1. retrace your work. i'm not exactly quite clear as to the Headlamp work you did. did you just replace the bulb? did you disconnect the neg. battery cable? any other wirings you've disconnected.

2. check fuses and fuseable links. from ignition switch to BCM (2) and 1 fuseable link. take voltage reading on ECM terminal 50 for Data Link Connector. this is Priority 1 so you can retrieve stored trouble codes. refer to Engine Control manual under Trouble Diagnosis for reference. hope this helps. manuals are in Knowledgebase section.

3. the video is good reference but may not be applicable on your vehicle. i agree Pin 16 is 12v power socket. that may be where the similarities end depending on the OBDll protocol used by Audi tho most Europians car makers also uses the ISO protocol as Nissan do. your 3rd gen Altima uses ISO9141. hope this helps.
