OBD2 Trouble Codes or Diagnostic Trouble Codes are defined by SAE (Society of Automobile Engineers). SAE is the organization that specifies the OBD2 standards. These include the one that defines all the generic Diagnostic Trouble Codes (DTCs). Car manufacturers follow these definitions when they assign DTCs for detected errors.

New DTCs

J2012 is the document that defines the OBD2 Trouble Codes. The standard hasn’t been updated for a while but few months ago it got a new revision. The newest revision contained a bunch of new DTCs. These DTCs take new technology such as hybrid vehicles into better consideration, for example.

OBD Auto Doctor contains now all the possible generic OBD2 Trouble Codes that exists. We added total of 3899 new DTCs to the software.

The software contains total of 18193 Trouble Codes. The latest PC & Mac software as well as the Android and iOS apps have all these codes included.

The codes include:

• Powertrain: 6631 codes
• Network & Vehicle Integration: 1017 codes
• Chassis: 363 codes
• Body: 165 codes
• Rest of the codes are manufacturer specific trouble codes

Multiple Freeze Frames

The latest desktop software version added support for multiple Freeze Frames too. Typically, only one freeze frame is saved. But with newer cars, it’s possible to store multiple freeze frames; one for each trouble code. The software will now read all available frames.

This is a great addition if the vehicle has more than one issue present. You get details from each issue, not only the first one.
