A lot of people have asked me this question – Which is the Best OBD2 Scanner with ABS and SRS out there in the market today? Well, there are so many scanners out there but they are all based on different technologies. So let’s get right into it and take a closer look at each scanner and compare them against each other.
The first type of scanner is the OBD2 scanner which uses an OBD interface to interface with your vehicle computer. The data collected by these OBD2 scanners are usually stored in a non-volatile memory and they can be accessed from any computer. OBD2 scanners can also work with a flash memory or SD card, but this type of scanner requires special installation to support SD cards. The advantage of this OBD scanner over others is that they do not need any external device to interface with the car’s system; however, they do require an OBD reader to read data from the drive and convert them to an electronic signal.
The second kind of scanner is the Real-Time Blocking Scanner which works by detecting any anomalies in the read-out from the monitor. It then triggers the corresponding actions such as switching off the lights and sometimes even switching on fans to cool down the OBD2 drive head. This scanner works great in cases where you need to take corrective action without waiting for a mechanic to change the problem. Although Real-Time Blocking Scanners can be used to manually detect problems with the OBD2 system, they are not recommended because of their slow scanning speed and limited data and function scope. They are best suited for cases where the only purpose of the scanner is to provide assistance to a technician who needs to perform a diagnostic test of the drive before advising the owner of the vehicle.
