2011 chevrolet, it's equinox has a battery draw intermittently. We can see about every four minutes. This thing pulls about 70 milliamps on average, and it's been doing this. I've had it hooked up for about an hour and it's pretty consistent every four minutes.

Otherwise, it sits resting here about 10 milliamps. I see all this hash down here on the screen. That's from the security light here on the dash - i don't know if you guys will see it, but it blinks there and uh. You know if we change the speed on this.

It just looks hashy like the hash slinging slasher from spongebob uh. If we stick it here, you can see you know every time that light beeps turns on lights, don't beep you ding dong, but uh we'll get here. Let's get it here where we can see, that's not so cruddy, but every time light flashes. So that's why we see when we slow it down to you know five minutes you'll see that it looks like it's.

You know a lot of hysteria. So how do you fix that? What i'm hoping for is i'm hoping service date is right. So gm has a service bolt now or a pip uh. They call it on this little guy uh engine craig no start to do to discharge battery parasitic current draw and i always check service bulletins, because you never know - and here it says uh.

This may be due to an hvac control module intermittently waking up and creating a 70 milliamp drop, and i think we'll see i'll wait for it to go back into a draw over there and we'll see it is around 70 milliamps um. It wants us to check and see if 70 milliamp draw is consistent. If it's not uh pull the hvac bat 20 amp fuse number 12. Locating the instrument panel wait for it to go to sleep, see if it's eliminated and they have an updated software for it.

So that'll be really interesting. I've never run across this, and if this fixes it, i never would have been able to find it efficiently without some service data. So, let's see i'll wait for this going to draw again i'll show you guys what it's doing and then we'll uh we'll do one of these we'll cross our little nuggets and pull that out and see if it's there. She goes folks so she's about 70 million 69er ish when it light blinks so 66 to 69er uh, and then it goes on for a short period of time here and then it'll turn back off and then go back down to 10 milliamps and it continues the Cycle about every four minutes, so i'm curious to know if this surface bolt and apply so uh, let's yank out the fuse we're on the passenger side foot.

Well, it's an hvac battery, which i saw here, number 12. number 12 goes. I figured i always got to figure out the maze folks uh 10. 11 12..

So it is, let's see where we got one two three four up one, two three four is a 20 ampere. Oh, she comes we'll do that right here, we'll close the door lock. Everything up and redo our test, all right, we'll make sure she's locked, because you kind of try to leave the car like the customer would leave it uh. Evidently, this car sits a lot.

She tells me sad all winter, but they were having this problem prior to it sitting this winter, so there we've got that we're gon na we're back in line well, of course, now we're well over 200 milliamps we'll go up to our 10 amp scale. Right now. We're drawing about a half an amp, so after this car goes to sleep in about 10 minutes, i've discovered so we're going to set it. I'm going to put it back on the 100 milliamp scale, because i really don't care what happens above and beyond that and i'll.

Let this go and then we'll come back and check it, we'll let it do a full five minute sweep after it drops down to 10 milliamps and see if that problem has been fixed. I finally went to sleep. I almost went to sleep waiting for it to go to sleep uh. What we'll do we'll just start a fresh screen here and then we wait.

Gotcha tell me what making you coffee watching facebook watching facebook? How do you know? I was looking for a gift for you, a gif, a gif or a gift, a gift for what saying my birthday. Just because i love you wait. I did, i don't think they're tall enough, no, probably not i'm so tired. Today, it's only 9 15..

I'm like this, my mother, i'm like you know you know how you get when you get like that. What are you doing waiting? Yes, like every time i drive more than 15 minutes yeah. I can't i hear yeah. I hear you sometimes driving to work.

I'm like i wish they had a rest area in this eight miles. You know what my eight mile drive to work. What are you doing waiting for results? You haven't figured out yet almost maybe i'll come in and go out in a little while, if i do, are you gon na froth, my milk, with your frother? This is all the hair's too hot. You don't have a pour over.

I really prefer pour over here. No get out of here all right, we'll be back. We better go see where we're at hey. Look at that.

We filled almost a full five minutes. Let's see what it's doing anything funny! Oh we dipped. We might have fixed it because, usually within a five minute period like i say it was pretty consistent every four minutes. What time is it now 109 on here? It's not irl, so we'll uh keep a note where that little height spike.

