That service bulletin only applies to a 2005 with the VIN numbers of 19UUA6...5A000001 through 19UUA6...5A030286. Its not for my car, which is a 2005 and it surely does not apply to a 2007. Sorry!

by the way, I popped the #7 fuse once and 1 other one while I was changing a bulb without the lights off.. And it popped something.. And I never have figured out what it popped. I disconnected everything and couldnt seem to isolate the issue. I assumed the MICU could be at fault.. but I never did pursue it because I made a work around for re-lighting the bulbs on my navi. But I never did figure out the issue. I never have checked to see if I have a parasitic draw but then again I have not had a problem starting my car. So, I would be curious if a MICU would fix yours. But at the moment I cant find a MICU on acura diagrams

Was this ever resolved? I have a 2007 TL (no NAV) and am on my 4th battery. My mechanic claims that there is a short somewhere, but that the draw on the battery stops when fuse #7 is pulled out. Thanks.

 

Did you read through the thread

 

I did read through the post. Is the MICU the solution? I've seen other posts that state that the Hands Free unit is the problem. Other posts noted that it could be the locking mechanism.

 

Do you have an HFL unit attached still? That's one of the biggest offenders. I'd start there, then the lock. then the MICU.

 

OK. Will do. Thanks.

 

Same symptoms here....if the car sits for a whole weekend, the battery will be dead, and I haven't noticed the nav display unit remaining on afterwards. If you end up getting yours done be sure to update whether or not it's fixed!

Yeah I disconnected the HFL and I was using a meter to test for phantom leaks, and I noticed a fuse was drawing a significant amount of current every 30 seconds or so. I can't remember exactly which fuse it was of the top of my head (I did it about a month ago)....but after finding this thread, I would bet on it being the same #7.

Ultimately my solution was to just not let the car sit for over 3 days and I would be fine....not exactly the optimal solution, but I'm going to have another look at it this week. I don't think it's my navi unit staying on but I'll update accordingly.

 

is the #7 fuse under dash or under hood? It could be a bad relay switch. Try to find the parasitic draw by pulling the relay out until you find the bad relay. I think the culprit relay is MG clutch relay (under hood), so check that one first.

 

I dont know if anyone has figured out their problem but I had about a 600 milliamp drain coming from interior fuses 6 and 7. Whatever it was was causing the HFL unit to stay on. I finally unplugged the master power window switch in the drivers door and it dropped to 20 milliamps and the HFL unit shut down. Oddly enough I plugged the master power window switch back in and after starting the car and shutting it off the drain is gone. Dont know how or why and dont really care as I've been dealing with dead batteries for almost 3 years. So to anyone having this problem you may want to try that and see if it helps. Just thought that I would share my experience hoping it would help others.
