Dr-1: Testing For Fault Codes
Using DRB-II, check for fault codes. Identify fault code and perform test as specified. See FAULT CODE DIRECTORY table. If DRB-II displays more than one code, repairs should be made starting with the lowest fault code. If a driveability problem exists but no codes are displayed, perform TEST DR-21 . If DRB-II displays a blank screen or NO RESPONSE, refer to TEST DRB-I at end of self-diagnostic tests.
