1/ What is OBD, and what are its benefits?
OBD stands for “on-board diagnostics,” a computer-based system built into all model year (MY) 1996 and newer light-duty cars and trucks. OBD monitors the performance of some of the engines’ major components, including individual emission controls. The system provides owners with an early warning of malfunctions by way of a dashboard “Check Engine” light (also known as a Malfunction Indicator Light or MIL, for short). By giving vehicle owners this early warning, OBD protects not only the environment but also consumers, identifying minor problems before they become major repair bills.
2/ Why do we need an OBD scan tool?
In the past, the problem of emissions arising from motor vehicle use seemed to spiral beyond the control of most governments. The on board diagnostics OBD was found to be the only way through which the drivers can be able to monitor the performance of their cars on the road, thus avoiding the prevalence of un-roadworthy vehicles plying the road.
OBD scan tools have played an important role in this respect with its regulation being underpinned in the United States under the environmental protection act (EPA). With the protection of the environment as one reason, failing to have it is a breach of law in most states in the United States.
In addition, having the OBD scan tool is good fort the driver because it allows him avoid cases of accidents which can be fatal. OBD scan tool use has also been seen to be one of the most vital financials aspects of the car use. It has tremendously helped cut the amount of money and time spent by both the motorists and the mechanics in car repair. This is because most if them can clearly pinpoint the area of car fault and give suggestions on the solutions to be undertaken thereof.
3/ What is Check Engine light?
The on board diagnostic scan machines are made to work with some special features that are meant to give the car user the ability to know the problem in your car, the malfunction indicator light (MIL) is the most common feature. This indicator is a form of light set on the OBD scan tool to flicker whenever the car emission scan system detects that there is a problem in any of the car systems.
Depending on what the problem is, the check engine light function is not a constant and shows diverse faults on the car, some of which may be minor while some may be too serious to ground the car.
4/ What problems can OBD scanners detect?
Most of the car diagnostic scanners are different in scope. The diversity of the code coverage and the compatibility makes the diagnostic scanners to be some of the most interesting tools to have. The OBD 2 scanners for instance are meant to cover all the aspects the entail to car use ranging from the fuel , temperature, pressure, and the other aspects of car engine however, the diagnostic scans which are more advanced cover even the vehicle information aspects, the test drive information and the car repair state reporting functions.
5/ Does my vehicle have OBD-II?
Depending on which brand whether the new or old and where you live, all cars made and used in the united states are installed with the OBD II device in conformity with the legal requirements container in the EPA.
Knowing whether the car has an OBD II scan tool is easy. In the old model, the diagnostic scanners were installed on the car dashboard and could just be seen as the driver goes on with his thing. Not anymore with the new car models.
These have the OBD II scan tool placed somewhere below the driver’s seat. Checking on this by pulling the driver’s seat up may give the driver an idea whether the car is installed with a diagnostic car scan tool. Visiting a mechanic however can help dispel further trouble whether the car has one or not.
6/ How does the OBD2 system work on your vehicle?
Under the automotive emission regulations set out in the environmental protection act (EPA), the OBD 2 is a standard device which is mean t to help motorists pinpoint the diverse areas of fault found on the car.
Unlike the old OBD, which was manufacturer specific, the OBD 2 is an electronic device which is universally recognized to work with almost all new car brands.
The system is enabled with several electronic and gas sensors in the form of Oxygen, carbon dioxide and even other toxic sensors to be able to detect the levels of polluted emissions arising from the engine as a result of any fault. This is when it gives the Check engine light.
7/ How do I know the OBD system is working corectly?
The working of any OBD scan tool device depends on the state of the given car. When the tool is plugged in, as is the case with most of the plug and play devices, the mere tap of the scan button is enough to prompt the data code reading to proceed.
When you turn on the ignition, the “Service Engine Soon” or “Check Engine” light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected. If so, you’ll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the environment!
Some OBD scan tools with Bluetooth features however have remote diagnostic capacities. The timeliness of the data and the display of the data are some of the parameters to check if the OBD 2 is working correctly.
8/ What does it mean if the light turns on while I’m driving?
