could someone explain the basics to a noob?
thanks in advance
OBD-2 is the standard by which diagnostic codes are recognized and sent to the PCM for storage and availble at the connector under your driver's side dash. There are standard Diagnostic Trouble Codes (DTC's) used by the automakers. Then each mfgr can set a group of its own set of DTC's.
CAN bus is the computer "wireway" that sends the signals, like a network cable for your PC.
Here's a place to start reading:
