Whether they are being used by a driving novice or by an expert mechanic, car diagnostic scanners are easy, useful tools for assessing what may be wrong with a vehicle when a problem arises. They can be plugged into information ports that are built into a vehicle in order to determine where a problem may originate. All information scanners are designed to access and decode the messages that are transmitted through the vehicle’s on-board diagnostic system. Every vehicle that has been manufactured since 1996 has computer chips installed in it that monitor each system. These computers can be accessed through information ports into which the scanner can be plugged. These ports are generally located near the steering wheel, but this can vary depending on the vehicle. Some scanners that are more complex are also able to detect problems in multiple vehicular systems, such as in the engine, in the brakes, and in the tires. They then often connect to a computer to provide specific information about where the trouble lies.
Car diagnostic scanners have a variety of advantages to offer to users. They can be used on the road and can allow the driver to determine whether they can continue driving or whether they need the car to be towed to an auto shop immediately. A variety of car diagnostic scanners can be purchased either from brick and mortar auto supply stores or from the comfort of the buyer’s own home through online retailers like eBay. This guide discusses the reasons why purchasing a car diagnostic scanner can be beneficial, it discusses how car diagnostic scanners work, it takes a look at the types of problems that car diagnostic scanners can detect, it examines the different types of car diagnostic scanners, and it provides information on where car diagnostic scanners can be purchased.
Reasons to Purchase a Car Diagnostic Scanner
Purchasing a car diagnostic scanner offers a variety of benefits for its user. First and foremost, it can determine whether a vehicle is safe to continue driving or whether it needs to immediately be taken to an automotive mechanic. This is especially useful because car diagnostic scanners are completely portable and can therefore be used on the road if trouble arises while the car is being driven. Additionally, car diagnostic scanners can potentially help to avoid exorbitant charges at an auto garage. Knowing what is wrong with a vehicle makes it easier for drivers to fix the problem independently if the driver is mechanically inclined. If not, it helps drivers to ensure that the auto mechanic is only charging for procedures that are absolutely necessary for repairing the vehicle. Furthermore, mechanics often charge a fee to run their diagnostic scanners on a vehicle, so owning one can help owners to avoid these costs as well. Finally, car diagnostic scanners are useful when purchasing a used vehicle. Running a scan on a used vehicle before buying it can help the buyer avoid ending up with a vehicle that had mechanical problems from the outset.
How Car Diagnostic Scanners Work
Car diagnostic scanners operate by being plugged into one of the vehicle’s data output ports. Every vehicle that was manufactured after 1996 includes a 16-pin connector into which a diagnostic scanner can be plugged. This is the same port that automotive mechanics plug their scanners into to detect what may be wrong with a vehicle. These ports are usually located somewhere near the steering wheel, so users can run a diagnostic scan directly from the comfort of their driver’s seat. Initially, the scanner will signify whether the vehicle is safe to continue driving, whether it poses potential problems for the driver, or whether needs to be towed to an automotive repair shop immediately. The scanner can then be plugged into a computer in order to view more specifics about the problems that exist in the vehicle. Some car diagnostic software programs also include information about how much the necessary repairs will cost at auto shops in the user’s local area.
On-Board Diagnostics
Every vehicle that was manufactured after 1996 has a built-in computer with a diagnostic system that can be accessed via the vehicle's data ports. Each of these vehicles has a variety of computer chips that manage the internal systems, such as the engine, the transmission, and the brakes. When something goes wrong with one of these systems, the appropriate warning light flashes on the dashboard, such as the Check Engine light. The Check Engine light can be triggered for a variety of reasons. It can appear due to something as simple as a loose gas cap, or it can appear due to something as major as failure of the engine’s catalytic converter. Depending on the problem, the on-board diagnostic system will log the corresponding diagnostic trouble code (DTC). These codes are read by the scanner and are then interpreted into understandable terms by the diagnostic software program.
What Problems Can Car Diagnostic Scanners Detect?
Car diagnostic scanners can detect a variety of internal problems, and each set of malfunctions is given its own DTC.
P0100 to P0199
The first set of codes deals with the engine’s intake, exhaust, and carburetor sensors. If a problem arises with the mass airflow sensor, the oxygen sensor, the oil temperature sensor, or the fuel pressure sensor, it will be labeled with one of these codes.
P0200 to P0299
The second set of codes signifies an issue with the engine’s combustion cylinders. This could be a malfunction of the fuel injector, the combustion cylinders, the injection pump, the turbocharger (if applicable), or the throttle position sensors.
P0300 to P0399
The third set of codes denotes a problem with the engine’s output and ignition systems. This could be an issue with the crankshaft, the camshaft, the ignition coils, or the timing chain.
P0400 to P0499
The fourth set of codes deal with exhaust and emissions control, including problems such as exhaust gases spilling from the engine, water vapor inside of the catalytic converter, overheating, excess pressure in the exhaust system, or failure of the evaporative emissions control system.
P0500 to P0599
The fifth set of codes signify problems with the electrical system, such as an issue with the fuse box, the electrical wiring, the idle control system, the power steering, or the cruise control.
Types of Car Diagnostic Scanners
The main difference between the different types of diagnostic scanners is the types of codes that they are able to read. This impacts which system the scanner is able to assess to diagnose problems. Some only interact with the basic on-board diagnostic (OBD) codes, while scanners that are more complex analyze other problems as well. These can address problems with systems such as the anti-lock brakes and the tire pressure monitoring. Oftentimes, scanners that are more expensive will be able to diagnose problems in a wider variety of systems.
Car diagnostic scanners can be purchased from retailers offering automotive parts, either in brick and mortar stores or at online retailers like eBay, and eBay’s online marketplace offers a wide variety of vehicle diagnostic scanners as well. eBay allows you to purchase car diagnostic scanners from the comfort of your home, and additionally, they provide a feedback and rating system that allows buyers to verify the quality of the product and the reliability of the seller.
Searching for Car Diagnostic Scanners on eBay
In order to find vehicle diagnostic scanners on eBay, it is important to know how complex the scanner that you are looking for may be. The more complex the scanner, the more systems that it will be able to analyze. After this has been decided, simply enter your search terms into the search bar that is provided on eBay’s homepage. You should be sure to use the most specific search terms possible in order to more quickly locate the most relevant results possible.
