Best OBD2 Scanner FAQs:

How Does OBD-II Work?

These handy devices link up the computer database within your vehicle to diagnose all systems. Every tool is unique, but each will provide the capability of detecting DTCs (diagnostic trouble codes).These identify and locate potential problem areas containing trouble codes.
Today’s vehicles are a lot smarter and have the capability to self-correct issues. However, some issues need our external assistance. If the check engine or malfunction light turns on, this means the PCM (power control module) can’t decode your error.

Is An OBD2 Scanner Worth It?

Yes, owning an OBD2 diagnostic scan tool will save you both time and money at the mechanic in the long run. Even the most simple OBD2 model will pinpoint exactly what’s wrong with your vehicle, and you can take on basic repairs yourself.
