Some of the national brand autostores will check some codes for free.
A code reader will only show codes, not live engine data.
A scanner will read codes and show live engine data. Some manufacturers do call a reader a code scanner.
Yes, I believe the dealership will charge for diagnostics/hooking up a scanner.
A high-end scanner that will show codes and live engine data can sell for several K.
If you just want a code reader, they cost less.
