Odyssey battery draining


Asked by Vkp23 Apr 29, 2015 at 04:48 PM about the 2007 Honda Odyssey Touring FWD with DVD and Navigation

Question type: Maintenance & Repair

My odyssey's battery keeps draining!  We just bought the van in November.  We thought
it might had a bad battery so we replaced it.  Worked fine until it sat for a couple days.
Battery is completely drained.  No interior lights were left on.  When the battery was
working the front interior lights are not working when the lights are set to turn on when
the doors are opened.  They won't cut on with that switch at all but the back lights do.  
They will cut on if you manually press them. The little orange light that lights up the
center console is not cutting on at all. We were thinking it might be a problem with those
lights. Anyway, it's not the alternater as its draining while it's parked and off as if
something on the inside was left on but we can't figure what. Any ideas how we can pin
point it?

I just read a post talking about the doors and the battery draining. We have been having trouble with the doors seeming to hang up when we try to open or close it. It would act as if something bumped it and would beep and open/close back. The safety feature and all...

In other words could the door be related and how and how would we fix it?

Check YouTube for checking parasitic battery drain

You appear to have a parasitic drain problem. I had this on a 2008 as well as a 2014 Honda Odyssey van. What the problem was is that a AC relay fuse had gone bad. When the fuse goes bad, it constantly tries to engage the air conditioning compressor even when the vehicle is turned off. As a result, it keeps trying to engage the compressor until the battery is totally drained. The AC relay, which is less than thirty bucks, should fix your problem. Swap it out with a new one, and see if that fixes your problem. If it does not, please take your van to a real mechanic to do an electrical system analysis.

When you needed to to replace the AC clutch relay cuz it was draining your battery dead was your air conditioning still working

Great answers, but my problem was not the ac relay, Left slider door was not working and the drain was from the micu module in the rt rear of the vehicle...pulled the top left right plug off that part and the .6 amp current drain went to 0...no battery problems since, Now to figure out what's going on with that door...

I'm having a similar issue with my 2018 Odyssey. It's just over a year old and kept in the garage, so the battery shouldn't need replacing yet. I brought it to the dealer for a sliding door latch recall. Since then, the battery has been dying every weekend. After it happened the first time, we've been hypervigilent checking the lights, etc. We haven't left anything on or open. So we think it's the doors. I'm at the dealer right now waiting to see what they say....

GuruCTQH4 I am having the same issue. Could you let me know what the dealer said and if the issue was fixed?

I have the same problem and have not found the solution. It is draining 0.2 amp and if I keep the car standing for 2-4 days - It dies. I took out fuses one by one and check if current dropped. I didn't find any fuse that significantly reduces the drain current. I need help which components/subsystems don't go through fuse system.

I’m having the same issue. We are on third battery and replacing every two years.

Same issues with battery drain. I have been experiencing noted issues with doors and over the summer my AC did stop working. We are on battery #3 and alternator #2 (about 9 months span) Going to attempt to follow some of the tips noted in here.

We are on our 3rd battery. Did a parasitic battery draw test and had .32 ma draw. Pulled Backup #7 fuse and reading decreased to .02 ma. Looking at the schematic it’s showing the rear sliding door mechanism might be the culprit. Might have an issue with the micro switch causing an audible door alarm while in drive. There no warning lights in the instrument panel indicating the rear sliding doors are open. I’ll post my finding once I find the root cause.

We are also having audible door alarm while in drive. Switching to manual door silences the alarm but the battery drain has been happening along with it since fall. Waiting to hear your finding Odydude. Thanks!

Any answer to audible door alarm while driving? I'm having repeated dead batteries in 2016 Odyssey and have had problems with door alarm for past year (usually when very hot outside).

i had this problem on my 2009 Honda Oddysey. i did all the checks, replaced the AC relay, took it to several shops and still had the problem. I notice that there are 10 relays with the same part number as the AC relay. There are 4 under the front driver side above the fuses, 3 on the front passabger side next to the fuses, and 3 under hood 1 being the AC relay. I went through 4 batters in a years time. I thought if the AC relay could cause this problem, then any one could be a problem seeing that they are the same relay. I replaced them all about 4 months ago and it fixed the problem. I do not care which one was bad, all I know is the problem is fixed.

I have a 2006 Honda Odyssey. I've had the issue with the door chime staying on unless the automatic door switch is turned off. The drivers side sliding door sometimes works (when the chime stays on while driving) and sometimes doesn't (the chime will stay off while driving). I also have a parasitic draw going on that drains my battery in a day or so. The battery is brand new. I took the van to the Honda dealership and they were unable to find the issue with the draw. They did say that it appears the sliding door rear latch was faulty and the control unit. I've replaced both and hasn't fixed the battery drain. I don't want to spend another $135 at Honda just for them to tell me they don't know anything. What would be the next step to find out what's killing my battery?

Do your sliding door closes and unlatches about 1/4”

GuruH1WTR< My right door does that and I have the parasitic power drain issue W/the door alarm while in gear.

For anyone who suffers from parasitic power drain issues and whose sliding door doesn’t latch properly, attached is a photo of the sliding door latch motor. Remove it from its housing and check for a seized spring latch. Spray it with WD40 and move it back and forth. Once it releases add some grease and replace and it should fix your problem.

I fixed my door, It was one of the micro switches on the rear latch, it was bent out of shape causing it to not engage Let's hope this fixes the parasitic drain issue as well, fingers crossed.

I have a parasitic drain problem on both my 2006 odyssey EX with power sliding doors (I replaced left sliding door rear lock) and now my 2007 odyssey LX with manual doors has a 3.9 amp parasitic draw. If i remove fuse 22 the drain stops the 70 amp side is the problem. It supposedly supplies the passenger fuse box, but I pulled out every fuse and both Omron relays above the fuse box and the 3.9 amp parasitic drain persists. Does anyone have a wiring diagram of the circuit the 70 amp part of fuse 22 120 A/ 70 A ?


I have Battery draining issue too. I have the radio on - on accessory mode, in 10 minutes the battery is totally dead. The alternator and battery were changed but resulted in same problem when radio on accessory mode. My thought is the battery could be undersized --- and lesson is run the car if the radio is on. I have other cars but do not have this electrical problem. Any suggestions?

Guys if the culprit in the rear sliding door for the culprit and chaining the motor is the answer do you know how much will it cost


For months I suffered with parasitic drainage on my 2006 Honda Odyssey. Checked every fuse you can think of. After some of my own labor and lots of research I fixed the problem and it never came back. The cost $0. It turned out to be the rear passenger sliding door latch. I have a picture on one of my previous post. There’s also a video explaining the whole procedure.

I have a 2007 ex, buzzer would go unless I turned it off. Left side sliding door motor bad, computer thinks the door is open (buzz), won't go to sleep, battery dies in 3 days. Replaced it, $500 parts and labor, no problem since.


We have changed the a/c relays and still have the battery drain. We turned the power doors off. And is still draining the battery. We had a new alternator and battery installed recently. Any other ideas on what to check?
