  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If test is being performed after performing a NO TROUBLE CODE (NTC) test, go to next step. If test is being performed after performing an OBD-II TROUBLE CODE test, perform TEST VER-5A. If test is being performed after any other TROUBLE CODE test, go to step 3).
  2. Check if initial symptom still exists. If initial or another symptom exists, repair is not complete. Check for Technical Service Bulletins (TSBs) that apply to symptom and return to TEST NTC-1A: NO TROUBLE CODE TEST MENU, or appropriate TROUBLE SHOOTING - NO CODES article for diagnosis by symptom. If initial symptom no longer exists, test is complete. Go to step 8).
