Powertrain Verification Test VER-2
Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. Check if initial symptom still exists. If initial or another symptom exists, repair is not complete. Check for any technical service bulletins that may apply to symptom. Go to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom. If initial symptom no longer exists and no DTCs are present, test is complete.
