1. A portable code reader/scanner for interfacing with a vehicle'"'"'s computer via a vehicle data link connector comprising:
- a housing with a hollow interior and an exterior comprising a keypad and a display screen;
a connector on the exterior of the housing configured to connect to the vehicle'"'"'s data link connector;
a processor containing a database and a diagnostic system within the interior of the housing;
vehicle interface circuitry configured to communicate, via a diagnostic cable, with the vehicle'"'"'s computer;
a data trouble code (DTCs) reading programming within the processor which reads and retrieves diagnostic trouble codes (DTCs) from the vehicle;
a DTC database and analysis program within the processor which contains DTC codes and analysis for each type of vehicle;
a live data database within the processor which contains live data known ranges of normalcy (norms) for each type of vehicle;
test circuitry programmed to open a live data mode with the vehicle diagnostic system and retrieve live data; and
an automotive DTC live data diagnostics program which determines the live data associated with retrieved DTCs and retrieves only live data parameters (PIDs), and their related tests, that are associated with the retrieved DTCs.

Abstract
It is the object of this invention to provide a system and method in the form of a program called automotive DTC live data diagnostics for analyzing live data, in real time, wherein received and analyzed diagnostic trouble codes (DTCs) are programmed to open the live data mode, selecting only the live data related to the tests used to determine the DTCs and loads and displays all the PIDs, flagging the abnormal PIDs. The invention eliminates the necessity of manually scanning through possibly several hundred PIDs in order to determine the abnormal PIDS.
