SAN DIEGO - The Automotive Training Group (ATG) has released a full set of OBDII Trouble Code Quick-Reference guides for identifying a fault, determining what conditions were present when the trouble code set, identifying possible causes, and determining how to drive the vehicle to validate the repair. 

ATG's Technician Reference series includes a total of 12 handbooks, covering Buick, Cadillac/Oldsmobile, Chevrolet, Chrysler, Ford, General Motors, Pontiac, Acura/Honda, Toyota/Lexus, Infiniti/Nissan, Hyundai/Kia. The Trouble Code pre-conditions included with each trouble code in the handbook help properly diagnosis and repair trouble codes on late-model vehicles.

The handbook also contains an overview of OBDII theory, including OBDII Monitor explanations and Drive Cycle graphics. This information is critical for the running of monitors to verify a repair, which prevents embarrassing comebacks.  The handbook also contains Mode $06 information, concentrating on the newer CAN Mode $06.