If the light comes on and stays on, the OBD system has detected a problem. Your vehicle might have a condition that wastes fuel, shortens engine life, or causes excessive air pollution. If left unaddressed, these conditions could also damage your vehicle and lead to increasingly expensive repairs. For example, OBD can identify a loose or missing gas cap (which wastes fuel and contributes to smog) or engine misfire (which can lead to severe or permanent engine damage).
9/ What should I do if the light stays on?
There is no cause for panic. The vehicle is just telling you to seek attention soon. When you reach your destination, make sure the gas cap is not loose or missing. Always turn off your engine when refueling. If the light does not go out after a few short trips following gas cap replacement or tightening, have your vehicle serviced by a qualified repair technician soon! Delaying assistance could lead to more expensive damage.
10/ What does it mean if the light is blinking?
If the light is blinking, a severe engine problem such as a catalyst-damaging misfire is occurring and should be addressed as soon as possible. You can still drive safely, but should minimize your time on the road. Try not to drive the vehicle at high speed or with excess weight (such as towing or carrying heavy equipment).
11/ What will my technician do when I take my vehicle into the shop?
Ask your repair shop if they employ trained OBD technicians. A modern repair shop or dealership should have an OBD scan tool (a small, hand-held scanning device) to diagnose the cause of your vehicle’s problem. These technicians will have the proper tools and will know best how to diagnose your vehicle.
The technician will connect the scan tool to your vehicle’s computer (usually through a connector under the dashboard) and download information that can pinpoint the problem. The technician can then repair the vehicle based on manufacturer recommendations. OBD actually helps repair technicians do their job more quickly and reliably, helping you avoid unnecessary repairs and trips back to the shop.
12/ Will the repair be covered by warranty?
Warranty coverage varies depending on components and individual manufacturer warranty provisions. In most cases, however, responding sooner rather than later is likely to minimize the individual owner’s repair liability. The CAA requires an 8-year or 80,000 mile warranty on the major emissions control components such as the catalytic converter, and a 2-year or 24,000 mile warranty on other emissions control components.
13/ Are repair costs going to increase?
Thus far, no increase has been seen. Real world experience from operating programs has shown that the average cost for an OBD-triggered repair is comparable to that associated with repairs triggered as a result of more traditional tailpipe testing of OBD-equipped vehicles. Regardless of the test used to identify a failure in the I/M lane, it is standard operating procedure for a repair technician to consult a vehicle’s OBD system before attempting a repair. In fact, the repair community has been using the kind of information provided by OBD systems to diagnose and repair vehicles for more than twenty years. The fact that these systems and the information they provide has been standardized since MY1996 makes using this information easier while leading to more accurate and quicker diagnoses and more cost-effective repairs than possible with earlier OBD systems.
14/ Can the OBD system be repaired, deactivated, or modified?
The rule of thumb when it comes to emissions-related vehicle repair is that any modification that changes the vehicle from a certified configuration to a non-certified configuration is considered tampering: this applies to both vehicle owners and repair facilities and is, therefore, a Federal offense. Replacing a catalyst with a straight pipe is one traditional example of tampering. Likewise, overriding the OBD system through the use of high-tech defeat devices or non-certified computer chips, for example, would also be considered tampering. The OBD system may, however, be repaired back to its original certified configuration with certified “performance chips” or appropriate aftermarket parts.
15/ What should I do if the light goes out before I take the vehicle to the shop?
Usually, nothing. If the problem that caused the light to come on is addressed, the OBD computer will turn the light off. This is not an indication of a faulty OBD system. In fact, the system is doing its job by verifying that a problem temporarily existed but has since been corrected; perhaps a loose gas cap was tightened or a fouled spark plug was cleared. Your vehicle needs no special attention unless the light comes on again.
16/ Why are states required to include OBD checks as part of their inspection and maintenance (I/M) program(s)?
This computer-based early warning system was required by the 1990 Clean Air Act (CAA) and comes standard on all MY1996 and newer light-duty cars and trucks. The CAA also required that checks of the OBD system be included in all mandatory I/M programs to help ensure that vehicle owners take this early warning seriously. Many states have already incorporated OBD checks into their I/M programs, and many more are on schedule to do so within the next few years.
