Code Readers Vs. Scan Tools Vs. ELM327

Another option that may be worth exploring is a type of “scan tool” that actually functions as an interface between 

your car’s on board computer and another device, like a smartphone, tablet, or laptop. These are typically referred 

to as ELM327 scan tools, but they can actually function as anything from a very basic code reader, to an advanced 

scan tool, to the core of a DIY infotainment system depending on the software you use.
