Know Everything About The OBD Car Scanner

What Is An OBD Car Scanner

OBD car scanners are devices that let you read and diagnose error codes your car displays. Without them, you won’t know what’s wrong with your car. In fact, mechanics, too, use these devices to diagnose car problems. There are two main types of OBD scanners on the market: OBD1 and OBD2 scanners.

On-board diagnostics (OBD) is an automotive term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD car scanner has varied widely since its introduction in the early 1980s versions of onboard vehicle computers. Early versions of the OBD car scanner would simply illuminate a malfunction indicator light or “idiot light” if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle.

How To Find Your OBD Port

The OBD-II diagnostic port, also known as a Data Link Connector (DLC), is generally located on the driver’s side of the car or truck under the dash. The location will vary between different manufacturers, models, and car or truck model production years. ​​

Types Of OBD Car Scanner

There are three types of OBD Car Scanner :

ALDL (OBD Car Scanner)

GM’s ALDL (Assembly Line Diagnostic Link) is sometimes referred to as a predecessor to, or a manufacturer’s proprietary version of, an OBD-I diagnostic. This interface was made in different varieties and changed with power train control modules (aka PCM, ECM, ECU). Different versions had slight differences in pin-outs and baud rates. Earlier versions used a 160 baud rate, while later versions went up to 8192 baud and used bi-directional communications to the PCM.


The regulatory intent of OBD-I was to encourage auto manufacturers to design reliable emission control systems that remain effective for the vehicle’s “useful life” The hope was that by forcing annual emissions testing for California and denying registration to vehicles that did not pass, drivers would tend to purchase vehicles that would more reliably pass the test. OBD-I was largely unsuccessful, as the means of reporting emissions-specific diagnostic information was not standardized. Technical difficulties with obtaining standardized and reliable emissions information from all vehicles led to an inability to implement the annual testing program effectively


OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. A pin in the connector provides power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately. However, some technicians might still connect the scan tool to an auxiliary power source to protect data in the unusual event that a vehicle experiences a loss of electrical power due to a malfunction. Finally, the OBD-II standard provides an extensible list of DTCs. As a result of this standardization, a single device can query the onboard computers in any vehicle. This OBD-II came in two models OBD-IIA and OBD-IIB. OBD-II standardization was prompted by emissions requirements, and though only emission-related codes and data are required to be transmitted through it.

Why We Need A OBD Car Scanner

OBD Car Scanner is a professional car diagnostics solution inside your phone, tablet, or laptop, running iOS (Apple iPhone and iPad) or Android.

Learn everything about your car!

Your car’s dashboard is probably home to a speedometer, a tachometer, a fuel gauge, and — if you’re lucky – a coolant temperature gauge. However, your car’s electronic brain (ECU) is actively monitoring dozens of parameters behind the scenes that you, the driver, could find useful. This is where diagnostics hardware and apps like Car Scanner ELM OBD2 step in, putting all of that data at your fingertips.

Find problems before they happen!

Watching real-time parameters, you can discover a problem even before it turns on MIL (“Check Engine” light).

“Check engine” / MIL is already on? 

We all, well at least, everyone who drives, have felt that second of irrational panic when the “Check engine” light on the dashboard suddenly lights up. It is, of course, recommended that you drop your car off at a service station as soon as possible, as in most cases you have no way to know where exactly the fault lies. Until now. With Car Scanner OBD2, checking fault codes is just one of the many things you can do.