There is not a big deal, we'll come back here in about four minutes and see if it did anything, then to be definitive. I guess we could stick that fuse back in and the draw should come back. Let's see, what's it been 9. 10.

11. 12. 13.. It's four minutes see our mark.

There's moved over and no high action, like i say just the hysteria here, which is just the light flashing every time, a little light bleeps on there on the dash on on yeah, i'm not real good. At timing, i'm trying to look at two things at once, but yeah every time that little light flickers. You know you get that which is normal to be expected. So, let's throw the fuse back in it and make 100 sure we're correct fuse is back in it and we're sitting at a steady 407, something milliamps 200 and it gets down to this 171 milliamps, pretty quick! So we'll! Let it sit here, and i do believe uh that i was even when i was waiting for timeout.

I was seeing it turn on every four minutes on top of the 170 milliamp draw, so maybe, instead of waiting, you know for it to fully die down. We'll see what happens here in a four minute period, and we should see you know uh 70 amps on top of that plenty of time has lapsed and now no draw with the fuse back in ah, but i got a confession when i was down yonder here In the chattahoochee looking for the ho chi kuchi in the fuse box, i noticed this after market wiring son of a mother, and i said you know what i'm right here before we go yank out the fuses out of the hvac. I said. Let me yank these two fuses out now who the heck knows where they go to just some kind of aftermarket crap, not a remote start.

There's something tapped in so i feel like i've lied to you and now i'm being exposed. So what i need to do is set you down and i know it was going to give us some inconclusive results on a test if this had to be the draw. But i was thinking boy we're really onto something with that 70 milliampere. So i'm going to stick them back in, even though i don't know where they go.

Just this red blue wire that goes somewhere is this way, which you can tell a real pro put these in got some vampire clamps, black and red wire and a pink wire which are two predominantly colors in a gm that are power. They go somewheres up here. Up so like an idiot, we got ta. Do this again.

Anyhow, sorry for lying to you didn't really lie. I just didn't disclose the whole story. I just figured hey while you're down there fella and you see that monkey business just yank them out. I didn't think that they would be connected to anything that would cause an intermittent draw and it fit the criteria way too.

Well, with that whole hvac module thing and who knows maybe by removing the fuse from the hvac module and plugging it back in, got it out of its crazy loop. But now it seems kind of weird to me because they did say they put a battery in it. You know i had the same results and we wait well i'm waiting for this little guy to time out, given that it's five minutes to see if it repeats itself now uh, i'm firing up the old tecline connect, letting her go through updates. I think i'm gon na go through and update the hvac module just because uh it fit the criteria way too well, and perhaps you know removing the fuse from the hvac module putting it back in.

You know reset it so to speak. I've never ran across this. On one of these cars, but it just seemed to fit the criteria like you know, to a t, and i'm going to talk to the customer about those about the aftermarket wiring. I doubt the lady even knows about it.

I know she's only had this car for a couple years - um - maybe it was a buy here. Pay here thing had a you know, a gps track or something on it. So i think what we'll do i'm gon na talk with her? If she knows nothing about the aftermarket stuff, we're gon na leave those fuses out, because you know clearly it doesn't seem to affect it and then we're going to go through and do the update on the hvac module and possibly the bcm, because they also had a Battery draw concern for the body control module, but i don't think it didn't really fit our criteria: okay, equinox uh, 2g nal at the beginning of the event, yep, that's right: okay, yeah i've got some mickey mouse wiring under the dash, and i don't think the sunroof Is factory that could be wrong? It does all except sunroof. It was not factory, so no sunroof from the factory correct! Okay! Thank you, sir yep battery boom low battery, she says burn around the hook.

I was curious where them wires go and i see they go up, so i unhooked them and i said well something ain't going to work. So i looked up and i said you know what something right. I don't think that sunroof's factory and sure is sugar. The sunroof didn't work, guess what i put the fuses in the sunroof works, so those fuses are for the aftermarket sunroof, so we're going to leave them in and we're not going to call the lady we're still going to update the hvac control module.

