The Actron CP9125 PocketScan is a budget OBDII unit that reads and clears engine codes on any 1996 and newer cars or trucks.
There is vehicle specific codes that manufactures have added such as Vag-Com for Volkswagen but the basic error protocols were agreed on long ago and all 1996-newer cars have built-in.
This means any budget scan tool like the Actron CP9125 will be able to read any basic codes on most any vehicle foreign or domestic.
I have used the Actron CP9125 for many years (see video below) and it gets the job done for basic problems.
Being cheap doesn’t make it good but does make it not only affordable but easy to take a chance on.
The ELM 327 does work when Paired to a smartphone and can read and clear codes.

The INNOVA 6100P is an advanced scan tool that can read standard OBD2 engine codes as well as ABS and SRS errors.
