position) and then accelerate smoothly up to 2000 rpm, and
then decelerate smoothly back down to 1100 rpm.
Note:
If using a Hand Held Scan Tool to verify test completion. This will be indicated by a check mark in the
display field or the word PASS
• After this test step has been completed, turn ignition OFF, wait 10 seconds and repeat this
test step (5.) again.
6. Air Injection Diagnostics: (do not interrupt this test when performing this test step 6).
Note:
First: Place a suitable auxiliary fan in front of the vehicle to force engine cool down. (Engine cool down can
also be simulated by using a decade box to simulate engine cool down).
Continue test step: With engine temperature less than 40 degrees C, the air conditioning OFF and the
transmission gearshift lever in Park position; and auxiliary fan removed from front of vehicle,

• Start engine and accelerate engine speed to 1400 rpm.
• Allow engine to run at this increased rpm until coolant temperature reaches between 70 to
106 degrees C.
• Allow engine to run with increased rpms for 7 minutes (or drive the vehicle for 7 minutes).
• After the 7 minute time period has been reached, stop the vehicle, place gearshift lever into
Park position and allow engine to idle (with no load) for 6 seconds. Do not use A/C.
• After this step turn the ignition OFF, wait ten seconds and repeat this test step.
• Note that when testing the air injection system, the engine coolant temperature must be at
the same temperature (degrees) as when before the ignition key was switched off in the
prior test step.
Note:
If using a Hand-Held Scan Tool to verify Step 6 test completion. This will be indicated by a check mark in
the display field or the word PASS
S-B-14.00/17 February 2004 5
7. Fuel System Leak test (EVAP): No DTC codes should be present in memory for the EVAP
canister purge valve, fuel tank pressure sensor, or the shut-off valve.
Note:
