This is one of those videos that can genuinely save people an awful lot of grief and hassle. I just bought a Civic Mk8 1.8 EX to use as a runabout (to save my Lexus GSF from parking dings, etc). It was very satisfying getting such a good car, loaded with kit (too good in fact for a runabout to use and abuse), for very little money, but within the first week after standing idle for 3 days I found the battery completely dead. I thought to myself, 'what on earth have I done - giving myself a load of hassle when I have a reliable car.'I knew that Hondas suffered from battery drain, so googled it and came across your video. Armed with multimeter, I followed your process and sure enough removing the HFT eliminates the excess drain. A mate of mine dismantles civics and has an identical module, so I now have the dilemma of whether to fit it so I have hands free, or leave it to avoid future problems (what would you recommend?). Either way, a top notch video that helped me quickly find/eliminate the problem which otherwise would have been a nightmare to find and have me regretting my decision to buy a second car. Well happy - thanks for sharing.

This is very similar to the issues we had. When you do the tests on measuring the current please do it with the car locked and alarm system on. Our issue was the Bluetooth module draining the battery.

Great vid. Been having problems with this for years 2006 Civic CDTi 2.2 - drain at approx 0.3 amps, which then settles at approx 0.18. In the past i've pulled every fuse and no change. Just experimented today and found that locking the car does the trick. Drops down to approx 0.03 amps. Unlock and it goes back up. Appreciate there are many reasons for parasitic draws and the certainly the blue tooth module is one of them - but I dont even have one.

It took a lot of work to find the problem. I am going through the same process. Hopefully your video will make it easy. Thanks!

Many thanks this help my civic battery drain , I was going to buy a new battery but you’ve save me from buying one . Once again thank you 😊

Appreciate this video man , this ended all my battery nightmares 😂

Man, I just want to say thank you, thank you, thank you. Using methodical approach I able to track down battery draining issue on my Honda Accord and guess what, it was the Bluetooth module.

Nice find, and good practise to always completely close all the doors to best simulate the conditions in which the battery drains.

Thanks had the same issue on my mother civic (2006). Was looking at getting the alternator changed , but thought i would try and confirm the drain, and then came across your video.

!! Here is how to remove the plastic panel !! I had the same switch between 0,22 and 0,54 a when car Was locked. My Bluetooth Box was Hot too. So i think i fixed it now with this Video. Thx for your help. :) Kinda sad tho u cutted out the most important part. (remove the plastic) Ok here is how i opened it (maybe it helps Anyone): (attention: left side wheel car) 1) clip off right side (i just pulled it) 2) remove small plastic over the wheel 3) push the clips there to lose upper part 4) open the door and clip off the triangle looking plastic on the very left side facing the door 5) unscrew the 1 screw here 6) clip off this part now You're welcome. =)

Thank you very much sir, I followed your method and found out that I had the exact same problem! By disconnecting the Bluetooth module the battery drainage stopped.

Thank you!!! My 2010 Accord is having the same issue, I have pulled all the fuses off from both the driver side and the passenger side fuse boxes and the current won't go away. Honda is crazy not putting a fuse before this. I have to keep a supercharger jumper in my car and jump it almost every morning. I will try discconecting this and see if it fixes the issue.

Very well done again sir. Thanks for sharing. In the US they also have many problems with the homelink unit. Fancy name for a Garage door opener module

Thanks for the video sir, been having this same problem with my 2007 civic 2.2cdti. I will certainly be checking this out and will let you know if it works. Thanks once again.

My same model of civic is going to a garage this week to get the same things checked. I hope they do as good a job as you.

Yeah I can remember handling a parasitic load like this but this time around it was the relay that another technician connected wrongly that was draining the battery. Good job 👌🏾

Thank you so much! I fixed the same problem in my civic by removing that same module!

Thank you for this, my civic had the same problem, saved me some money although I had already bought a battery thinking it was that.👍

Good job. Saved me loads of time, glad I found your video before I started. 👍

Brilliant video, solved my problem with my civic mk 8, thank you

It's not boring ... I'm learning things ... even though you guys drive on the wrong side of the road :-) and your steering wheel is on the wrong side of the car ... but that's okay, still learning anyway.

Great video... I've been having the same issue with the battery draining on my '06 Civic. Gonna try and diagnose the problem with a multimeter and see if its the same module causing the issue.

Great job and channel. Please continue, we always have some ideas to solve our problems when we watch nice worship repairs tips. Thanks.

Thanks I had the same problem ,same car (other makes have this problem too),As I dont want to use the phone whilst driving I just took the module out ,that was 2 years ago,car running perfectly no more flat battery.And replacement module is expensive anyway.

God bless you. I'm subscribing from this video alone.

