Fog lights with high beams

[Jimmy07]

But wouldn’t Chrysler’s computer diagnostics be able to tell something was different?

Both the aev procal and the AlfaOBD operate the same way- they turn features on or off, and change values that already exist in the BCM. It’s just that the AlfaOBD can do FAR more than the procal for a little less money.
FCA would have to purposely be looking for a specific change in the BCM in order to notice it, and even if they seen “hey, the fog light dropout is disabled”, they’re not going to do anything, because it doesn’t affect anything else. FCA themselves built the feature into the BCM to be enabled or disabled. It’s just that they can’t allow themselves to change it on a customers truck because of the US laws regarding high beams and fog lights.

Well, I don’t doubt that the Alpha can do a lot more than that other thing but I thought the whole point with the AEV was that it doesn’t require the bypassing of the security module.....

Any device you use on your 2018 requires a bypass. If you had a check engine light, you can’t even clear a code with a scan tool without a bypass.

Hell if I know, I don't have one and from what I can tell through limited research, no.

Oh... so then I’ll have to revert back to my original statement about if I were interested enough to have my fog lights stay on with my high beams, I’d just be better off with the relay-way instead of using some electronic device.

Well, if that security module has to be bypassed in order for those things to work, they’ll definitely know it.

It all depends what it’s worth doing to you. If warranty is your biggest concern, and you wire in relays, that is a sure fire excuse for them for a warranty claim denial if the problem has to do with anything electrical. Also, the above method described by leroys73 wouldn’t work. The factory fog light switch would have to be taken out of the equation, since it sends a MUX signal to the BCM to turn them on. You would have to put the fogs on a separate switch. The AlfaOBD software, interface, and bypass harness (easily removable) can be had for ~$160. Then you have an invaluable tool for reading AND clearing codes, adding any future factory options, programming key fobs, etc.

I guess it should be explained what the actual purpose of the security gateway is. It only allows devices that are plugged into the OBD port to read info, and not change info, including clearing trouble codes. It is not there to keep you from accessing the modules, but to prevent others from accessing the modules through the radio and making changes while you’re driving. If you give someone long enough, they could figure out what canbus message code is sent that operates the brakes, and they could replicate that message and send it through the radio to the abs module. They don’t care that you bypass it for yourself. Any changes that you make are the same changes they would make with their tool, such as adding factory remote start, or installing tow mirrors. It’s just, when they do it, the sales code option is updated and added to your VIN option list.
The bypass from M2mods gets installed in about 2 minutes, then when done, can be removed in about a minute. There’s no way they can even tell it was ever even used.

Just for reference, I have the fog lights dropout disabled and many many other things with AlfaOBD and when I took my truck to the dealer for the recalls they flashed whatever they needed and my changes were not effected, they never said a thing.

Thanks for that explanation. But here’s the million dollar question- in order to keep the settings you make with that alpha thing, does that security bypass need to stay connected? So in other words- since there would only be a few things I’d be considering changing; having the fog light cutoff taken out would be nice, but once I change, I can hook the security module back up and have my changes stick? I can’t leave this module unplugged, can I? I read long time ago that if it was left unplugged, that you can access your truck’s PCM. So if that’s true, that’s what’s not made me want one of those because if i need work done, I’d have to have that module plugged in and quite frankly, I don’t wanna have to be ripping the dash apart all the time, and removing that big radio just to get to the module- because yeah, that’s where it is, correct? Conveniently located behind all that?...lol.

They may have never said nothin to you, but what’s stopping them from “noting” something down somewhere that you have a whole bunch of things enabled that may or may not necessarily need/should be enabled, for future reference? I dunno, maybe they didn’t, but I’m just pointing out that who knows what all goes on behind closed doors.

But are you under warranty, and is your truck new enough to have that security module to screw with?

My truck is a 2017 with less than 15k miles, only the 18’s got the security modules.

I refuse to live my life in fear of the dealerships or in fear of anything or any one.

That’s kinda what I thought. You don’t have that module to deal with this like I do. But hey, if I could only have two bypass that module one time just so that I can program, and make the changes that I want, and be able to hook that module back up and leave it hooked up, I would be fine with trying it.

It has nothing to do with fear. But if you’re under warranty like I am and will be under warranty for as long as you own it,use whatever word you want but if something ever happens to your **** and you want it fixed on their dime, you better have some kind of fear, or whatever you wanna call it, unless you got a really good lawyer. Lol.

In less than a year or 15,000 miles, you won’t be caring about warranty anyways.

First off, Han is dead… Second, when Han he said he’s got money, he actually had a lot of money.He didn’t have to worry about warranty- if he let one of his many cars get trashed just to see what somebody’s made of, he just buys another car.

