repair all other Diagnostic Trouble Codes (DTCs).

if no other Diagnostic Trouble Codes (DTCs) are retrieved, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test.

if the unlisted Diagnostic Trouble Codes (DTCs) return, VERIFY that the correct part number module is installed for the vehicle and if correct, install As-Built data from PTS following the diagnostic scan tool instructions under Module Programming > As-Built.