LONG video, could do with some editing buddy. But thank you for the video, this was exactly the problem on my 2006 civic!! 🙌

Any reason why you do not use a clamp on current probe when checking problems like this? Not only are there handheld types that can measure DC current, but also ones that can connect to an oscilloscope. It would save time having to break open the circult to insert a meter. Also thanks for posting these videos. I have learned a lot from them.

cheers different problem but helped me fix light problem on a civic

Hi, thanks so much for your detailed analysis on this. Guess what? My Honda Civic Mk 8's Bluetooth gave up end of 2019. I found it unreliable and often failed to work at all when pushing the steering wheel buttons to use. No problems noted, however, during early weeks of UK lockdown with the battery (but I was driving often) then a few months later (less driving working from home) I had to charge the battery a lot! Anyway, enough was enough so I called the AA to check the battery which was the top of the range and only 2 years old and they found the 0.5-1amp discharge going on. Advice was ask my mechanic. Anyway, found your video at the top in KZfaq, tried it out as you suggested, got my multi-meter to verify and spot on! The Bluetooth module was warm (like you said) also. Can you believe it? Anyway, well pleased with the result thanks to you my friend. Wondering if it's safe to buy a pre-owned Bluetooth module to replace the faulty one? Any recommendations? Am guessing won't have much life in them since they're all at least 9-14 years old right? For the mk 8? Thanks again - God bless.

This something helpful! I just now having same problem with my Honda Civic 2009 model, so I'm definitely going to try it out and see how it helps my car from no power at all after not using it about one week. Thanks for this tip!

Thank you so much i really like this car, now l might even like more l am going to check this out this was a great a presentation very well done.

I like this method of a parasitic draw test. I'm guessing using the inline fuse tester like that protects the internal multimeter fuse too

The bluetooth module looks good, pretty sure the corresponding push buttons on the steering wheels are damaged causing the module to stay on.

Did you ever solve why the Bluetooth module was causing the issue? Did you repair the module itself or did you just buy another one?

Another excellent video. Stumbled across your channel recently, I'm now subscribed and an avoid follower. Keep up the good work..

civics before 2000 were the best.

Thank you very much! Had exactly the same problem! All the best🍻

Excellent video, watched every bit. Would a thermal camera have helped? I've seen a cat phone come with a thermal camera built in. Just wondering . Thanks for your effort.

Love this guys videos! Always helpful gald you got ads running!

Nice video with good explanation. I have a Honda civic 2007 that has the exact same problem of draining battery. This has been informative and useful to me, thanks for sharing.

Following your video, I have notice that the interior light is drawing 3.5A. The interior lights includes: the spot lights, the ceiling light, the ignition key light, and the trunk light. Removing that fuse cause my car to not start. So far, I have managed to locate the trunk light connector, and disconnect it. It didn't change anything. Where can I find the other connectors?

Hello. I have the same problem with my 2007 Civic. Is it possible to drive without the BT unit or generate it more problems? Thanks a lot!

Oh, uni-t do a great clamp meter, the ut210e - well worth it. Expect you've bought one since you posted this vid in 2016 :)

Hi. Great video! At 23.52 you mention about it not dropping below 0.13 & that something else must be causing a drain too. Mine is reading 0.13, I was curious to know what it was causing it for you?

Great video buddy.

Hoping this is my problem. Been driving me mad. Have had to have key recoded now as car wouldn't start and alarm wouldn't stop, so immobilised. Costing me a fortune. New battery néw alternator just to find out its a drain. Now weak alarm battery after all the flat battery problems. . Any idea how long I will need to run the car to charge the alarm battery ? Scared to turn the car off now.. I'm case I have same issue.

Hi Good video..nice and clear. I just tested and failed my Bluetooth module on civic 2007..can I just unplug the unit and leave it or will that leave eml lights and codes?

Thank you you have really helped me I have liked and subscribed all the best

Got an 07 civic hybrid, put 11 batterys in it in 1 year

Great video. I have the same car and have a fault with the alternator not charging, it's been tested off the car and works, battery is brand new also. The fault that keeps coming back is power supply, IG1 power supply unit. Abs eps every light comes on due to battery being dead and not charging. Any ideas appreciated. I've given up

Boot (UK English) Trunk (US English) :-)

Thanks you for this valuable information.

Where did you but the fuse load adaptor? I tried 3 different auto part stores

May I ask you?I have a probleme a litlle bit different probleme.When I lock my car doors with a key controler and do double click.In 10 min.hazard ligths comes on and drains my battery. Can you give me any advice. Many thanks

i put the trim away but dont know where to find the module

Great detailed video. Cheers

Where you based? How much did you charge for this? I have same car with similar problem..

Thank you man!

My 06 civic lx doesn't have Bluetooth and still has this problem. Perplexing problem that old Hondas have.

hi LM,i havr a question.what is the connection between regular 12v battery and hybrid batteries of HCH car.

