Battery DEAD in 8 HOURS? (Shop Already "Fixed It"...? Acura MDX)
HTML-код
- Опубликовано: 5 фев 2024
- Sounds like this 2006 Acura MDX has a MASSIVE parasitic battery drain...
Customer says that the battery dies in 8 HOURS, and he needs to jump start the car every day!
He already had another shop unplug the common "HandsFree Link Bluetooth Module" based on my previous video, but apparently that didn't help.
He mentioned that the battery itself was tested at Advance Auto Parts, and that it checked out OK.
Let's see if we can reproduce the customer complaint, and pinpoint the actual source of the draw.
The results may surprise you :)

You know, Ivan, one of the biggest issues plaguing independent garages today is the lack of value some shop owners place on service information (SI). It's truly baffling how they manage to run their businesses without utilizing the tools available in today's modern age. I even offered my customers free General Motors virtual training classes, but believe it or not, not a single one took me up on the offer. The excuses they gave me could fill a book! What's truly concerning is that these are the same people working on your cars every single day.
Shops don’t seem to value training and knowledge yet this is needed to work on vehicles.
i want to now more
Left my W2 and never looking back. They’ve lost countless valuable employees and only approved training for unrelated areas requested by new employees who do their best to have someone else do their work.
The desire and will to learn is low among mechanics. I’m going to be teaching automotive part time at a local college in my area soon and I hope to be a part of changing that attitude over time. I think the trick is to give new techs real deal, practical tools and systems knowledge that can rapidly help them feel confident when hovering over an engine bay, or when they put a scanner in their hands. Right now, all too often, the education system is failing aspiring techs by filling them up with useless information for their day to day grind. Honestly, you can get a better education on RUclips through guys like Ivan, scanner Danner, Eric O, Bernie thompson, etc.!
Back in the early '90s when I worked for Snap-on Tools Corporation, every April, BOCES held their state finals at the New York International Auto Show. Young technicians from every state in the country would compete for the top prize. For many of these kids, it was their first time in New York. And every year, they asked me to participate as a judge in their state finals. We set up secondary ignition patterns on the Snap-on MT3000, requiring them to fill out a form indicating which cylinder was misfiring. I can tell you, those young people and their teachers worked incredibly hard to participate in the state finals. I hope you find as much enjoyment in working with the young students as I did.@@jeremyah78
Good to see that the franchises are still at the top of their game.
I have a cheap electronic battery tester. I think it works very well. But like all things it’s only reliable if you fully charged the battery and then you have waited 3 1/2 hours to test the battery. It gives the usual information like the CCA and indicates good, fair or bad. But what’s really important is the impedance of the battery. A good battery will have low impedance. Like no more than 5 ohm, older batteries in fair shape might read 7 ohm and higher than that your battery has become sulfated and either needs desulfated or replaced. I like the electronic tester for that reason but if I have reason to doubt what it’s telling me I pull the battery out of the vehicle and check it with my 1000 amp carbon pile tester. While it’s on the bench I check the specific gravity of the cells. I remove my batteries twice a year and charge them with a PulseTech charger that desulfates them. I’ve even recovered batteries that should have been replaced but are now the same as a new battery. The price of batteries has risen to the point that it pays off to maintain my own. I don’t know about doing the service for customers. It takes about three days on the charger. Balancing the cells probably isn’t an average DIY thing either. Typically only one or two cells will be sulfated the worse and the specific gravity will be low. Everything that was in the battery is still there and desulfating first and only adding distilled water if needed. After the PulseTech charger has desulfated the battery and the impedance has been lowered to a viable level should the specific gravity be balanced. Also I feel like I need to say I’m not a battery scam artist nor am I affiliated with one. Don’t ever put anything in a lead acid battery except distilled water or sulfuric acid. There are no secrets and lead acid batteries have been around a very long time and haven’t changed. The book “The Automobile Storage Battery, its care and repair” can be found on Google books and elsewhere. It’s known as the Whitte battery manual so named after O. A. Whitte chief engineer American Bureau of Engineering.
Great Job Ivan, I like all your videos. Wish more mechanics were like you, actually mechanics.
Ivan, you are making mechanics look really bad. LOL Seriously, you are empowering the rest of us DIYers to fix their cars cheaply and correctly. Keep up the great work!
I love how you always take what the customer tells you with a grain of salt and what other shops have done with almost complete questioning.
Sadly, you have too.
Ivan, You are absolutely right about "smart" battery testers. They are garbage! Many years ago I bought a battery at my Toyota dealer. When I got home I noticed the Voltage was below 12.3 volts after a proper charge cycle. That is not normal, it should be at least 12.6 Volt with a new battery (Lead-acid). I went to the dealer and told them I want a new battery because this was damaged. The tested it with a "smart" tester that said the battery was OK. I was not happy with their finding!
After a week a had to visit a friend and the battery was totally dead! My friend took me to the dealer and i asked for the manager. He eventually told his staff to give me a new battery. The battery was a Toyota "economy" part i.e. crap quality. It worked for about two years. After that I bought a new Bosch battery over 10 years ago and it's still fine!
10 year old battery you need to play the lotto
Budget batteries of any brand have a life expectancy of two winters a better budget battery might last three.
A battery from the top premium range of a quality manufacturer such Yuasa, Bosch, Varta, or Exide should last seven to 10 years or more if the car electrics are doing their.job properly Smart battery testers do work they are actually very good at spotting a battery in the early stages of failure but should not be used as the only test, that needs a high amp load tester which draws a high enough current to suit the CCA of the battery.
Bosch is quality, say no more !!!.
Denso
Yes Bosch are brilliant
I was paying as I needed it, for a DIY account that I had setup on my Launch. Having access to just the wiring diagrams alone is a blessing. It's funny that my employer never asked me why I would ask him for $ every time I got stuck on a problem diagnostic. Until he sat with me one day while I was doing a diagnostic on his son's car and saw first had what ALLDATA could offer. And at a sensible cost option. Now the shop has its own account.
But yeah, these modern smart battery testers are not worth anything. Just get yourself one of those cheap, old school load testers. 2 or 3 tests with one of those will tell you everything you need to know about the battery's stability.
Pretty sad state of affairs in the auto repair and service industry. Hard to trust anybody to do the right thing anymore. At least we have good youtubers to help those of us who want to figure things out themselves. Thanks Ivan.
Techs are constantly rushed because of the flat rate pay system. People who are techs take a lot of heat. However, they are not the problem.
As soon as I saw that Monroe work on it.
My first thought was, as Eric would say, "That's your problem lady"
That's awesome! Someone was not paying attention to what they were unplugging. I have also been told my battery was fine when it was not. That happens when they don't want to honor the warranty.
It's not a warranty item
Research before doing anything is the only way to accomplish something properly. Great job!
I have an '05 Acura TL and my HFL is in the same spot and was the cause of my parasitic draw. I replaced it and have always been curious what failed inside it to cause it, but never bothered to open the old one.
Shops are getting terrible these days. I worked on an '05 Camry recently that had some oil leaks, including valve cover gasket and timing chain tensioner. Went to remove the coil packs - the bolts were practically welded into the valve cover. The spec on them is only 5 ft-lbs! The #3 cylinder (engine is 1 3 2 4) would not move, bolt eventually snapped off, and after removing the cover I could not even drill it out. It had been torqued down so hard it became one with the valve cover. That ignition coil was an aftermarket Duralast coil. Someone had replaced the coil - it was a local shop, the customer showed me the receipt - but the part number was for 2006 through 2009 Toyota Camry, and this was a 2005 Camry. The coil was about 2-3 mm too tall, so the tech torqued the everloviin' snot out of the bolt to get it to sit flush. Probably caused the gasket to fail early in the process. Junkyard valve cover + replacement OE Denso coil and all is well. What a dumb but costly mistake.
Customer probably gave him the wrong information on his car. So AutoZone gave him the actual part for the year the customer stated. As far as the mechanic . You take your chances.
@@2nickles647 Even if that was the case, there are several failed checks there. I scanned the car pre-repair and it tells me it's a 2005 Camry. The date on the door confirms that. The one lone non-Denso ignition coil is physical different and quite obviously does not fit. Why would that be? I looked up the part to check for properness, bingo. This is basic stuff here that should not be messed up. The right parts for the right car, it's not rocket surgery.
fwiw, the owner told me it was a 2005 Camry, so I doubt that's the reason. They've owned it since 2008 and provided the sale paperwork in a folder that included all the other past work. The owner was very aware. I've worked on cars that have seen the same shop before and they've had work orders in the glove box with parts that match Duralast on the car, and there's an Autozone in the plaza next to them.
Step 1 verify customer complaint. Always take what they say with a grain of salt. I once rewired a whole ground system on a Jeep Compass that the customer had told me they replaced the bulb and it still was not working. Being I had seen the same issue at least 10 times before I went ahead and cut the terminals off and put new ones on. Still no turn signal. Pulled th bulb out and it was clearly blown. I couldn't charge the customer for the ground repair and also prevented a problem that he was guaranteed to have. Always do your own diagnosis and start from the beginning.
yes don't believe a damb thing they say
Th kid at Monroe making 16 dollars an hour who disconnected the wrong harness was probably cooking hamburgers at McDonalds last week.
Yeah, and if he didn’t have access to service data or was being rushed through the job by a service manager that works on commission I can’t blame him. This is why I avoid chain repair shops.
Don’t be so sure of that one
My old boss hired his hack brother to work at our shop, he also taught automotive shop at the local college, I consistently had to repair his comebacks… I was taught to do the job correctly first… still repairing to this day at almost 69
😂
note to self - don't take a fancy honda with an electrical problem to the tire shop [monroe?] and expect anything but a fat bill.
Mine translated like this: don’t buy car with fancy modules
@@kellismith4329 agree, but I'm not sure how these days! can we even special order one with less than 30 random computers monitors and screens and electronics packages??
@@ericfrazer4736 not me, I just keep driving my old ones
the issue with the link unit is it the 3g towers have been shutdown so the cell modem keeps searching for towers but that can be upgraded as well
Wouldn't that be the Onstar unit and not the Bluetooth module?
@@johnt.848 if you replace the 3g modem with 4g lte sloves the problem

Good morning Ivan. Always great videos. My knee slowly healing. ALSO! You got one one more subscriber on your channel, my daughter. She is now taking advanced auto in high school. She knows how to use a OBD scanner, do a brake job and a multitude of other repairs and inspections. YIPPY. She doing this so she knows what a car is about and avoid being ripped off.
Everyone's failures keep you very busy. Great job as always.
Ya know, Ivan, some people don't have the ability or resources to do these repairs; it is because of you that I do. You have accurate data to complete your repairs. GREAT VIDEO!
The 2002 Avalon had a 220ma draw, and it took a week or more for the cranking to even get weak. A few hours to no crank is just nuts.
Yup battery was SPANKED haha
Trust nobody only trust Ivan 👌
He is a dying breed of mechanic. Honest, Smart and has great work arounds. If only there were more mechanics like him.
I don't know how you can keep your sanity with these totally insane cars you work on these days.
Another great video.
That’s hilarious because I’ve seen that same exact thing more than once. Everyone unplugs that same connector when trying to disable the hands free unit. They never go quite far enough to get to the actual connector they need to unplug 😂
Reliable service information made this fix possible.
Every one I have done was under floor console.
Location can change when old engineer retires and new one decides it’s better elsewhere. “Job Security “‼️
Some of this is basic Troubleshooting 101. Sure, it's good information to know what the last person who worked on it did, but always verify it yourself. At least then, your troubleshooting is valid.
Ivan, nice job- again! As you and others have said before: start with verifying customer complaint/ concern and finish by verifying the repair.
My old neighbor had a 99 Mazda 626 that a shop replaced a battery terminal with a screw on type and cut the wire which made it too short to have the 6 gauge cable attached to the body of the car. They used a much smaller 18 gauge wire attached to the point of the 6 gauge cable (which was attached to the body) to the body of the car as a body ground. Even a older car, the battery cable needs to be as big as possible for the body ground. It destroyed the PCM and other electronics on the car, including the fuel pump and fuel delivery system.
Anything with needing cell service with cars, I prefer to use an aftermarket system for that link system. Older cars don't have the modern radio systems for 4G and 5G service. Last time I had seen a 3G setup was maybe 12 years ago. Those no longer work.
600 likes in only one hour after posting this video, AWESOME Ivan!
To be a good tech in this day and age, it would appear one needs to be an electrical engineer. The failure of all these modules is the reason we will never see these cars in a Meacum auto auction 40 years from now.
Yep, they do not belong there and ensure the cars will need replacing
I disagree. You need a mechanic that is willing to learn.
Love the way you always strive to verify the customer complaint and not just assume.
Never ASS U ME, assuming something can make an ass of you and me!😅😅
Ha, very funny Car Wizard just released a car video with Acura MDX as well. What a coincidence, just funny but not for a dead battery. Ivan, I like the fact that you do not trust anybody, what they say. I check it for yourself to be sure. Fantastic.
I always check the Reserve Capacity (RC) rating of batteries I am considering buying for my car. It's a good thing to know if your alternator fails or if you have a parasitic draw. "Commonly referred to as RC, reserve capacity is the amount of time, in minutes, that a 12V battery can run before dropping to 10.5V. It is measured in reserve minutes. For example, if a battery has a reserve capacity of 150, that means it can supply 25 amps for 150 minutes before the voltage drops to 10.5V."
When all is said and done, YOU followed the proper procedure, like you've done in the past, and there's the problem.
Good one Ivan.
Nice straight forward diag. Battery load test using the headlights is now part of my toolkit. Thermal image was a compelling visual image. Thanks for sharing.
Incompetence everywhere. Well done Ivan. Thanks!
Supposedly, the "high-tech" battery testers are load-testing a battery on a very short-term basis by pulsing a semiconductor like a MOSFET and measuring instantaneous current and voltage values. Problem is, the internal resistance of a good car battery is quite low in comparison to the connections that are made to the tester. It's amazing these testers ever work well at all. Just like so many things, the emphasis has been on eliminating hardware, and enhancing the software used by the microprocessors that supposedly analyze the battery. The temptation is to "program around" deficiencies and make it work, and that's what the manufacturers try to do. Good call on your part!!!!
I don't see any value to the fancy battery testers when the car can perform a real-world battery capacity and current test by itself with no tools required haha
Yessiree...and you can read and get tips all day long but without a good foundation of experience...you will still be limited in abilities to diagnose. As in this video, Ivan had way more experience and fixed this concern in just a few minutes plus, along the way he found the new battery is very limited and should be replaced.
Fantastic Ivan, you are the best and i mean it, i watch every video, thank you, i wish you are in Australia 😃
One thing that you didn't show at the end: definitely don't try to start the car while you still have your amp meter hooked up.
The way you edited the video, it made it look like you had the amp meter hooked up the entire time. :)
Man I've had a lot of hands free modules cause draws on all manufacturers. Mazda just yesterday. I've had good results with the Mitsubishi's and Kia's by doing a hard reset and clearing out the numerous unused phones registered in the bluetooth system with no return draw. But those were my family's vehicles and that's iffy on a customer's vehicle you don't want to return.
Thanks for the video Ivan.
Great job as always. 👍👍
Congrats is highly in order for being able to spot that misdemeanor. Only a very expert tech would have found that anomaly. After every video, my assessment of your expertise goes up a notch. The total grasp of some amazing difficult scenarios never ceases to astound my brain. Keep up the good work and we thank God for your talents.
On a 2000 Yukon XL I had the OnStar module draining the battery. I just pulled the fuse for the roof lighting circuit which powered only the OnStar unit. Thanks Ivan!
To all that read these, the cellular network keeps advancing and leaving the older vehicles without the accessories. There is also no way to upgrade them. What a niche market for some upstart company.
Ivan, I've watched your videos for years, buddy you are one amazing tech. Hands down the best I've ever seen. I know if I ever have an issue with my two Toyotas you'll be the one I call.
Thanks Dan from WV USA
Impressive Diagnosis ivan
Good job Ivan!
Thx Ivan. Because of this vid I revisited a draw problem I have been having on my 05 TL. 3 yrs ago, I tried to chase down a large draw on that same 7.5 amp fuse. The diagrams i had from Mitchel did not show the WiFi on that same circuit, just the interior lights, overhead controls, and remote signal controls, IE key fob signals. Indeed, after pulling said fuse, there was n/p, but several systems didn't work. After looking at your vid, I decided to look into it further. Sure enough there was a module buried in that overhead console by the headliner with the GREEN connector! I unplugged that, and battery draw was down to .018 amps after about 10 mins. What i cannot explain is that the garage door opener, automatic seat positions, and alot more still retained their memory and functions w/o me doing anything. Do you think they get stored in the bcm? So 3 yrs later, everything works but the hands free. But let's face it, few phones will pair with that old system anyways. Thx again!
THANKS IVAN, FOR THE GREAT VIDEO/INFORMATION ON HOW TO TELL THE BATTERY IS BAD WITH SIMPLE CHECKS SO U PUT UR METER ON AMPS NOT ON MA TO CHECK THE DRAW.
Good one. Always have to verify the hearsay before you believe anything.
Great job as always. To bad you can not "clone" yourself to other parts of the country. Technicians of your caliber and integrity are sorely needed!
I’m blown away by the awesome data Alldata has for that Acura. For the VW’s I’ve looked up in Alldata, there’s never any photographs, or even diagrams showing where the components are physically located.
Nice work Ivan. I like your hood prop lol
Classic weak hood struts 😂
Probably said it before when you buy a vehicle (new/used) get a repair manual.Cheers Ivan .
This screw up at the shop makes it had from people to trust auto repair shops and even the dealer shops. Too many unnecessary bells and whistles on these new cars.
What?????
Brilliant, as usual.
Ivan for the win once again! That was a quick video.
All they had to do was read! They were so close lol Good one Ivan!
Mechanics don't need to read anything...they already know it all haha!!
Well experieced technicians make well satisfied customers,,,,100% 🎉🎉🎉
Great fixed another, wish you lived in Sheffield UK.
Aside, from the hands free module. One of the best vehicles that Honda ever made!!!
I got the 2005 model... Radiator transmission line inlet and outlet corrode over time.
I got an aftermarket cooler and temp valve and bypassed the OEM cooler on the radiator itself.
This happens to the 3rd generation as well (2007+) as noted on MDX/pilot /Odyssey owner forums
Also look for a component that’s not working 1st (it’s usually the Rear Wiper Motor), this will be a good clue as to why the battery dies overnight.
Nice fix Ivan.
That's why you verify your repair.
Just cause you unplugged something, doesn't mean it's fixed
ACURA = Automobiles Causing Users Repair Anxiety 😂🤦♂️😂
LoL
That's a good one lol
I apply at Monroe back in 2019, they pay techs on commission pay. Base pay was around 10 bucks + commission + small percentage on any upsale. The lead tech was bragging about doing front brakes in under 30 minutes 😮.
Thank you for the video
Mama always told me stupid is as stupid does.
I used to drive those things around with 2 miles on them... Crazy they are 18 years old now 😂
Do you have a video on how to clean a rear camera on a ford expedition platinum 2016
Love the logic :D
well sorted ivan and i agree with all the comments below me, same crap garages here in the uk only after the money 75% dont know what they are doing
Well done Ivan :-D
Odd that the ignition switch output didn't go through a fuse to the overhead module.
Not ideal but the power would get there, or a relay....... ha ha im relay crazy :-D.
Dam silly designs.
What can you say. Did the shop put a newbie on this ? Or does it take a seasoned pro like Ivan to properly do the repair ?
