DTCSearch.com is a free service, which has the most up-to-date database of diagnostic trouble codes (DTCs), and allows you to search for generic and manufacturer-specific codes.

While obd-codes.com is the undisputed leader in this field, DTCSearch.com has a much simpler and more intuitive interface. Best of all, every DTC page has a link to the corresponding page on obd-codes.com!

Give it a try, and bookmark the page -- it may come in handy one day!
