Diagnostic Codes

(or Read Codes and Clear Codes)

The diagnostic trouble code option(s) that appear on the Diagnostic Menu screen vary depending on the vehicle being tested. For some vehicles, the menu option is Diagnostic Codes; for other vehicles, there are two menu options: Read Codes and Clear Codes, as described below.

The Diagnostic Codes option appears on the Diag- nostic Menu screen for vehicles that allow reading of diagnostic trouble codes (DTCs) with a scan tool.

The Read Codes and Clear Codes options appear on the Diagnostic Menu screen (instead of the Diagnostic Codes option) for vehicles that require reading of DTCs by visually viewing them as “flash codes.” For this type of vehicle, you identify the vehicle’s “flash code” num- bers and manually enter the numbers into the NGIS tool to see their descriptions.

When you use the diagnostic trouble code options, a screen similar to the following screen appears. The screen displays diagnostic test code (DTC) numbers and descriptions.