Now those are hooked to a full-time power and then a key on source. So i doubt there's any kind of monkey business going on up there on the sunroof area. It does function. I did open and close it, but, like i said i could tell it's not an oem gm sunroof, so i just double checked with the dealer per vin.

I didn't see it listed on the build sheet and i just wanted to be sure it wasn't reading it wrong. So we're going to proceed with programming, the hvac module and then i'm going to charge the battery and give it back to the lady and then i'll get back to you in a few months. If i'm wrong so yeah, it's got your classic aftermarket hole in the roof, they did a decent job on it, but i knew it wasn't. It wasn't the og i could tell by the switch uh but, like i say it functions, fine, so i don't want to throw it because you know aftermarket crap is but yeah when yank the fuse is out.

She quits so anyhow keys on. Let's update the hvac. If it needs an update, hopefully so this is pretty interesting. Folks uh, i don't see the hvac control module listed body mod, joe ubcn inertia, cluster, there's no hvac module listed.

I just double checked the service bulletin and the rpo code fits this completely um. This shouldn't make a difference. We got 11 equinox selected um. So that's kind of bizarre.

Why do we not show the hvac control module? Just this remote heat? That's air conditioning control module. I don't think, that's it! Folks! I'm going to pop back into gdi. I mean it should be listed under the hvac control module. I don't want this to take up one of my slots.

I don't want to pay for it. If you don't have to um, i'm going to go back in to the gds and see make sure gm calls it. The 8 fact module. I mean that's pretty clear on the service bolts and that's what they're calling it but um to pop back into the factory scan tool, and indeed it is not an hvac module on this uh.

It is a remote heating and air conditioning control module. So uh, like i said, rpo code and everything matches, i don't know what it was. Let's see something here: c67 charlie six, seven was our rpo code which fit the tech service bulletin. So it's weird because they clearly caught an hvac module.

I can't say i've ever seen a remote heater air conditioning mod, or at least, if i have i've, never paid attention to it. I did pop in there and look the last time it was programmed was back in 2010, so must be when this car was new. So it should have an update. Foolishly, i didn't look to see if it did and it does so.

Thankfully it does have an update uh. It's actually had a couple updates since um, since the start of it says, there's no bolton available which is kind of curious, but here's your current part numbers, here's a new part number. You know all three portions of it are being updated, so we're going to take and let that go ahead and do its update here. Uh we'll take and double check.

I'm gon na double check the dcm update. I don't think that applies to this car. There was some of these cars apparently uh that have the wrong programming in the bcm that allowed the backlighting on the dash to stay on even after the key was off. So i doubt we're having uh.

You know any update there because you know clearly the back lighting shuts off so i'll. Let this go through, do its thing and then i'm gon na go back in hvac module, relearn the hvac doors or see. If there's any programming there, we could look on service data to see what we have to do and then we'll take it from there folks. So if i followed my own advice, i would have looked first under control module references.

You guys remember that from a previous video, when you want to know, what's going on with gm, how to set up a module, so under hvac control system or hvac system control, module, programming and setup, they clearly call it the remote heater and air conditioning control module. So, even though we refer to it as a generic hvac module, even they call it an hvac module under sps under our programming, it's called the remote heater and air conditioning control module. It makes you want to jump off a building anyhow uh. It just tells us to go ahead and uh do an update on it.

Follow on screen instructions, clear the codes and then i think it says if there's an actuator replaced, we have to recalibrate them, so we should be good just doing the update it's taking forever. I got so much support, freaking lowered it out here, she's loaded. We got another equinox out there. I think it is air tubes are plugged up on it.

Yeah chevy i put a motor in about three years ago, she's clattering. Now so i got a warranty job. The v-dub another chevy another junk forward. I got ta, get cranking pretty calm in here, comb, your hair, it's pretty poofy! Today, okay, she is done programming.

Finally, we're gon na exit out of here, i'm gon na exit out of here. Let that i'm going to shut the key off, so i left the key off for a little bit now we're going to hop back in the scan tool here and we're just going to go in we've got a. We probably got a bunch of code set and a bunch of modules. Let me see when the inspection comes out.

