Any ideas battery keeps draining. I disconnected the home link and that worked for a week but now it's dead again. It's a new battery.

 

Failing HandsFreeLink (HFL) module?

 

Home link or Acura Link?

 

How new is new?

 

2 weeks.Had the battery and alternator checked ok. Disconnected the HFL and still having problems. Any ideas?

 

I disconnected the hands free link HFL. Any ideas?

 

I disconnected that and it worked for a week. Now its dead again. Any ideas?

 

My advice is start a parasitic draw test.

 

 

+1, easy to do, just need multimeter. Search YouTube for a video on how to. Helps to have two people, makes it go faster.

 

Not sure what year you have, but I belive there is a known issue with the Acura Link module. If I am remembering correctly, it is part or the module with XM in the driver's quarter panel of the trunk.

There was a whole lot of talk about it here between 2005-2007 when the TSB was released. Pretty sure it affected the MDX too.

 

Thanks for the advice. Took it to my buddies shop and disconnected the harness where the map light is and its good now. Amazing what a problem this is with these cars

 

Thats a good buddy to have...
