In addition, the OBD2 scanner can retrieve freeze frame data, including essential engine parameters like RPM, fuel pressure, fuel trim, engine coolant temperature, etc.

This OBD2 scanner can get the I/M Readiness status, which checks the monitors on your vehicle, such as the misfire monitor, fuel system monitor, comprehensive components monitor, catalyst monitor, O2 sensors, EVAP, and so on, to ensure that your vehicle is ready to pass the annual smog inspection. Because of this, you won't have to worry about wasting time or money on a failed smoke check.

It is a pity this product sometimes gets trouble connecting Wifi, but this scanner generally works well.

This scanner can help you easily read and erase DTC (engine failure codes) because it also functions as a battery tester and professional vehicle diagnostic equipment. You can accurately identify the source of your CHECK ENGINE light by using a look-up library that has more than 8,000 built-in generic code definitions.

This product may send commands to your car to test operations, such as turning the fuel pump on or off, turning the air conditioning clutch on or off, or retracting the electronic parking brake. The Auto Re-Link feature assists the driver in determining while driving if the problems that caused the DTC codes have been resolved successfully. The only downside of this camera is that it is a bit hard to connect to Bluetooth.

What to Look For in a best gm obd2 scanner?

The best gm obd2 scanner is the standard appliance in your life. Seeing that the item is introduced with many models with distinct functions and features, several challenges in selecting. However, anything has its solution, not except for that. We, the high-qualified expert in this area, will be available here to give you support.

Of course, looking for the best gm obd2 scanner which suits you most requires many criteria to consider. You are projected to think carefully about each of the features below so that your choice will be appropriate:


An OBD-II scanner's most important capability is not the actual scanning process but rather the data transmission abilities. Because the scanner itself doesn't monitor the vehicle, this phrase is somewhat misleading. Instead, the scanner communicates with the onboard computer through various sensors to assess problems. This, however, doesn't mean that the data the scanner receives is the same from vehicle to vehicle. Some scanners can read only basic trouble codes, whereas others can gather a wider array of information.

Code Reading

To get the check engine light code on an OBD2 scanner, the primary purpose is to provide you with the numbers. You can find the engine light code on a simple scanner, but some of them may also provide you with additional information about what the code means. If you have a small screen and can’t read the definitions clearly on your scanner, you might want to get a model with a larger screen.


The majority of OBD-II scanners can be connected directly to an OBD-II port on the car with a cable. These scanners do not require batteries to function. They draw power directly from your battery. Wireless scanners with separate display units/app and a plug allow for easy mobility.

Live Data Scanning

With the advancement of onboard computers, modern vehicles can now monitor a large number of their subsystems simultaneously. You can check on the performance of your vehicle using live scanning. The technology has significantly advanced since 1996, so you can monitor your vehicle's operations in real time. You can, for instance, find out why your vehicle is losing gas mileage.


All of the car manufacturers have their own unique codes. Because the OBD2 system is standardized, the codes are not. To select the best scan tool, you must know whether your vehicle is included. These devices will have most of the major domestic businesses, including Toyota, Ford, and Honda. If you have a foreign or special vehicle, you must look for a scanner that is compatible with it.

Types Of OBD2 Scanners

A OBD-II scanner plugged into the OBD port is a quick and simple engine monitoring setup. However, it doesn't enable you to move around the vehicle while working on the engine bay. Battery-powered machines are also non-operational. The advantage of wired scanners is that they offer a link to a computer to translate codes. Because vehicles can be driven without wire, this option is more popular. Wireless scanner linkages are more difficult to establish at first, but the mobility advantage makes it hard to resist when working on an engine.

Information Processing

Commonly, an OBD-II scanner provides plain English with a nice resolution, rather than the underlying trouble codes. Even high-grade scanners that provide almost exactly the same data as those at the low end are rare. Whenever you look up the code or use a scanner that translates it, you will comprehend the code. Higher-end scanners that offer repair solutions are the best investment.