Despite numerous improvements in automotive technology, motor vehicles continue to be a major source of air pollution, accounting for approximately 77 percent of the carbon monoxide (CO) and 45 percent of the ozone-causing nitrogen oxides (NOx) in our nation’s air. I/M programs help reduce excess emissions by identifying vehicles in need of repair and requiring that they be fixed. For MY1995 and older vehicles, the most effective way to identify needed repairs is by measuring tailpipe emissions. In some cases, however, a vehicle may need repair before emissions increase. For MY1996 and newer vehicles, the OBD system makes it possible to detect malfunctions before it leads to high emissions. The OBD computer monitors a wide range of emissions controls and lights the “Check Engine” light if a problem is detected.
17/ Why can a vehicle pass a tailpipe test but fail an OBD test?
OBD and tailpipe testing are two different approaches to identify vehicles in need of repair. The OBD system looks for broken or malfunctioning emissions control components, while tailpipe tests sample a vehicle’s exhaust to see if it is above or below certain prescribed limits. Given the robust nature of today’s emissions control components, it is entirely possible for an individual component to malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components (like the catalyst) can temporarily compensate for the part that is broken; however, these other components can only do double duty for so long before they, too, begin to malfunction. Because of its ability to monitor individual components, OBD is able to give motorists an “early warning” that repairs are needed; it is because of this “early warning” capability that OBD will sometimes fail vehicles that would otherwise pass a tailpipe test. In addition, OBD also monitors for leaks and other malfunctions in the fuel system—problems that traditional tailpipe tests were not designed to identify. Most state and local areas also include a gas cap pressure test as part of an emission inspection.
18/ What else can I do to make sure my vehicle is running well and to minimize its environmental impact?
Today’s vehicles are highly sophisticated and efficient. OBD helps to ensure these vehicles are running in top shape, but you still need to maintain your vehicle according to the manufacturer’s recommended schedule. Keep up with routine maintenance and keep an eye out for your Check Engine light. Always turn off the engine before refueling and always make sure the gas cap is securely tightened. You’ll save money on fuel and repairs while helping to do your part to protect the air you breathe. In addition, driving as little as possible by combining trips, carpooling, walking, biking, or using public transit are all things you can do to help minimize vehicle pollution.
19/ Troubleshooting Code Readers/Scanners?
However much the hype we may have with OBD scan tools, there are tools which are not likely to give you the desired results and may force the user to carry out corrective checks. The processes of trouble shooting the OBD scanner differ from one brand to the other.
The troubleshooting details are usually found on the user guide. However, if you are not in possession of this all important accessory, then driver has no option but to visit the manufacturer website, or if the device is a Bluetooth one, updating it may help the user to be able to know the procedure of getting the OBD scan tool working again.
20/ How do we measure OBD-II output?
The on board scan process is a simplified process done by the OBD devices which are usually installed at specific points on the vehicle. The old generation OBD scan tools were installed on the dashboard with a cable popping and connecting it to the engine.
In the modern ones, the area below the driver’s seat is where to look for.
The process of OBD II scanning may depend on what the car fault is. In some cases, the driver can prompt the tool to carry out a general scan while in most cases, the process with the check engine light function being the result if there is fault.
Depending on which trouble is detected, the MIL is likely to flicker continuously thereby giving the driver an indication of the seriousness of the matter. This does not however mean that the driver has to visit the mechanic immediately, though doing so would be the noblest thing to do.
21/ Resons which can make you purchase a car diagnostic scanner?
The need for dependable, result oriented engine information reporting made it imperative for all the new car models to be fitted with OBD scan tools. However, it may be imperative to buy one if your car is not fitted with one to comply with the legal; requirement in the United States that all cars be fitted with the device.
Having a car without the device is an offence which attracts heavy fines or jail terms.
In addition, the OBD scanners are good for the preservation of the environment, thus reduces the chances of some airborne conditions arising from engine fumes.
OBD scan tools may just be the all important link in reducing the overall motorist budget. The time taken at the mechanic shop and the eventual cost are cut almost to half, most of the tools are plug and play with orientation to the do it yourself (DIY) operations.
The issue of the driver’s safety may be the most fundamental reason why each motorist needs these devices.