Very well done

Thanks! Nice! Done!

I can’t find the module… I have a 2006 Honda Civic EX, and it’s not by the fuses on the driver side, nor is it behind the glove box, any help please??

What is "normal"? How much SHOULD the car draw off the battery when parked?

I think I have a similar problem with my civic. Its now sunday and I the first time it happened was wednesday the breakdown guy came and jump started it which worked but told me something like the fan was draining the battery and to get it looked at asap! Thing is my garage is busy til Wednesday of this week and the car started fine thursday, friday and saturday but went to start it today and it was just flickering but dashboard lights came on! So annoying as I need to get to an interview. Hopefully I can get the garage to look at it and fix it! I've also been trying to find a mobile mechanic to look at it but they seem busy too! Do you know if this is an expensive repair?

Hey thanks for the tutorial!! I'm just wondering how did you remove the bottom panel to get got the Bluetooth?

Hi, can i check the battery draining fuse or problem without the equipment you used? If not whats the equipment you used?

great thanks, but i have a question. what about radio code, i know when you disconnect the battery you need anti theft radio code later ?

Windscreen (UK English) Windshield (US English) :-)

i have the same civic ex, i removed the HFT bluetooth long time ago (it was draining 0.21) and i still have a 0.29 drain , coming from same F16 fuse , how can i find who's draining that 0.29?

I have the same problem, does anyone know where I can get a new module? Either Honda or a brand that will work in a Civic 2016?

I have a similar problem with my 2006 honda civic 2.2 cdti mk8 but mine is the se spec it doesn't have sat nav or Bluetooth module any help would be much appreciated?

Hi. Could you please answer me a question. My car is 2017 Honda CR-V. After I parked it overnight, its battery died. I followed your instruction to check, and connected the meter with the negative point of the battery, but the meter just shew zero. So I don't know why. Thanks for your reply.

My car has parasitic current draw of .02 amps under 12.6 volt 45ah battery. What would be the voltage of the car after sitting straight unused for 48 hour????

HI can you please tell me what you did to get it from 0.13 to 0.01 ? I had the same problem was 0.47 with bluetooth plugged in after taking it out it drops to 0.13 like yours did.. what was the other issue ? Thanks Scott

Thank you

How do you connect your multi meter leads up to test? It looks like you connect both leads to negative terminal? This correct?

Me after watching this video: teleport in the car and unplug the Bluetooth module ○.●

Hi can u tell me if this is a common fault my civic is type s with same prob year is 07

I have the exact same 2006 executive Honda Civic and exact same is happening to my battery. Does anyone know what is advised after I take the Bluetooth out. Is the wire safe or does something need done to the wiring or is it with just buying a exact same Bluetooth and fitting the new one thanks

can you still drive car with the module out?

Do you have to use the fuse load adaptor? Or can you just use the volt meter connections? I tried the connections and the readinds didnt seem correct, It showed like 10.65.. My battery drains from 12.5 to 10.00 in 30 hours

excellent video companion the box is the hands-free? Traductor google jsaja gracias

where was that box located? i have an 06 si and mine has a dvd player installed on it and my battery drains, ive unplugged the fuse and still drains also tried unplugging the dvd itself still drains, then located the back up fuse #23 under the dash and it still has power when i unplug the positive terminal. what do you think it could be?

1 drain here was from HFT control unit, wich i d/c , the other components aren't so easy to check... so i'm stuck with a 0.25A drain .... F16 = MICU, Immobilizer-keyless control unit, Gauge control module (tach), Gauge control module (speedo), Hands-Free Telephone control unit

Easy, the problem is the steering wheel is on the wrong side m8.

Very helpful can you buy a replacement for the bluetooth? Thanks

HI, I have a Honda Civic 2009 1.8 I-vtec and i have a similar issue, My battery light is constantly coming on as i drive, I've recently removed and "serviced'' the alternator, bought a brand new battery, performed a charge test and all was fine, however 20km into my drive to work my battery light came on. As a quick fix, as I've watched your video, could i lust remove the fuse from the exterior fuse box that caused the "your issue"? Also my car does not have bluetooth/hands free kit fitted in.

Soy de Uruguay ...vivo en espain

Hard to find... i was sure the fault was from a frequency module just like the smartphone issue . jumping the amperage going straight to frequency...this it is always in physics and electronic. in this way iphone use sofware upgrade to kill their battery , was proven .

Hi lmautos where are you based. Or could I ask advice

Hi I have the same problem with my Honda civic 2007 diesel ctdi but it takes about 1 minute to go into sleep mode and some time it does not go into sleep mode.I notice I have a parasitic draw of .6amp when this fault occurs . any ideas !

Good job but it's the module of what

I'm having the same problem...honda won't tell you how much they cost new!

In my case, I suspect the idiots that changed the radiator pinched a wiring harness.
