I have searched and found that my HFL module has most likely gone bad as it is stuck "booting up". Recently when my car sits for a few days without being started I have to jump it off. I know that this is probably caused by the HFL. I have read that it doesnt shut off when its like this and draws a small amount of current that is draining my battery just enough after a few days.

my question is, can I just dis connect the HFL module without it messing up anything else like the display, remote entry , etc...???

where is the HFL located? I will try to disconnect it. these things are $$$$

 

It is in the overhead console by the map lights. Take the sunroof switch out with a feeler gauge, then pull the map light out with your fingers. The housing is held on with 4 8mm bolts.

 

^^ yeah i agree, i had the same problem and i disconnected mine and it solved my battery problem. went to the acurea dealer and the service representative told me to disconnect it

 

where is it located?

 

My just says "Booting Up" if I try to use it also. Damn HFL

Hope this helps

 

u can by a unit on ebay for like 200 bucks and fix your hfl

 

Does the diagram above work for the 07 type S as well? Cause my BT is acting up as well and my battery is starting to die. For the past 2 days my car has had some trouble starting up. It sounds like it's dying and then fires up. How do I save my battery?

 

yes it should
