Considerations When Buying an On-Board Diagnostic Level Two (OBDII) Scanner
Just about every vehicle, foreign or domestic, made after 1996 has an OBD generation 2 connector for mechanics and automotive service personnel to quickly diagnose problems as well as monitor real-time information about the performance of a vehicle. Buying your own OBDII scanner means that any vehicle owner no longer has to go to a repair shop or garage in order to learn more about their car’s status as well as clear and repair problems indicated by warning lights.
When buying an OBDII scanner, the first choice you’ll have to make is between a stand-alone handheld unit or one that synchs up with a PC and/or mobile device in order to download and save information. Some units rely on cable connections to a PC while others use either WiFi or Bluetooth to wirelessly transmit information to either only Android or both Android and Apple mobile devices. Another consideration is whether you the software and/or app that interprets the scanner’s information is free or not, with some manufacturers offering software/apps/updates that only remain free for a limited amount of time.
Be aware that some scanners offer an incredibly amount of diagnostic information which may be more than some vehicle owners need or can profitably use. Some scanners graph and save information for offline use while others use onboard databases to more quickly arrive at fixes for thousands of problems. Most scanner tools allow vehicle owners to clear problem lights like “check engine” but if the problem is not addressed, the warning light will illuminate once again.
With such a wide range of options and styles to choose from, there is an OBDII scanner tool for every budget and vehicle diagnosis/repair need.
