Testing for Battery Drain on 2008 Acura RDX

Had this vehicle come in with battery dying every week or so and found it had a 230 mA drain, this vid shows how I go thru the flow of diagnosing. Also you get an idea how to remove the radio, the navigation display and controller, and access the interior fuse box.

Thanks for making a vid on this - really narrows down all the potential problems. I'm hoping it's the HFL on mine too - just disconnected it. Had my '08 RDX on a trickle charger most of last year, every night after work - sometimes at work! I have no meter to test it with, but I hope we all have figured it out. I went in thru the passenger kickpanel to unhook that green damned HFL connection.

so i have an rdx of the same year and I am also having battery drain. same as in the video when I pull fuse. I tested all the components down the line like you show. My drain goes through the q connector as well. I can't find any module that stops the drain. Any tips on where to check next or anything I may have done wrong?

Hi there, if you are pulling the same fuse as in this Vid, and no longer have a drain, have you tried disconnecting this controller next to the shifter yet? It is a known failure for this problem. If you are pulling a different fuse, which one is it? And how many amps or milliamps is the drain?

@@ripsgarage it is fuse 23 on my car as well, when i disconnected the handsfree link the multimeter did not change. the only time I saw the multimeter change was when I removed fuse fuse. I disconnected every other module on the diagram in your video and none made the multimeter go down.

@@stephenhodge3581 And while disconnecting the hand free, you have the doors closed? Or door switched disconnected/triggered?

@@ripsgarage i had the switch ungrounded like you show in your video