I would fully recharge the battery & get a conclusive amp hour reading on my battery load tester which has been very handy for me when I had to diagnose a slow cranking issue in my car which had am issue with the starter motor solenoid.
The battery in my car is 3 1/2 years old & still reads between 600 & 700 CCA when it's rated at 640 CCA.
I would also recharge the battery prior to testing it with a load tester just to rule out a possible issue with the charging system or the battery itself.
Yes,my cars battery will start the engine 10 minutes after the high beam headlamps have been turned on,I don't always get a Mate either because I don't marry one of them who had an argument with our local auto electrician when the battery light turned on in her car & he diagnosed it as a bad alternator which it was.
She thought that she knew better & tried to tell him that the battery needed replacing when it didn't, one of their Reids said that the person who trained me would have to tell me why I wasn't for her over 20 years ago !
Nice NPR as the battery was already spanked. A few long weekends discharging .2 amps in the winter will lead to no starts in short⚡ order!
its almost like you are from Missouri the show me state after i see it i will believe it i like the old fashion battery testr load coil resistant boxes always served me well for testing battery's some of the newer battery's are rated higher amperage than the od testers
I got a 2003 Jeep Liberty with a parasitic draw, other people tried to trouble shoot it, but missed the fact that the radio was turned on. You couldn't tell if it was on or off because there is no light.
Meaning you could listen to the radio with the key removed?
And Hondas have the A/C relay that gets stuck, that is causing this draw. My wife's '09 CRV just had that issue.
But how can that be if it was done according to your video? 😂 🇺🇸
I have a 2005 Acura TL and I’ve never initiated the Bluetooth device in the car so it’s still fine
no bonus footage? now i'm sad
great diag, ur getting eurotrash back on the road one at a time !😁
I worked Honda for years. AC relay sticks or blue tooth
Own an Acura? Better call Ivan!
Then a psychiatrist to get your head examined
WTH is a "Monroe" ? Maybe a "Buchanan" woulda guessed right, on what to unplug.🤣🏁
@10;20, It is hard to soar with the eagles when you are dealing with turkeys
Keep making videos great videos
Great diagnostic strategy, Ivan! Yep, without Alldata information, you might be looking for the HFL in the center console, or something. The level of ignorance of many auto-shops is worrisome.
Another easy battery test if ya don't have a fancy carbon pile tester is fully charge the battery than disable the engine from starting record cranking voltage should stay above 9.5 volts for 15 seconds I like to see 10 volts or higher
Love it .
Use the vehicle lights as a load tester .
One less tool to purchase !❤❤
Thanks Ivan 👍
On diesels the glow plugs make a pretty good load test
Amazing when you unplug the correct thing! LOL
Ivan if the hands free link unit is replaced, will there still be a parasitic draw?
Maybe because that technology for this vehicle is outdated
Awesome
Pretty nuts.
Battery would have been fine when tested but every time a modern battery gets deep discharged and charges back up the AH charge capacity gets reduced so on a car with a parasitic draw even what starts out as good battery gets quickly turned to toast
Electronic smart testers are actually pretty good for spotting batteries with issues early on I now use one as my main tester instead of my high amp voltage drop tester because here in Europe cars 2 Litres or over are diesel and have really big batteries and need a very high amp load tester to match.
10/10
Car Guru Ivan . 🛠 💻
*_Extreme common battery drain problem_*
I can attest to the fact that the digital battery testers are junk. Twice had a shop and a parts store use them and was told battery was good. But put a good old fashioned load tester on it and as the load was applied you could watch the voltage drop clear to 10.5 volts. Its sad that dealerships and parts stores rely on these junk digital testers.
It's a way to sell more batteries. Such as the case where the auto parts stores sell parts.
Customer wants a diagnostic check because their car is acting up. The parts guy plugs in their scanner. The kid at the counter says...o it's this. Customer buys the parts. Next day..same problem...wants a new part...done deal. Still not fixed. Told to take it to a shop for actual diagnosis. Customer says no because of the cost😅😅😅
