All and any help is appreciated the problem is that i bought a new yellow top battery about maybe 4 months ago and i bought a dd and my 07 tis has been in the garage for about a week and when i went to unlock the doors nothing happens so jumped my car and it was ok and then the next day the battery was good in the morning but i didnt start the car just unlocked the car to see and then around this time i was about to take the car out the battery is dead again. Do you guys think its a bad battery or is it something with the car that eats the battery while standing....also now im going to start driving my car 2 days a week so is there anything i should do cuz i used to drive everyday like take off the terminals or something...thanks

 

1) check battery.
2) if battery deemed good, you have a parasitic draw most likely from the HFL.

 

^^^+1

 

Yea my hfl keeps on saying booting would that be the problem, what would a fix be?

 

new HFL or disconnect the HFL and see if the battery continues to misbehave. if it says booting...your HFL is broken. do you use it?

 

no i never use it......and by disconnecting you mean completely taking it out will that mess with anything else like the navi command or voices?and do you know the part number or where can i get a new one? thanks for the help

 

i don't know if it messes with the other features. the new module is expensive. check the online OEM dealer parts stores for pricing.

 

You will lose navigation voice commands if you unplug the HFL...

Oh ok well im going to just take it out for a while and get a new one in a month or 2...so do i just take it out and leave it out and put everything back together?would that be ok? Also when I get the new one jus install it? Or would I need to reset it or something of the sort....and that one in the link is for the 07 tl? And im hoping they made the new better?

 

you can just disconnect it from the plug. i'm pretty sure it's plug and play but don't quote me on that.

 

Well I disconnected my battery since yday am going to hook it up if the battry dead if not im ripping that module out

 

Disconnect the HFL system (yes you can just unplug it), that was the cause of my battery drain issue, since it has been disconnected i haven't had a issue

 

thanks guys im taking it out tom....ill tell if that fixes it...crossing my fingers its just that

 

Please let us know how this works out...

 

ok im about to take it out now but how would i go about taking it out?is it the same way as the 04 to 08?and wht tools would i need to pry off the cover before i get to the module...

I think my written description in the "Bluetooth fails..." thread at post 221 is better, though. You can look at: https://acurazine.com/forums/showpos...&postcount=221.