If you have a good relationship with the dealer than they'll look past it. As it's been stated already the dealer would have to go through all the bcm settings, if they could even access them and find specific changes then prove that that changed caused whatever issue to deny that particular warranty claim. Remember they can't blanket deny or void your warranty for one change. It has to be proven that that change cause a particular part to fail and they can only void or deny warrant on that part. So let's say you add relays (which Jimmy07 already said that's way more obvious than using alphaobd) and something happens and the tipm ( fuse box) fails. You panic, forget about the relays bring the truck in and they determine that the cause was the relays you added. Now they can deny your warranty claim on the parts affected by the relays. Another example, probably a better one, aftermarket exhaust, you install a cat back exhaust or even replace the muffler. All you did is void the warranty on your exhaust, not the entire truck. Same goes with adding anything aftermarket or even oem parts. Unless the dealer installs those oem parts they aren't covered under warranty.. The bypass cable is almost undetectable. A tech would have to be rooting around under the dash to see the obd2 splitter on the bypass. As stated already it's not a module or anything that can be detected by the dealers computer. Even when the dealer adds there bypass to do anything it doesn't affect it.

I understand the "fear" of voiding your warranty but it's harder than you think unless your dealer has a reputation for not doing warranty work or finding reasons not too.

Once you make the changes, you can remove the bypass and the AlfaOBD Bluetooth interface. They don’t need to be hooked up for the changes to stick.

So far, the dealership that my truck came from has been good to me but, I have yet to cross that bridge of needing something done under warranty that deals with a part or piece that I’ve altered or replaced with something aftermarket so, I can’t really even begin to guess how they would handle something like that if were to come up.

I get it that anything like this isn’t going to just up and completely void your whole entire warranty without proof that any of that had anything to do with it in the first place. And yeah, I could see how a bunch of relays could raise suspicion and concern but we’ve moved past that. The relay idea is no longer talked about.

The bypass cable is almost undetectable. A tech would have to be rooting around under the dash to see the obd2 splitter on the bypass. As stated already it's not a module or anything that can be detected by the dealers computer. Even when the dealer adds there bypass to do anything it doesn't affect it.

I’m not talking about the bypass cable being detectable. I’m still waiting on confirmation to whether or not that security module can stay bypassed because in an earlier discussion concerning these bootleg sales code programmers from a long time ago, I am still under the impression that the security module has to be hooked back up in order for Chrysler’s diagnostic computer to be able to talk to the truck whenever warranty repairs or safety recall updates come up.

Is it true I can unhook the safety module and leave it unhooked? like I said before, if I can only take my dash apart one time, pull that safety module out and put that bypass cable in, and put the truck back together and leave it that way, I’d probably be a lot more interested in buying that Alpha OBD thing to make some changes to my truck. But if the time ever comes up to where I have to take my truck to the shop, and have to rip that dash apart to plug that module back in before I take it to the dealer, that’s not something I’m interested in I having to do more than once. I don’t want to have to do that every time the truck have to go th dealer.

Well, I don’t really necessarily think it is harder as you say. There are so many variables that they could use to say it’s your fault that- without getting too much into that discussion, and to make a long story short, it’s just one of those that if they find a reason to say no, and you have a damn good reason to say they’re fulla **** then it’s going to end up in a court room. I would hope my dealer would back me up

If you plan on using aev or tazer then I believe that you remove the module plug their device in and leave it in bypassing the security module. As far as if the dealer can tell it's been removed, I don't know.

With the bypass harness that @M2Mods sells the security module stays in tact and depending on if you have a 1500 or 2500/3500 you'll either have 2 or 3 connections to make. 1- unclip the obd2 port from the dash plug it into the obd2 splitter and clip in the other end of the obd2 splitter ( visually you can't tell you replaced the obd2 port). 2-(1500's) you have 1 connector that goes to a set of ports under the dash near the parking break. (2500/3500's) just have a second connector that goes into a second set of ports right above. That's all. I couldn't tell you how it works but it does. It may add missing obd2 wires that, with the harness, gets added back into the equation. Security module stays intact, you can just unplug the obd2 splitter and put the original obd2 back in place and just tuck the splitter up out of the way or disconnect the other connections without tearing anything apart.

I guess I totally misunderstood a long time ago on how that AlfaOBD thing connects and works on a 2018 and later pickup. As I said before, I was under the impression that in order to use that on my truck, Id have to pull the dash off around the radio, pull the 8.4 radio screen out of the dash, find that security module that’s behind it, unplug the connectors on both ends of it, and plug in that bypass....