Okay, we're good! I didn't want to clear any codes if the uh, you know if the inspection is due here. Oh hey, there click happy fella, we'll go to vehicle diagnostics. Uh we'll go to vehicle dtc. This should do a full system scan because sometimes when you program a module, it takes all the other modules offline and then it will set a host of codes in them and you can clear them right from the programming screen, but sometimes it doesn't get them all.

So i find it's best just to go in with a scan tool. You know either this or you know i'll tell or whatever you have do a full system scan kind of wipe all the codes out of it and i think, just to be on the safe side, we're going to go into the hvac module or the remote control Heater hoopty dupty and we're going to take and just do an hvac uh relearn on that. Yes, we got a bunch of codes here. We can take a quick peek here and see what they are.

Some low voltage codes, low voltage, low voltage yeah. These are all history codes, we're going to take and clear everything out so, like i say this car they did say was sitting all winter. They didn't drive it for months and months and months, because it's two-wheel drive and they live out in the middle of nowheres, which is basically everywhere around here. So we're going to clear all these out.

All these low voltage codes then we'll pop back in to the hvac module. So that's all done we'll, let it refresh here and now we should have green. We have green chucky boxes on everything, so that's good, no codes in the modules and then we'll go back. One more time go to modules, we'll find this remote control here, we'll go to configuration reset we'll do the actuator learn process see what that's all about just to make sure everybody's cool there's some clicking and some snapping going on in there hey? What do you know? It's another youtuber turn ignition off and then back on.

Let's see turn that down. You can't hear that let's go to continue clear dtc's, it says so, let's see hit the back arrow we're going to see if we have any codes in it, no code store. So it says it has no code so fantastic and that shouldn't have set codes in anything else. Now, if we go on data display, we should see an update, not data display id information.

We should see that we updated it today there. It is so there's our new update, so that's good. I think this is the best we can do folks um back back out. It did tell us to clear the codes, but i'm assuming in this module.

I don't think we're gon na have set any codes in any other modules, but it only takes a second to check. So we will do that. Real quick, like a bunny, wasted way too much time on this today, should have been working on something else, but that's all right live and learn. Okay, so no codes and nothing we're out of here get your computer's on the way.

There's power supply should never come in here, unplug, this little fella so make sure all the all the options work here: roll her up by defrost yep roller on the floor. Yep it's blowing on the floor, make sure we either restart the door yep. I can hear the change there. I just did hear some clicking and stuff when it was going through its recalibration, so i want to make sure there's not a mode door or anything, that's going kind of wonky on it.

So i just wanted to run each one of the doors to their extreme yeah see. I just heard some clicking there. Let's see, let's put her on the foot: let's go back to hot yeah, a little bit of clicking on the hot cold door. Yeah sounds like some plastic getting ready to break awesome.

I'm just gon na wait for this time out. Folks uh, it's already been almost five minutes and it's running pretty steady at 168 milliamps. I know after 10 minutes it'll drop down. I do know prior to pulling the hvac fuse out that i would see like i said, i would see that 70 milliamp spike on top of whatever its normal draw, was waiting for timeout or after it was timed out.

So it'd say: 170 go to 240 or was sitting at 10 and would go to 80.. Should i have fiddled with the aftermarket fuses over there and not told you? No, i shouldn't have that's what i should have done, don't touch it, but i seen it. I had to touch it uh. The good news is so i did find out what they went to, which was the aftermarket sunroof once i seen them running up and being that that has no auto functions or anything funky on i'm assuming it is just a you know: full-time power and the kion.

I'm not assuming i know that's what those two powers are uh, but i don't think that has any type of logic or anything that can really you know, wake up and and make any sort of draw. So i'm not super concerned uh with that. It is quite interesting that this fit the criteria of that service bulletin. You know almost to the t almost exactly to the amount of amperage it was drawing and then, after removing that hvac fuse and testing it it.

You know our draw mysteriously went away and putting it back in and didn't come back. So the only thing i could do at that point is update the hvac module, as suggested by the you know, service bulletin, and then we wait i'll give it back to the customer uh. Let them know what we did. Let them know that we, you know, found this bulletin and so on and so forth.

So let me know what you think and i want to find you down in that comment section the questions, the concerns you have, the inste, the facebook. You guys know what to do. I'm done telling you go down there and just show our beers. If i can do it, you can do it thanks for watching.
