Ever work on a car and it gets the best of you to the point you just say, "that's it I quit!" That's what happened on this Hemi Dodge Ram that came in with no 4x4 and the neutral light lit up. No info and service data, no codes and boom it fixes itself and I don't have an answer....

Found her door. Evidently the four wheel drive light is on. You gotta check that baby out. Oh, seat's moving on.

It's all going on. Uh, let's see I Just oops. don't move the seat because it just makes a crutches out. Service: Four Wheel Drive I Saw it pop up there.

but oh, his neutral light isn't it? Yeah, nothing's happening here. By changing the shifter in here, let's do this. Foreign pops up there in the middle it says Service four wheel drive and then it goes right out. Oh there it said.

ESP Bas I had the mind of its own. Let me just do it without starting it. See what it does? Interesting, yeah. Service: Four wheel drive.

But yeah, it's just very, very brief. Take it for a little two and see if that does any. and I don't know. the lights pop on here when we drive it.

it's definitely not in four-wheel drive. be Crow Hopping Pretty matter on these. Corners If it was only knock in four-wheel drive. Okay, so the red neutral light is on.

that's pretty much all we've got to go on. red neutral light and then a brief service Four-wheel Drive message: Go back and see what it has in it For codes, we're going to use the uh White Tech here because we have one and I let that get all hooked up here. I'm quite aware of my email address up here at the Spam email address so you can email your little hearts out there. Uh, let's see says it only has one code so let's check that out and see what it is.

Driver mirror heater control circuit shorted the battery open in the door module. Well, that's not. uh, very useful to us is it? Uh so the four wheel drive on a Chrysler Wow, this is kind of unusual for Dodge Usually you plug in there, everything's lit up. lots of code so it should be here.

Drivetrain Control module right? I Think that's the four wheel drive? Uh, let's see says there's an update on it. Um I don't know what the update is for? Oh no. I'm sorry. it is up to date.

Okay, so that's the new part number current part number: Okay, so there is no I didn't think it I saw the little Mark on on Dodge as if it has a flash available. It puts a little lightning bolt next to it. So our our module is up to date. Um says there's no code so that's quite unusual.

Let's look through some data. Let's kind of check some stuff that's interesting. Transfer case Status neutral: It thinks it's a neutral. Hmm, so that's that's pretty weird.

Service indicator: request fault so let me just shut the key off. Just kind of curious here. so key off on true false. Okay, so it does kind of blip at briefly and I don't know if that's a product of you know, just the algorithm, just how it, how it is.

Um, so that that's interesting. Okay, let's just see if we uh see if we, see anything else in here that gives us any kind of indication of anything. Transfer case, position sensor voltage. Okay, neutral lamp request is on.

All right. So we maybe we can find a chart that gives us our transfer case position sensor voltage outputs. You know, perhaps we just have a transfer case sensor that's skewed. Um, you know, a position sensor even though we're in clearly in two-wheel drive.

All right. So front axle is disconnected, which we knew that um, no. Dtc's just kind of going down. We just want to look to see see if we see anything.

It's quite unusual. I don't know I didn't see anything on here for the switch input. You know, the switch down here on the dash I don't see that right off. anyways.

I just kind of want to look. and then as far as neutral, it just has the button here. Well, that button just felt kind of sticky. Oh no.

I guess it's not so I put the actual Transmission in neutral here and see if anything, see if anything changes. just push and hold this neutral button. Okay, I just put it neutral. push the neutral button and now everything's working.

Yeah, hear it out there shifting. so that's really kind of bizarre. But yeah, let me show you here folks. So now I find a dash for Auto Four wheel Drive Foreign.

Go back to two wheel drive. So that's kind of bizarre I wonder why I did that? So now the transfer case is actually in neutral I Just you know, put the actual transfer case in neutral and we can see the transfer case position. sensor voltage is 1.8 So now we'll take it out of neutral here. put it in the two wheel drive transfer case.

Voltage is two point nine, eight sensor voltage. Huh? Yeah. I mean I can hear it all there shifting just fine. So uh, clearly it's working as it should now.

which is kind of Biz I don't know why it was goofed up. Let's just start it and see if we get that light again. ESP Bas I Guess we can just check it right here to see if it, see if that's something normal so it says false. Okay, so that must be normal, must be like a bulb.

Check it does. Okay, so that's always something worthy to note. Yeah I don't know. fixed.

You're just stuck in some kind of funk here. Yeah. I I don't know. That's kind of uh, kind of.

Bizarro I think what? I'll do I mean this is a stupid video at this point. but uh I think what I'll do is I'll just do some poking through service day to see if there's any service bulletins anything like that. but I don't know why it was stuck there with the neutral light on when it seems to shift it I don't know is what it is I guess well I don't really have any advice for you folks I Was looking under the Uh Theory and operation here I Went through all the star cases, the service bulletins. there's nothing nothing really published on it.

Didn't find anybody else having this issue. Uh, you know it makes a note here that no LEDs illuminated illuminated indicate a fault in the transfer case control system. Uh, and if you read through here, it indicates you know that the light will continue to indefinitely flash if it hasn't completed a shift. I mean it gives us some specs on our switches, but nothing really.

uh, indicating you know, just your neutral light on and you know it's clearly in two-wheel drive. So uh, don't really know where to go from here when everything seems to function now. sometimes cars are just stupid and that's what we're gonna chalk this one up to. So I think we've done our due diligence.

I'm going to close out the scan tool here like I said I even poked uh like on Identifix looking for some silver bullets to see if somebody else has come across this and wasn't anything published. So let's um, I'm just gonna take her for it too. We'll do some four wheel drive shifts and then we'll give it back to them I Did talk to the customer uh, briefly and he told me that you know he didn't try to put the transfer case neutral. He didn't didn't try anything.

He just went to use four Wheel Drive one day and noticed that it wouldn't go in and notice that that light was on. But for how long? who knows he's the only driver of the truck. No kids, No, nobody else drives it. So yeah, let me hold this.

I Don't know. You want to go inside? Yeah, she looked like a little homeless chair. There you go inside. we're going for a rep.

Hey, there we go. The lights on there. the lights on down here. it's just going to four.

Auto Splashing at us for auto has been achieved. Return your turn signal. here we go four Auto Works Four wheel Drive lot. All right, she's in four wheel peel.

We should be able to tell if it feels like it's binding up. Oh yeah, she's in four guys. Oh, we just came to a stop. We go back to two-wheel driver because this is what it is folks.

Well, we're not gonna make a mountain have a more hell. We'll just give it back to him like this until no problems found. In the words of Billy Currington got his great. Beer is good and cars are stupid I think it's something like that? I Could be wrong.

but don't you guys do me wrong by going into that comment section. Leave me a question. A comment, a concern. Tell me what you think was wrong with it.

Give me your theory. You guys are always good at giving me the theory. So go down there and give me your theory. and uh, just remember.

Oh insty Facebook I mess up my hand signals again, that's for sure just for my reviewers. If I can do it, you can do it. Thanks for watching.
